custom equipment as well.
Typical delivery time for
catalog reactors constructed of
stainless steel is two to four
weeks. For special alloys and
custom modifications, plan for
4 to 8 week delivery. For
systems or orders requiring
extensive custom design work
allow 8 to 12 weeks. Of equal
importance over the life of
your reactor is our
commitment to maintain
commonly used replacement

over-and-above the options
listed in this catalog. Special
valves, special head layouts,
electrical leads, special stands,
additional openings, unique
motors, and non-standard
materials of construction are
just a few of the modifications
we work with every day.

The User’s Responsibility
All Parr reactors and pressure vessels are designed and
manufactured with great care to ensure safe operation when used
within their prescribed temperature and pressure limits. But…
the basic responsibility for safety when using this equipment
rests entirely with the user; who must:
1. Select a reactor or pressure vessel which has the
capability, pressure rating, corrosion resistance and design
features that are suitable for its intended use. Parr engineers
will be glad to discuss available equipment and material options
with prospective users, but the final responsibility for selecting
a reactor or pressure vessel that will perform to the user’s
satisfaction in any particular reaction or test must rest with the
user - not with Parr.
In exercising the responsibility for the selection of pressure
equipment, the prospective user is often faced with a choice
between over or under-designed equipment. The hazards
introduced by under-designed pressure vessels are readily
apparent, but the penalties that must be paid for over-designed
apparatus are often overlooked. Recognizing these criteria, Parr
reactors and pressure vessels are offered in several different
styles, each designed for convenient use in daily operation within
certain temperature and pressure limits, using gaskets, closures
and other elements carefully selected for safe operation within the
limits specified for that design. But in order to preserve the validity
of these designs, all temperature and pressure limits must be
observed, and no attempt should be made to increase these limits
by making alterations or by substituting components which are
not recommended by the manufacturer.
2. Install and operate the equipment within a suitable
barricade, if required, with appropriate safety accessories and in
full compliance with local safety codes and rules.
3. Establish training procedures to ensure that any person
handling the equipment knows how to use it properly.
4. Maintain the equipment in good condition and establish
procedures for periodic testing to be sure the vessel remains
structurally sound.

Designation
Parr now uses alloy designation numbers to identify the
various corrosion
resistant alloys
available for use in
Parr reactors and
pressure vessels.
These alloys can
also be identified by
trade names and by
ASTM, ASME, DIN
and other specification numbers.
Many of the high
nickel alloys were
originally patented
and sold under trade names,
such as Monel1, Inconel1,
Incoloy1, Carpenter Alloy2,
Hastelloy3, etc. Most of the
original patents have expired
and these alloys are now
available from other reputable
suppliers, as well as from the
owners of the original trade
names.
Among the many corrosion
resistant alloys now available,
there may be two or three with
very similar compositions and
intended for use in the same
corrosive environment. In these
cases, Parr will select and offer
the most widely used alloy in
each of the basic corrosion
resistance categories, rather
than catalog and stock all three.
Each of these alloys has its
own physical strength and
temperature characteristics as
well as its own unique resistance to certain corrosive
materials. All of these factors
must be considered when
making a selection, with cost

acid systems. At ambient
temperatures it does offer
useful resistance to dilute
sulfuric, sulfurous, phosphoric
and nitric acids, but sulfuric,
phosphoric and nitric acids
readily attack T316SS at
elevated temperatures and
pressures. Halogen acids
attack all forms of stainless
steel rapidly, even at low
temperatures and in dilute
solutions.
Although T316SS offers
excellent resistance to surface
corrosion by caustics. Caustics
can cause stress corrosion
cracking in stainless pressure
vessels. This phenomenon
Reactors and Pressure Vessels — Design Features
begins to appear at temperatures just above 100° C and has
been the most common cause
of corrosion failure in stainless
laboratory vessels. T316SS
does offer good resistance
to ammonia and to most
ammonia compounds.
Halogen salts can cause
severe pitting in all stainless
steels. Chlorides can cause
stress corrosion cracking,
but many other salt solutions
can be handled in stainless
vessels, particularly neutral
or alkaline salts.
At moderate temperatures
and pressures, T316SS can be
used with most commercial
gases. In scrupulously anhydrous systems even hydrogen
chloride, hydrogen fluoride and
chlorine can be used in
stainless steel.
Alloy 20Cb-3
Alloy 20Cb-3 is an enriched
grade of stainless steel,
designed specifically for use
with dilute (up to 30 percent by
weight) sulfuric acid at elevated
temperatures. It can also be
used for nitric and phosphoric
acid systems as well as for all
systems for which T316SS
is suitable.
Alloy 400
Alloy 400 is an alloy
comprised essentially of twothirds nickel and one-third
copper. For many applications it
offers about the same corrosion
resistance as nickel, but with
higher maximum working pres-

sures and temperatures and at
a lower cost because of its
greatly improved machinability.
Alloy 400 is widely used for
caustic solutions because it is
not subject to stress corrosion
cracking in most applications.
Chloride salts do not cause
stress corrosion cracking in
Alloy 400. It is also an excellent
material for fluorine, hydrogen
fluoride and hydrofluoric acid
systems. Alloy 400 offers some
resistance to hydrochloric and
sulfuric acids at modest temperatures and concentrations, but
it is seldom the material of
choice for these acids. As would
be expected from its high
copper content, Alloy 400 is
rapidly attacked by nitric acid
and ammonia systems.
Alloy 600
Alloy 600 is a high nickel
alloy offering excellent resistance to caustics and chlorides
at high temperatures and high
pressures when sulfur
compounds are present. In
caustic environments, Alloy 600
is unexcelled. It also is often
chosen for its high strength
at elevated temperatures.
Although it can be recommended for a broad range
of corrosive conditions, its
cost often limits its use to only
those applications where its
exceptional characteristics
are required.

Alloy B-2
Alloy B-2 is an alloy, rich in
nickel and molybdenum, which
has been developed primarily
for resistance to reducing acid
environments, particularly
hydrochloric, sulfuric and phosphoric. Its resistance to these
acids in pure forms is unsurpassed, but the presence of
ferric and other oxidizing ions
in quantities as low as 50 ppm
can dramatically degrade the
resistance of this alloy.
Alloy C-276
Alloy C-276 is a nickelchromium-molybdenum alloy
having perhaps the broadest
general corrosion resistance of
all commonly used alloys. It
was developed initially for use
with wet chlorine, but it also
offers excellent resistance to
strong oxidizers such as cupric
and ferric chlorides, and to a
variety of chlorine compounds
and chlorine contaminated
materials. This alloy is used
extensively to combat the high
temperature and high pressure
corrosive conditions encountered in drilling for sour
petroleum deposits and in other
oil field applications.
Alloy C-2000
Alloy C-2000 is a new nickelchromium-molybdenum alloy
from Haynes International. It
was approved for coded
pressure vessels in the Spring
of 1997. While the wealth of
application data that is available
for the earlier members of the
Alloy C family of alloys does
not yet exist for Alloy C-2000,
initial reports suggest that this
alloy will extend the already

Titanium
Titanium is an excellent
material for use with oxidizing
agents, such as nitric acid, aqua
regia and other mixed acids. It
also offers very good resistance
to chloride ions. Reducing
acids, such as sulfuric and
hydrochloric, which have unacceptably high corrosion rates in
their pure form can have their
corrosion rates in titanium
reduced to acceptable levels if
relatively small quantities of
oxidizing ions, such as cupric,
ferric, nickel or even nitric acid
are present to act as corrosion
inhibitors. This phenomenon
leads to many successful applications for titanium in the
hydrometallurgy field where
acids, particularly sulfuric acid,
are used to leach ores. In these
operations the extracted ions
act as corrosion inhibitors.
Prospective users must
remember that titanium will
burn vigorously in the presence
of oxygen at elevated temperatures and pressures. While
there have been many
successful applications in
hydrometallurgy where oxygen
and sulfuric acid are handled in
titanium equipment, the danger
of ignition is always present
and must be protected against
whenever titanium and oxygen
are used together.
Commercially pure titanium
is available in several grades.
Grade 2 is the material most
commonly used for industrial
equipment since it can be fabricated by welding and is
approved by the ASME Code
for Unfired Pressure Vessels.
Grade 4, which has slightly
higher trace levels of iron and
oxygen, has higher strength
than Grade 2 but it is not
suitable for welding and it is
not covered by the ASME Code.
Since most Parr vessels are not
welded, they usually are made
of Grade 4 to obtain higher
working pressures than can be
obtained with Grade 2. Grade 7,
containing small amounts of
palladium, and Grade 12
containing small amounts of
nickel and molybdenum, offer
enhanced resistance to certain
environments and can be used
for Parr reactors and pressure
vessels if suitable billets can
be obtained.
Zirconium
Zirconium offers excellent
resistance to hydrochloric and
sulfuric acids but, as with
Alloy B-2, oxidizing ions such as
ferric, cupric and fluorides must
be avoided. Zirconium also
offers good resistance to
phosphoric and nitric acids, and
to alkaline solutions as well.
Two different grades are
available: Grade 702 containing
hafnium is the standard
Reactors and Pressure Vessels — Design Features
commercial grade offering the
best resistance to most
corrosive agents, Grade 705
containing small amounts of
both hafnium and columbium
has better strength than Grade
702, allowing higher working
pressures when it is used in
pressure vessel construction,
but the corrosion resistance of
Grade 705 is not quite as good
as Grade 702. Grade 702 is
generally more widely available
from commercial stocks of raw
materials.
Carbon Steel
Carbon Steel is usually used
for laboratory reactors only
when it is desired to duplicate
construction material used in
plant equipment. Because it
rusts easily, carbon steel
vessels are not carried in stock
and must be made to order,
often resulting in costs higher
than stainless steel equipment
despite the lower material cost
for carbon steel.

Pressure &
Temperature Limits
Pressure and Temperature Limits
he maximum pressure
and temperature at which
any reactor or pressure
vessel can be used will depend
upon the design of the vessel
and the materials used in its
construction. Since all materials
lose strength at elevated
temperatures, any pressure
rating must be stated in terms
of the temperature at which it
applies. All Parr listings show
the maximum working pressure
for each reactor and pressure
vessel in pounds per square
inch (psi) or bar at 350˚ C for
vessels constructed of Type 316
Stainless Steel. Table II provides
a set of multipliers which can
be used to convert 350˚ C
pressure ratings for any T316SS
vessel to higher or lower
temperatures. It can also be
used to determine the corresponding ratings for vessels
of the same design made of
other materials.
T
Table II
Pressure Rating Factors
Although lower operating
temperatures permit higher
working pressures, the pressure
rating for a vessel should never
be increased to more than
20 percent above its rating at
350˚ C. These conversions are
only rough approximations.
Actual ratings of other materials and ratings for other
temperatures will be
computed and assigned by
the Parr Engineering
Department.
Although pressure rating
factors for temperatures as
high as 600˚ C are included in
Table II, many Parr vessels
cannot be used at these higher
temperatures because of gasket
material restrictions or other
design limitations. The
maximum working temperature
for which allowable stress
values are published in the
ASME Pressure Vessel Code are
included in Table II. No reactor
or pressure vessel should be
operated above these
maximum temperature limits.
Examples:
What is the maximum
pressure rating at 450˚ C for a
T316SS vessel rated at 1900
psig at 350˚ C? (1900)(0.95) =
1805 psig
What is the maximum
pressure rating at 450˚ C for an
Alloy 400 (Monel) vessel when
the same vessel made of
T316SS is rated at 1900 psig at

The A1120HC and A1180HC
models are the standard units

adjoining table. The A1750HC2
model is a special high torque
drive intended primarily for
heavy loads and high viscosity

Modified
Magnetic Drives
Alternate Packed
Gland Drive
The standard A1120HC Series
and A1180HC magnetic drives
used in all Parr reactors operate
with small diameter stirrer
shafts which require a lower
guide bearing or foot bearing to
stabilize the stirrer when
running at high speeds.
Different lower bearing arrangements are used to match the
configuration of each drive
system. To provide stirrers that
will operate satisfactorily
without a lower bearing, Parr
offers three modified drives,
A2140HC, A2160HC, and
A2170HC which have the same
ratings as the standard units,
but are designed for use with
larger shafts which do not
require a lower guide or foot
bearing. These self-supporting
stirrers can be operated at
speeds up to 2500 rpm. They
are particularly attractive for
applications in which there is
no room for a lower bearing, or
for use with abrasive slurries or
other reactants which might be
detrimental to an immersed
bearing.
For reactors in which there
is insufficient space for a
magnetic drive, or where a
direct mechanical drive is
preferable to a magnetically
coupled system, Parr can
furnish a self-sealing packed
gland which will maintain a
reliable seal on the stirrer shaft
at working pressures up to
2000 psig (13.89 Mpa). It will
also hold a vacuum down to
approximately 1 mm of
mercury. These glands are
made to a Parr design which
uses a combination of cones
and O-rings in combination
with pressure from within the
vessel to maintain a positive
seal on the rotating shaft. This
self-sealing feature eliminates
the need to tighten the gland
repeatedly during a run and it
avoids the danger of overtightening or excessive loading
on the packing elements. The
packing can usually be
expected to last from 200 to
400 hours. Repacking, when
necessary, is a simple task
requiring no special tools.

With either style, the closure
parts come completely away

with all of its fittings can be
lifted from the cylinder or the
cylinder can be dropped away
without disrupting any attached
fittings. When cap screws are
used, they are simply tightened
or loosened, they are never
completely removed from the
split ring or drop band. This
saves time both in opening and
closing the vessel and in
looking for lost parts.
Split-ring closures add
many attractive features to

disturbing any connections or
fittings attached to the head.

Gaskets & Seals
Gaskets and Seals
here are four different
types of gasketing
material for the main
head seal in Parr reactors and

own advantages and limitations.

improves with each use as the
gasket is forced into the faces
on the head and cylinder. It also
is a very forgiving seal which
does not require the special care
needed to achieve a uniform
loading, which is essential when
working with a metal or other
non-plastic gasket material.
Flat Teflon Gasket

O-Rings
Contained Flat
PTFE Gaskets for
Temperatures to

The traditional and most
popular main head gasket for
Parr vessels is a flat gasket
made of a PTFE fluoropolymer.
In Parr flat gasket closures the
gasket is held in a recess in the
vessel cover. A matching pilot
on the cylinder closes the
recess, leaving the gasket
completely confined with only a
small inside edge exposed to
the reactants within the vessel.
This combination of complete
gasket containment and the
exceptional properties of PTFE
materials produces a reliable
closure for working temperatures up to 350˚ C.
Flat contained gaskets require
a loading pressure greater than
the highest pressure to be
developed in the vessel in order
to maintain a tight seal. In Parr
designs this is produced by
tightening a ring of cap screws
in a split-ring cover clamp.

O-Ring Seal

High Pressure Metal Gasket
Reactors and Pressure Vessels — Design Features
Parr has greatly expanded its
offerings of reactors and vessels
which feature self-sealing O-ring
closures. In these designs the
sealing force on the gasket is
developed from pressure within
the vessel itself, eliminating the
need for cap screws in the split
ring to pre-load the seal. In
these self-sealing closures the
split ring sections simply lock
the head and cylinder together.
The physical properties of
available O-ring materials are
the governing factors to be
considered when selecting an
O-ring closure. Since O-ring
elastomers will not withstand
operating temperatures as high
as PTFE polymers, the selection
of a self-sealing closure
becomes a tradeoff between
lower operating temperatures
and an easy opening design.
Although there are a number of
available O-ring materials, the
real choice comes down to two:
Fluoroelastomer (FKM)
O-rings, such as Viton are a first
choice for Parr self-sealing
closures. They have good

Perfluoroelastomer (FFKM)
O-rings such as Kalrez have
extremely broad chemical
resistance and can be used at
working temperatures up to
300˚ C. Unfortunately, this
material should probably be
considered an “exotic” because
it costs approximately 80 times
as much as an FKM O-ring. And
while it will raise the allowable
working temperature to 300˚ C,
as a practical matter, most users
intending to work at this
temperature level would be well
advised to choose a closure
with a flat PTFE gasket and a
350˚ C temperature limit.
Other exotic O-ring materials
are available, and there are
economically priced materials
such as ethylene-propylene that
will resist some materials that
cause FKM to fail, with only
slight sacrifices in operating
temperatures. But, except for
specific applications, they do
not currently offer a performance/price benefit as attractive
as Kalrez.

For operating temperatures
above 350˚ C, Parr uses a
recently developed flexible form
of graphite, called Grafoil, which
has proven to be an excellent
high temperature sealing
material. It consists of flexible
layers of graphite bonded
together to produce a gasket
that is almost as easy to seal as
a flat, PTFE gasket, but with an
almost unlimited temperature
range and excellent chemical
resistance.
Parr has converted all of its
standard designs to accept a
flat, Grafoil gasket whenever
operating temperatures above
350˚ C are required, replacing
the metal gaskets formerly used
for high temperatures. These
flexible graphite gaskets are
held in grooves identical to the
ones used for PTFE gaskets and
sealed with the same split-ring
closures. This makes it possible
to substitute a PTFE gasket
whenever the vessel is to be
used at temperatures below
350˚ C. Grafoil gaskets are
reusable, but their service life is
shorter than can be obtained
with a PTFE gasket.
Metal Gaskets
Metal gaskets have traditionally been the only gaskets
available for use at temperatures above 350˚ C. Parr has
designs for diamond crosssection metal gaskets which
can be furnished for special
applications, but we would
recommend the flexible
graphite gaskets described
above for most applications.
Trademarks of Sealing Materials
A number of gasketing materials have so dominated their product categories that their
Trade Names have become more common than the actual material designation itself. In an
attempt to respect the value of these Trade Names and their proper usage and to minimize

cylinder remaining in the
heater, but the head must be

These removable reactors
will be attractive to users that
intend to operate fairly simple
batch systems rather than
continuous flow arrangements,
and that want to be able to
remove the vessel for product
recovery, charging or cleaning.
They will also appeal to those
that need to prepare the vessel
in a special atmosphere, or
want to clean the cylinder and
stirrer at a site away from the
reactor stand and heater. There
is also the added advantage of
being less expensive than the

vessel, and for safe operation the
maximum liquid charge held in the vessel
used in sealed batch operations should not
exceed two-thirds of the available free
space. Generally, several vessel depths are
offered within most series, and reactor
sizes can be reconfigured with conversion
parts. It is also true that the larger sizes are
usually more expensive, but the pricevolume curve is not a smooth one.
Maximum Operating
Pressure
Parr offers two basic operating ranges;
1900 psi for general purpose and 5000 psi
for high pressure applications. Because of
the nature of the design process, the small
Micro and Mini Reactors (25 to 600 mL)
can be rated at a higher, 3000 psi (207 bar)
maximum pressure. Since these models
are less expensive and much easier to
26
Reactors and Pressure Vessels — Stirred Reactors
handle than reactors designed for higher
pressures, they are an attractive choice
for use in the sub-high pressure range.
Substantial savings are available if the
user can avoid the tendency to over-specify
the expected operating pressure. ASME
design criteria provides for an inherent
4:1 safety factor, typically sufficient for
most applications.
Maximum Operating
Temperature
Traditionally the choices here have been
up to 350˚ C for vessels with PTFE gaskets
and up to 500˚ C for flexible graphite (previously metal gaskets.) Parr has now added
the option of a self sealing O-ring closure
for general purpose vessels with volumes
from 100 mL to 2 gallons. These quick
closing designs are practically limited to
225˚ C although this can be raised to 300˚ C
with exotic/expensive O-ring materials.
Mounting Style
There are actually two aspects to the
mounting question: the first is bench top or
➥
Stirred
Reactors

Choosing your
Parr Stirred Reactor
➥
floor stand. This choice is
generally limited to reactors
with volumes of 600 mL thru 2 liters
since reactors smaller than that are
always mounted on the bench and
larger reactors are restricted to floor
stand mountings. Generally a broader
motor choice and better access to a
bottom drain valve are available on
floor stand models.
A second mounting choice is
between a removable vessel or fixed
head design. In the removable vessel
style the complete vessel assembly
(only the head in 1 gallon and larger)
is removed from the heater for
charging, product recovery and vessel
cleaning. As the description implies,
in the fixed head style the head
remains fixed in the mounting and the
reactor cylinder and heater drop away
to open the vessel. The fixed head
design is a recent addition to the Parr
line in response to those users who
wish to leave inlet and feed lines,
discharge and vent lines, condensers
and similar connections undisturbed
between runs. This option is limited to
the midrange (300 mL to 2 gallon) of
the reactors as it is not practical for
the very smallest or largest designs.
Size
25 mL
18.75 L
Parr Instrument Company offers
laboratory reactors and pressure
vessels in sizes from 25 mL to 18.75 L.
Generally it is best to select a size
that will allow for 1/3 free space.
This allows for some liquid
expansion during the heating
phase of a reaction.
Pressures (psi)
1900
3000
5000
Maximum operating pressures are
determined by adherence to the ASME
pressure vessel design criteria. There
are two ranges; up to 1900 psi and up
2
to 5000 psi. In some cases reactors in
Select Appropriate Series
the 25 mL to 600 mL range can be
rated to 3000 psi.

Standard Fittings
Options
There are a number of
options to be considered and
selections to be made in order
to complete the specifications
for a reactor. These include:
some reactors a cooling coil is
furnished as a standard fitting.
In others, a coil can be added as
an option in either spiral or
serpentine configurations.
1. Material of Construction.
The majority of organic reactions can be handled in stainless
steel, but ten other corrosion
resistant alloys are available to
provide vessels suitable for use
with a wide range of corrosive
acids, bases, salts and gases.
Special alloy construction can be
provided for both the internal
parts of the vessel and the
external valves and fittings, but
there is a considerable cost
savings if the user will accept
standard external parts made of
stainless steel instead of a
special alloy.
5. Gage and Rupture
Disc Ranges.
These components are
available in many ranges and
resolutions appropriate for both
the reactor and the intended
work to be accomplished.
2. Magnetic Drive.
On all but the smallest
reactors the standard magnetic
drive can be replaced with a
higher torque model to handle
high viscosity stirring loads. The
standard, general purpose drives
will normally handle viscosities
up to 25,000 centipoise.
7. Certification.
ASME, TÜV and CE
Certifications are available
for users who require these
recognized quality assurance
certifications.
3. Stirrer Drive Motor.
High viscosity reactants
will also dictate the choices
of a larger stirrer drive motor
and possibly an alternate
power train.
4. Cooling Coil.
An internal cooling coil can be
installed in all reactors (except
the Micro sizes) to remove the
heat of a reaction and/or to cool
the vessel at the end of a run. In
6. Instrumentation Package.
Two different temperature
controllers and an alternate
computer-based process
controller are available, each
with optional add-on modules
for pressure measurement, high
temperature cut-off, stirring
speed and stirring load display.
8. Electrical Supply.
Parr reactors can be furnished
to draw power from any
standard electric supply system
in the world.
9. Custom Options.
A wide range of custom
options such as special
openings in the head or cylinder,
windows, special valves, custom
heaters or jackets, explosion
proof wiring and volume modifications are available.
10. Accessories.
Various accessories, such
as glass and PTFE liners,
condensers, catalyst holders
and alternate stirrers are
available to further adapt these
reactors to the individual
user’s applications.

of the above options, and for
additional selections as well, is

hese are the smallest of
all Parr Stirred Reactors.
They will be a good
choice for chemists working
with very expensive materials
or materials only available in
small amounts. They will also
appeal to users who wish to
minimize the risks associated
with hazardous materials or
reactions by restricting the
reactants or products to a
minimum. They also minimize
the quantities of waste products
which may require special
disposal procedures.
These micro reactors have
been designed to provide as
many of the features of the
larger vessels as possible in the
limited space available. All of
the standard head fittings are
provided, but cooling is not
available unless some of the
normal fittings are eliminated.
A convenient screw cap and
O-ring closure allows these
small vessels to be closed by
simply turning down a screw
cap until it is hand tight. No
wrenches or other tools are
required. Normal heating rates
are achieved using heaters

Reactors. Although they
are called “Mini” reactors,
they offer a range of sizes large
enough to work with significant
sample sizes, yet small enough
to be handled with ease by all

both fixed head and removable
vessel styles, with a choice of
either a self sealed O-ring
closure with no cap screws
for working temperatures up
to 225˚ C, or with a flat, PTFE
gasket for higher temperatures
up to 350˚ C sealed with six
cap screws in a split-ring

Although internal and
external space is limited in
these small vessels, gas
entrainment impellers, catalyst
baskets, condensers and other
options are available. All
reactors in this series can also
be converted easily from one

4561 Mini Reactor, 300 mL, with 4843 Controller
size to another by simply
substituting a longer or shorter
cylinder with corresponding
internal fittings, but any size
change may require a different
heater. A longer cylinder can be
heated in a shorter heater, but a
shorter cylinder must never be
heated in a longer heater
because the heater will burn out
if the entire heating surface is
not in contact with a metal
vessel.
Reactors and Pressure Vessels — Stirred Reactors
The support system for these
Mini Reactors is designed
specifically to provide stability
at stirring speeds up to 2500
rpm, in a compact mounting
small enough to fit into a
laboratory hood. The support
system can also be adapted to
accept any of the smaller
vessels from the 4590 Micro

hese are the largest of the
Parr Reactors that can be
handled on a bench top.
They can be furnished with
either a self-sealing, O-ring
closure for working temperatures up to 225˚ C, or with a
flat, PTFE gasket for higher
temperatures to 350˚ C. Both
fixed head and removable
vessel designs are available.
It should be noted, however,
that the 2 liter, fixed head
model is tall and may not be
convenient to operate on a
standard height bench top. We
recommend using a floor stand.
(See Series 4530)
With their larger diameter,
these mid-size reactors have
sufficient space for special
modifications, such as: an
internal cooling coil, a bottom
drain valve, a ball valve on a
solids charging port, catalyst
addition devices, condensers,
electrical feed-thrus and more.
Details are provided in the

his series of reactors will appeal to users who
have any of the following needs:
• Reactors Configured for Polymer Studies.
The reactors in this series are mounted on a sturdy
floor stand which will accommodate larger stirrer drive
motors and stronger power trains than are available
for the bench top models. With these options it is
possible to provide the high torque and low stirring
speeds required for work with polymers and other
mixtures with viscosities of 1 million centipoise and
more. These mountings also permit the installation of
a drain valve in the bottom of the vessel for convenient
removal of the reaction mixture while it is still hot.
• Reactors Requiring Extensive Modifications.
Floor stand mountings provide a good base for reactor
modifications and for the addition of accessories, such
as: condensers, packed columns, special motors,
special heaters, jacketed vessels, automatic valves or
regulators, and many others.
• Reactors that Need to be Moved. Users who
plan to operate these reactors in a area where a bench
top is not available, or who wish to move the reactor
to storage when not in use, will appreciate the
movable floor stand design of the Series 4531 and
4532. All of the 1 and 2 liter reactors in this series can
be furnished with either a self-sealing, O-ring closure
for working temperatures up to 225˚ C, or with a flat,
PTFE gasket for higher temperatures to 350˚ C. Both
fixed head and removable vessel designs are available.

his is a new series of
stirred reactors designed
for users who need higher
operating pressures than the
2000 to 3000 psi offered by the
General Purpose Reactor, but
do not require the high operating temperatures provided by
the Series 4570 High PressureHigh Temperature Reactors.
These reactors offer working
pressures to 5000 psi (350 bar)
at temperatures to 350˚ C.
These vessels have been
designed with outside dimensions comparable to the Series
4520 and 4530 Reactors so that
they can use the same support
system, stirrer drive and heater
as these popular general
purpose models. This provides
not only an attractively priced
high pressure/moderate
temperature system, but also
reactors that can be interchanged with the 1 and 2 liter
sizes. The thicker sections
required for higher operating
pressures reduces the volumes
of these reactors to 600 and
1200 mL.

The 600 mL size can be
used in either the bench top or
floor stand mountings. While
the 1200 mL reactor will fit in
the bench top heater of the
Reactors and Pressure Vessels — Stirred Reactors
Model 4522 Reactor, it
is too heavy to be handled
comfortably on a bench top
and the floor stand version
is suggested.

Maximum Operating Temperature
350˚ C w/ PTFE Flat Gasket
he Model 4555 Reactor
with its 5 gallon (18.75 L)
capacity is the largest
stirred reactor offered by Parr.
The 4556 Model is a similar unit
in a 10 liter (2.6 gal) mid-size
between the larger 5 gallon
design and the smaller
1 and 2 gallon models in the
4550 Series.
These reactors are available
only with a flat, PTFE gasket in
a removable head designed for
operating temperatures up to
350˚ C maximum. A fixed head
is not offered because it would
become too tall for reasonable
operation, especially if equipped
with a bottom drain valve,
which is usually requested.
The vessel is held in a support
system which minimizes the
physical effort required to
handle these heavy components. A hoist attached to a
support column provides a
convenient means for lifting
the head and cylinder out of the
stand and transferring these
parts to an opening in the right
hand table. Since these vessels
are usually equipped with a
T
54
4555, Floor Stand Reactor, 5 Gallon, Manual Hoist, with 4842 Temperature Controller
bottom drain, the cylinder will
probably remain in the heater
most of the time, but it can be
lifted out when necessary.
These reactors are generally
used for pilot plant or for
custom chemical production
purposes, usually with a variety
of attachments added to the
basic units. Special heaters,
3-zone heaters, larger motors,
heavier stirrer drives and
remote controls appropriate to
the size of these reactors have
been designed and are
available. Other volume,
pressure and temperature limits
Reactors and Pressure Vessels — Stirred Reactors
have also been built into these
units within the outside dimensions of the 5 gallon system,
including a special stirred
system rated as high as 5000 psi
and 500˚ C.
Approximately 7.5 kW of
electric power is required to
operate these reactors. This is
usually too large a load to be
drawn from a single phase,
230 volt line. This requirement
must therefore be considered
carefully when ordering any of
these reactors to be sure that
the ordered unit is configured to
operate on the available power.

ll Parr reactors are
normally equipped with
open type, variable
speed motors, electric heaters
and controllers intended for use
in non-hazardous environments.
These standard units can be used
in most laboratories without
undue hazard, but there will be
situations where the installed
equipment must be considered
explosion proof. Parr offers
various optional stirrer drives and
heating systems to meet these
strict requirements.

USA and
Canadian Codes
Designing electrical equipment
to be operated in hazardous
location is a complex subject,
governed by extensive national
electrical codes and supplemented by local regulations
which require that all electrical
equipment installed in a
governed location must be
approved for use with the specific
gas, vapor or dust that will be
present in that location. USA and
Canadian electrical codes classify
hazardous locations according to
the nature and concentration of
specific hazardous or flammable
materials. These are divided into
three classes:
Class I - Flammable liquids,
gases or vapors.
Class II - Combustible or electrically conductive dusts.
Class III - Easily ignitable
fibers or flying particles.
There are two divisions within
each of these classes.
Division 1 - Where the flammable material exists in the
atmosphere under normal operating conditions.
Division 2 - Where the
hazardous material is confined
within a closed system from
which it may be released only
under abnormal conditions, such
as a leak in the system.
Class I locations are further
subdivided into four groups, A, B,
C and D which identify specific
explosive gases and vapors.
Explosive dusts and fibers in
Class II are subdivided into
Groups E, F and G. Most
hazardous applications for Parr
Reactors and Pressure Vessels — Optional Fittings
apparatus will occur in atmospheres identified by Class I,
Group A for acetylene, Group B
for hydrogen and Groups C and
D for most other combustible
gases and vapors. Class II, Group
F covers coal dust. Most other
combustible dusts, such as flour
and grain, are in Group G.
Minimum ignition temperatures
and energy levels are established
for specific materials in each
group.
The European Community,
International Electromechanical
Commission (IEC) has corresponding classifications for
hazardous locations. Parr will
work with all users to provide
equipment compatible with their
own local codes.
The several components in
Parr reactor systems which may
be considered hazardous, and the
steps that can be taken to reduce
or eliminate the hazards they
represent, are described below.
Explosion Proof
Motors
Because of sparking from
brush contacts, electric motors
clearly represent the principal
explosion hazard introduced by a
stirred reactor. Electric motors
approved for Class I, Groups C
and D, and Class II, Groups F and
G atmospheres are readily
available in most sizes and
voltages. These sealed motors
are suitable for most hazardous
applications, and they are sometimes used with hydrogen, but
they are not approved for Class B
atmospheres. To meet Class B
requirements, a motor
➥
Optional
Fittings
3
➥
must be purged by building up a
positive pressure of air within the
motor to prevent explosive gases
or vapors from reaching electrical
ignition sources. This requires a
special, air purged motor which
can be provided when required.
An alternate method of dealing
with the explosion hazard is to
use an air driven motor. These
are powered by compressed air
and offer a convenient and satisfactory drive system for use in
flammable atmospheres,
including hydrogen. They are
available in sizes suitable for
most Parr reactors.
Explosion Proof
Heaters
The easiest way to provide an
explosion proof heater is to use a
steam or hot oil jacket and ensure
that the highest temperature that
can be reached in the jacket is
well below the minimum ignition
temperature for the specific
hazardous atmosphere in which it
will be installed. An aluminum
block heater can be considered
explosion proof if it has
explosion proof wiring, and if it is
operated with an auxiliary
controller that will hold the
surface temperature below a safe
maximum. Electric heaters
purged with clean air can also be
considered explosion proof, but it
is doubtful that seals can be
maintained in a purged heater to
provide true protection over a
long period of time.
Please see page 69 for
additional information on
heater selection.
Explosion Proof
Wiring
In an explosion proof system,
all electric wiring with significant
voltage or current carrying capability must be routed in approved
sealed conduit or in specially
sealed flexible cables. All terminations and switches must be
contained in approved boxes or
housing. The user must provide
all local wiring and connections
to a power supply, and must
ensure that the installation meets
all requirements of the local
electrical code.
Certain sensors, such as thermocouples, pressure transducers
and tachometer pickups carry
such low electric loads that they
are a potential ignition source
only in the event of a most
unusual failure. In many
installations these low hazard
components are not seen as a
problem. They can, however, be
protected with isolation barriers
which will make them intrinsically
safe even in an unusual failure.
These energy limiting electronic
barriers can be provided where
required.
Explosion Proof
Controllers
The most commonly used
method for dealing with the
ignition hazard introduced by a
temperature or process controller
is simply to locate the controller
outside of the hazardous atmosphere. Another choice is to install
the controller in a cabinet which
can be purged with clean air
within the hazardous location.
Special Systems
Parr can furnish systems
approved for use in hazardous
locations up through Class I,
Division 1, Group B in which
specific hazardous gases will be
present. Each of these formally
approved systems must be
designed and built on a custom
basis, with all current carrying
wiring and fittings installed in
accordance with the requirements discussed above.

Stirring Motors and Drives
Torque vs.
Stirring Speed
The standard, open-type,
variable speed motor installed
on each Parr reactor will produce
stirring speeds from zero to
between 700 and 800 rpm with a
torque adequate to drive the
installed impellers in average
viscosity mixtures. Higher horsepower motors and special stirrers
can be provided for higher
viscosities, and drive pulleys can
be changed to produce higher
stirring speeds, but several
basic rules must be considered
when changing any of these
components.
The highest torque from any
motor is obtained at lower stirring
speeds. Increasing the stirring
speed reduces the torque in
inverse proportion to the speed.
For operations involving high
viscosity mixtures, the motor
size, the type of impeller and the
stirring speed must be matched
to provide an effective mixing
system.
As a general rule, the magnetic
coupling installed on each Parr
reactor will have a torque rating
considerably higher than the
torque obtainable from any of the
motors offered for use with that
apparatus, thus the magnetic
drive should be able to handle
any of the optional motor/stirrer
combinations.
Air Motors
Air -driven motors can be
installed on any reactor, offering
an attractive option for many
applications since they provide
both speed adjustment and meet
explosion-proof requirements as
well. The horsepower rating,
torque, and available speed are
all dependent upon the pressure
and available volume of the
driving air source. Maximum
torques are delivered at relatively
slow speeds and maximum
horsepower is delivered
at high speed.

Explosion proof motors with
variable speed control can be
furnished for any Parr reactor.

Heater Options
arr has designed standard
electrical heaters for all of
the reactors in our product
line. Different types of heaters are
used for individual reactors to
best meet the operational needs,
heating load, and expected operating temperatures. The standard
heater type and power rating for
each reactor model are listed in
the reactor specification tables.
The standard designs will be
one of the following:
Clamp-on Band Heater.
These are normally used for very
small reactors where maximum
watt densities and heat transfer
are required by the small heating
area available on the vessel.
Rigid Heating Mantles.
These are quartz fabric mantles
housed in aluminum shells. They
are used on moderate sized
reactors in designs where the
heater can be moved onto or off
of the vessel. They are light
weight and easy to handle, but
they are not used to support the
weight of the vessel and they are
generally limited to operating
temperatures of 350˚ C or less.
Calrod-Type Sheathed
Element Heaters. These are
rugged heaters with Calrod-type
elements held within a metal
shell. They are used for medium
to large reactors for operating
temperatures to 350˚ C, where the
heater itself forms a part of the
reactor support.
P
Ceramic Heaters. These
are special purpose heaters with
an electric element embedded in
a shaped ceramic body which is
held within an insulated metal
housing. They are used for
reactors designed for temperatures to 600˚ C and for very large
multizone heaters.
Optional and Custom
Heaters. Parr offers a variety of
heater designs which can be
substituted for the standard
heater normally furnished with
each reactor. Most of these can
also be used with Parr non-stirred
pressure vessels as well. The
principal features and recommended applications for these
heaters are described below.
Flexible heating mantles can
be furnished for many different
applications. These are similar to
the rigid type described above
except they are not held in an
aluminum housing. They have a
flexible fabric outer case for electrical and thermal insulation. This
type of mantle is particularly
useful for heating vessels with
irregular shapes, such as those
with windows in the cylinder
wall, since they are flexible and
can be split and laced onto a
vessel around any external
protrusion. As with rigid mantles,
they will produce temperatures
up to 400˚ C, but they are limited
to watt densities of 10 watts per
square inch. This type of heater
can be made to cover any of the
vessels offered by Parr, and they
are sometimes preferred when
only moderate temperatures are
required. Since they are
constructed of cloth, an electrical
ground wire cannot be provided.

Aluminum block heaters are
available on special order for
nearly all Parr reactors and
pressure vessels. They are made
by casting a Calrod-type heating
element into an aluminum jacket
which is designed and machined
to fit the outside contours of the
vessel to be heated. The heater
is cast in two halves which are
bolted together and clamped
onto the vessel,
resulting in

direct contact and excellent heat
transfer from the aluminum block
to the vessel. A cooling coil is
cast into the block and used
either for cooling with cold water
or heating with steam or other
liquid.
Aluminum block heaters have
three distinct features which
recommend them for many
applications:
(1) Since there is no dead
space within these heaters,
explosive vapors cannot reach
the heating element and the
heater can be considered
explosion proof, provided it is
equipped with explosion proof
wiring and a safety cut-out to
ensure that the heater will
not exceed a specified temperature limit.
(2) With heat spread uniformly
throughout the aluminum block,
uniform heating is applied to all
surfaces of the vessel, similar to
the uniform heating and rapid
response obtained with a steam
or hot oil jacket, but without
requiring costly steam generators, oil baths, circulating pumps
and other accessory equipment.
(3) Since there is a cooling coil
in the aluminum block, a block
heater can also provide external
cooling for controlling an
exothermic reaction without the
internal clutter and cleaning
problems associated with internal
cooling coils. Eliminating an
internal coil also permits the use
of spiral, anchor or other stirrers
which cannot be used with an
internal coil.
Steam or Oil
Jackets
A jacket can be welded to the
outer wall of most Parr pressure
vessels to provide a means for
heating or cooling the vessel
with a hot or cold liquid
or steam. This type of heating
is ideal for users who want
Aluminum Block Electric Heater with
Built-in Cooling Coil
to duplicate plant operating
conditions, using a jacketed
reactor comparable to jacketed
equipment commonly used in a
plant. Since there are no electrical components in a steam
jacket, and since the maximum
temperature can be controlled by
controlling the temperature of the
heating medium, a jacketed
vessel will be accepted as
explosion proof and suitable for
use in hazardous atmospheres.
Rapid and uniform heating can
be attained with a jacketed vessel
since the heating medium is in
direct contact with the vessel.
And by controlling the
temperature of the heating
medium, temperature overshoots
can be avoided when working
with sensitive materials. Jackets
can be equipped with internal
baffles to ensure uniform
distribution of the heating
medium.

Turbine Type
Impellers
The standard impellers for Parr
reactors are usually equipped
with turbine type impellers which
produce an excellent mixing
action over the range of stirring
speeds at which these reactors
usually operate. These impellers
are made in four-blade and
six-blade styles, with the smaller
four-blade impellers used only on
Micro and Mini Reactors. They
can be positioned any where on
the stirring shaft, with one
impeller usually located near the
bottom of the vessel and a
second impeller positioned near
the base of the vortex. Impellers
and shafts are furnished in the
same materials as the reactor in
which they will be used. These
impellers generally provide
excellent mixing for systems with
effective viscosities up to approximately 50,000 centipoise.

Anchor Stirrers
Anchor stirrers are available in
several configurations for use
with moderate to high viscosity
materials. This type of stirrer
usually works best in vessels with
an inside depth to diameter ratio
of 1.5 to 1 or less. They are
intended to operate at relatively
slow speeds and generally
require a heavy duty drive
system capable of generating
70
and delivering sufficient torque
to the agitator. Three basic types
are offered:
1. A U-shaped, flat bar anchor.
2. A flat blade, paddle type
anchor.
3. A three-arm, self centering
anchor with PTFE wiper blades.
All of these designs may not
be appropriate or available for
each reactor size. Please contact
the Parr Technical Service
Department for assistance in
selecting an anchor stirrer
suitable for the intended operating volume and viscosities.
Reactors and Pressure Vessels — Optional Fittings
Spiral Stirrers
Spiral stirrers can be installed
in any 1 liter, 2 liter or 1 gallon
reactor to produce a positive
down thrust (or lift) action when
working with viscous polymers or
other high viscosity mixtures.
They work best in floor stand
reactors with adjustable speed,
heavy duty drive systems. Either
left-hand (down thrust) or righthand (lift type) spirals are
available. The down thrust spiral
is the preferred style for heavy
suspensions.

Gas Entrainment
New Stirrer
Design
Parr is pleased to introduce a
new series of gas entrainment
impellers for users who want to
obtain maximum gas dispersion
into a liquid system. This is
obtained with a unique impeller
attached to a hollow stirring shaft
through which gases are continuously recirculated from the head
space above the liquid to the
impeller. Gas enters openings
near the top of the shaft and is
expelled through dispersion ports
located at the tips of the
impellers. As with all impellers,
the speed of the stirrer creates a
vacuum at the tip of the impeller.
In this new Parr system with
dispersion ports located at the
very tips of the impellers, the
higher the stirring speed – the
higher the vacuum – and the
higher the driving force for this
very effective gas dispersion
system.
These impellers are offered
as a complete package which
includes the impeller, the hollow
shaft with coupling, and any
required foot bearings and
brackets for the intended
reaction. The baffles are a
separate option which must be
ordered separately.
Since these gas entrainment
impellers operate best in the
800 - 1200 rpm range, users will
want to ensure that their stirrer
drive system is set up to deliver
these operating speeds.
Baffles Help
Because it is the relative speed
of the tip of the impeller to the
liquid phase that governs the
mass transfer, baffles which
impede the rotation of the liquid
with the impeller can greatly
enhance the operation of these
gas entrainment impellers. While
some natural baffling is provided
by the internal thermowell, dip
tube and cooling coils, the
removable baffles listed in the
table are recommended for use
with these impellers. These
removable baffles may also be
beneficial with the more traditional turbine type impellers for
certain applications.

remains stationary while
impellers on the stirring shaft and
baffles outside of the basket
direct the flow of reactants over
the surface of the contained

entrainment impeller provides a
uniform flow of both gas and
liquid over the fixed catalyst bed
held within the annular basket.
The Parr design for these baskets
includes a rigid bottom support
which permits high speed stirring
without excessive vibration.
Cooling coils, internal temperature measurements and liquid
and gas sampling operations can
be continued as usual without
interference from the installed
catalyst basket.
Reactors and Pressure Vessels — Optional Fittings
In the dynamic design the
catalyst is held in an annular
shaped, mesh basket which is
attached to the stirrer drive in
place of the stirring shaft. The
rotating basket then serves as an
impeller for stirring the reactants.
Fixed baffles and coaxial
impellers ensure good circulation
over the surface of the contained
catalyst. The dynamic baskets
are available for reactors with
volumes of 1000, 1800 and
2000 mL. Dynamic baskets must
be installed in reactors equipped
with at least 1/4 hp motors to
ensure that sufficient stirrer
torque and speeds are available
for proper operation. Dynamic
baskets are interchangeable

condensers for
attachment to the head
of a stirred reactor or pressure
vessel. These can be made in
various sizes to match the size
of the reactor.
P
Straight Reflux
Condenser
The standard reflux condenser
consists of a length of tubing
connected directly to the head of
a vessel and equipped with a
water cooling jacket. Condensed
vapors are returned directly to
the vessel and any noncondensable gases can be released
through a needle valve at the top
of the condenser. A spiral wound
inner packing in the condenser
ensures maximum effectiveness
in a rather short length.
Reflux/Take-Off
Condensers
The standard reflux/take-off
condensers consist of a water
jacketed tube, the same as
described above, assembled with
a receiving vessel attached to the
lower end of the condenser. Any
vapor, such as water from a
polymerization reaction, can be
condensed and collected in the
receiver, from which it can be
withdrawn from a bottom valve.
Any noncondensable gases can
be released through a needle
valve at the top of the condenser.
If condensate collection is not
required, the receiver can be
removed and the condenser can
be mounted directly above the
reactor for direct reflux into the
vessel.

Safety Rupture Discs
he safety rupture discs in all Parr
reactors and pressure vessels are
made of Alloy 600 unless a
different material is specified. Alloy 600
is the preferred material for this
purpose because its burst pressure is
not significantly effected by the operating temperature, and its broad
corrosion resistance. Although these
discs will resist many chemical vapors,
they will be attacked to varying degrees
by strong mineral acids, strong organic
acids and wet halogens. Additional
protection can be secured by using a
gold-faced disc. Discs made of other
materials can be furnished on special
order. The rupture disc installed on any
Parr vessel should not be subjected to
pressures beyond approximately 70
percent of its rating during normal operations. If stressed beyond this point, the
disc may weaken and fail. For reactors
that must be operated up to their full
design pressure, Parr offers scored
rupture discs which can be used
repeatedly to 90 percent of their
designed burst pressure. These discs
are available on special order and are
significantly more expensive than the
standard discs.
All Parr reactors and pressure vessels
in small sizes up to and including
2 liters use 1/2 inch diameter rupture
discs in assemblies having a 1/4 inch
diameter orifice. 1 gallon and larger
vessels use a 15/16 inch diameter

relief valves can be added to a
reactor or vessel to:
• Relieve pressures near the
operating pressure.
• Reseal once excess pressure
has been relieved.
• Protect low pressure components at pressures below
available rupture disc ranges.
The relief valves listed below
can be installed on any Parr
vessel. These valves are stainless

Users are invited to contact the Parr
Technical Support Staff with any
requirements for special rupture discs
and are reminded that rupture discs for
Parr equipment must be matched to the
range of the pressure gage, and must
carry a rating higher than the intended
maximum working pressure.
In general, the 1000 psi shown for
the 1/4 inch orifice and the 600 psi
shown for the 1/2 inch orifice are the
minimum burst pressures available
without going to more temperature
sensitive and less corrosion resistant
materials of construction. When gages
are installed on one of these reactors
with ranges below these values, Parr
will install a spring-loaded relief valve
to protect the gage in addition to the
rupture disc which is the primary safety
device for the vessel.

Cooling Coils
nternal cooling coils are
available for all but the
smallest Parr reactors. These
coils provide an extremely
effective means of removing heat
from the vessel to control an
exothermic reaction or for
cooling the reactor at the end of a
test. Since heat is transferred
through the relatively thin wall of
the coil instead of the thick wall
of the vessel, cooling rates are
generally much faster than
heating rates; particularly at
temperatures above 80˚ C. Water
is normally used as the cooling
medium although compressed
air can be used for modest
cooling loads.
Cooling coils are offered in
three standard configurations:
Single Loop - Single loop
coils consist of the vertical runs
of tubing formed into a “hairpin”
shape. These are normally
installed on small reactors with

Alloy 400 gages are available on special order.
Accuracy is 1/2 percent for the 4-1/2 inch size
and 1 percent for the 3-1/2 inch gages. All are
calibrated in both pounds per square inch (psi)
and bars. Gages in Pascal units are available on
special order. Compound gages which show
vacuum to 30 inches of Mercury and positive
pressures to 300 psi/20 bar are also available
on special order.
When ordering a special gage, specify
the gage diameter, the desired range and
scale units.
The gage on a pressure vessel should be
150 percent of the maximum operating
pressure. This allows the gage to operate in
the most accurate pressure range and prevents
the gage from being stressed to its full range,
effecting the calibration.

Parr has developed a unique device
for adding small amounts of solids (or

within a reactor. It is of particular
interest to users performing kinetic
studies of catalytic reactions. It consists
of a small metal vessel with a male
nipple which screws into the underside
of the reactor head, and a full opening,
“trap door” plug with an O-ring seal at
the bottom of the vessel. To discharge
the contents of the holder, gas pressure
is applied through a valve on the
outside of the reactor. When the applied
pressure is greater than the pressure
within the reactor, the trap door will be
blown open and the catalyst or other
contents of the holder will be released
into the reactor. This device works best
in the taller, 450 mL and 600 mL Mini
Reactors, and in the 1 liter and larger

Bottom Drain Valves
ottom drain valves can
be added to many Parr
reactors. These valves are
particularly useful for those
working with polymers or other
material that must be discharged
from the reactor while they are
still hot and before they can
solidify. They are also quite
useful for the 1 gallon and larger
vessels which are too large to
conveniently lift from the heater
for product recovery. At the other
end of the spectrum, bottom
valves are rarely installed on the
micro and mini reactors with
their small volumes and light
vessel weights.
The standard bottom drain
valve is a rising stem, process
B
sampling valve. In the closed
position the stem of the valve is
flush with the inside bottom of
the vessel so that there is no
dead space between the bottom
of the vessel and the shut off
point of the valve. In the open
position the stem is retracted
completely to open a clear
passage from the vessel 3/8 inch
(9mm) or larger in diameter.
When the valve is reclosed, any
material in this passage will be
pushed back into the reactor by
the rising stem.
These valves will withstand
the full operating pressures and
temperatures of the vessels in
which they are installed. A high
pressure/high temperature
version is also available. Bottom
drain valves are available in sizes
larger than 3/8 inch on special
order. They are available in
nearly all of the current Parr
materials of construction. Air
actuated valves are available for
larger reactors. Users can also
specify that a reactor ordered
with a bottom valve shall have
a conical bottom, usually
15 degrees, so that it will drain
easily through the valve opening.
Not all Parr reactors will accept
a bottom drain valve. Since the
valve extends approximately
8 inches below the bottom of the
vessel, the entire vessel must be
raised by this amount to accommodate the valve. This converts
some models into a system that
is too tall for convenient bench
top operation. The specification
tables for each model will identify
those reactors in which a bottom
drain can be readily installed, and
those which will not accept a
bottom drain, or those which will
require custom modification of
the heater and support stand to
accommodate a bottom valve.

Needle valves and ball valves
can also be installed as bottom

generally used on the smaller
reactors. While ball valves can
also open large discharge

generally leave a fairly large dead

Safety
Check Valves
Windows
henever gases or liquids
are introduced into a
vessel under pressure,
the supply pressure must be
greater than the pressure in the
vessel to prevent reverse flow
back into the supply system.
Protection against reverse flow
can be obtained by installing a
check valve in the supply line.
With a check valve in the line,
the valve will snap shut if the
supply pressure is too low, or if
the pressure in the vessel should
rise above the supply pressure.
This protection is particularly
important on stirred reactors
where gas enters through a dip
tube. With liquids in the vessel,
any back pressure will force
liquid back into the gas tank or
into the gas supply system.
Parr stocks the poppet check
valves listed below for incorporation into the user’s supply lines.
These valves have a 10 psi normal
cracking pressure and are rated
for 3000 psi maximum working
pressures. Check valves with other
specifications can be furnished

indows can be installed

the maximum operating temperature to 200 or 250˚ C, depending
upon the O-ring material. Pressure
ratings range from 2000 to 3000

A
Transducer Glands
Transducer glands are used for applications requiring a number
of small insulated wires in a single gland. Wire sizes from 14 to 24
gage are used to carry small currents and voltages in the millivolt
range. A unique feature of this design is that multiple wires
(up to 16) can be individually insulated through a single gland.

These glands have a single conductor (or electrode) in sizes
from 0.093 to 0.312 inches in diameter, with the ends of the
conductor threaded so that internal and external lead wires can
easily be attached.
Power Leads
Power leads can be provided with either single or multiple flexible
wires in sizes from 14 to 18 gage. Current ratings range from 5 to 20
amperes at up to 600 volts. Either PTFE or ceramic insulation is
available. Ceramic glands can be used to the full temperature

installations must be carefully developed in consultation with the
user, the electrode or probe supplier and the Parr Engineering
Department. Glass electrodes with O-ring seals will obviously carry
rather severe temperature and pressure restrictions. There are also
space restrictions which generally dictate that accessories of this
type can only be installed in 1000 mL or larger vessels.

Temperature
Limits/Extreme
Temperature
Systems
Extremely Heated
Vessels
There are a number of factors
that determine the maximum
temperature rating of a pressure
vessel. For most applications it is
the gasket material. Vessels with
O-ring seals are limited to 225˚ C
unless exotic materials are used to
extend this temperature to 300˚ C.
Parr’s design for contained PTFE
gaskets extends the operating
temperature range to 350˚ C.
Flexible Graphite (FG) material
essentially removes the gasket as
the limiting factor. It has been used
to 6000˚ C well above any practical
pressure vessel application.
Maximum temperature limits for
the metals used in these vessels
are established by the ASME and
other standards. Most metals have
maximum temperature limits
between 400 and 800˚ C. The
allowable strength for these
metals falls off rapidly as they
reach maximum operating temperature. Finally, the difficulties
encountered with screw threads
and other closure components
operating at high temperatures
establish a practical temperature
limit for externally heated vessels.
We have found 600˚ C to be
the limit.
Internally Heated
Vessels
Another approach has proven
useful in extending the maximum
temperature limit. In this design the
heater or furnace is placed inside
the pressure vessel. This heater is
surrounded by a layer of insulation.
This creates a hot zone in the
center of the vessel and
prevents the walls from
➥
Optional
Fittings
➥
External Valves,
Gages and Fittings
exceeding their allowable limit.
Properly designed, temperatures as
high as 1200˚ C are generated in the
core of the vessel while the walls
remain below 250˚ C. This system is
very energy efficient. Internal
heaters can be less powerful than
external heaters. Internally heated
vessels are equipped with insulated
electrical feed throughs to power
the heater and multiple thermocouples to monitor and control the
temperatures in the hot zone and
the vessel inner wall.
The reactions or studies carried
out in internally heated vessels
must be limited to those which will
not destroy the exposed internal
heaters and insulation. These are
normally gas-solid reactions or
controlled atmosphere heat
treatment studies. The heating
elements are normally ceramic.
Some users have developed
induction style heaters and
insulators and have extended their
investigations to above 2500˚ C.
Although internal heaters can be
installed in almost any non-stirred
Parr pressure vessel the 1.8 liter,
Model 4683 High Pressure/High
Temperature vessel is an excellent
starting point. It can accommodate
a cylindrical, insulated heater
1-3/4 inch diameter by 8 inch
deep, capable of producing and
sustaining internal temperatures
to 1200˚ C.
Internally heated vessels have
also been produced using cartridge
type heating elements inserted in
specially designed “thermowells”.
These wells protect the heater
from the reactants and expand the
applications that can be studied.
Cartridge type heaters have a
maximum temperature of 850˚ C.
Materials of
Construction
Unless specified, the valves, gage,
magnetic drive and other external parts
on Parr reactors are furnished in stainless
steel, even when a different material is
specified for the cylinder, head and
internal wetted parts. These parts are less
expensive than if made of a special
material and, in most cases they can be
used with complete satisfaction, since
they are in contact only with the vapor
phase and not with liquids in the reactor,
and they are air cooled and normally at a
lower temperature than the internal
components. But, if external parts made
of a material other than stainless steel
are required for safety or other reasons,
they can be furnished if available.
Any request for external parts made of
a specific material must be stated
clearly when ordering.
Valves
Most reactor valves are available in
Alloy 400 as well as stainless steel at a
reasonable cost premium. Valves made of
Alloy C-276 are also available, but
generally only on special designs and at a
considerable cost premium. Soft materials
such as titanium and zirconium generally
make poor performing valves.
Gages
Pressure gages are available in
Alloy 400 and stainless steel, but other
materials of construction are not
available. The standard method for
protecting the gage in a corrosive
environment is to install a diaphragm
gage protector. These have a flexible
diaphragm which isolates the gage from
the reactants and a sealed hydraulic
connection for pressure transfer to the
gage. These assembles are too large to
install on all but the largest Parr reactors.
3
As an alternative, Parr has designed an
oil filled piston isolator gage protector to
isolate the gage on small reactors and
pressure vessels where space is limited.
These isolators can be furnished in any of
the current Parr materials of construction,
with an attached cooling jacket.
Pressure Transducers
Pressure transducers are only available
in stainless steel. Parr provides a
mounting adapter with a water cooling
jacket on pressure transducers to protect
them from excessive temperatures. These
can be replaced with piston style isolators
similar to gage protectors when corrosion
resistance is required. When a gage and a
pressure transducer are installed, a single
isolator can protect both.
Magnetic Drives
Magnetic drives can be furnished in all
of the current Parr materials of
construction except nickel. These drives
represent a significant portion of the cost
of the reactor and the price premium for
special alloy construction is fairly low.
Specifying a magnetic drive of the same
material of construction as the wetted
parts is generally a wise choice.
Valve and Gage
Adapters
These fittings are available in the
current Parr materials of construction but
must be specified when ordering.
Rupture Discs
The standard material of construction
for rupture discs is Alloy 600. A gold
facing is available for the smaller discs
used on vessels up through 2 liters in
volume. Alloy C-276, Tantalum and other
premium materials are available on

arr Instrument Company
is pleased to work with
customers in the design
and assembly of complete
laboratory or pilot plant reactor
systems, offering a full spectrum
of reactor designs, ranging from
simple, Stirred Tank Reactors for
batch operation to Continuous
Flow Stirred Tank and Tubular
Systems. Parr can furnish either
the essential components for
assembly by the user, or a
completely assembled turnkey
system. Parr’s experience in this
field has ranged from table-top
micro systems to small operating
pilot plants, each with a reactor
(or reactors) designed to meet
the user’s particular requirements. Our experience in systems
includes:
P
Continuous Flow
Stirred Tank
Reactor Systems
This mode of operation
requires that reactants be introduced and products removed on
a continuous basis. Generally,
this must be done with the
reactor at elevated temperatures
and pressures. Reactors used for
these applications must be
modified to provide sufficient
inlets and outlets for the reactants and products as well as
designs for maintaining
continuous operating levels and
pressures under flow conditions.
Continuous Flow
Tubular Reactor
Systems
Instead of a stirred tank reactor
these systems use a tubular
84
Reactors and Pressure Vessels — Optional Fittings
vessel generally packed with a
fixed bed of catalyst. Reactant
liquids and gasses are fed to the
reactor at a controlled rate
through preheaters and mixing
systems. Products are collected
from the discharge of the
reactors and are cooled and
separated for recovery.
Reactor Support
Systems
Both stirred tank and tubular
flow reactors will require feed
and recovery systems when
operated in a continuous
flow mode. Subsystems and
components developed for
incorporation into these
systems include:
Gas Feed Systems
These systems commonly
include one or more of the
following components:
Intermediate Reservoirs.
These gas supply tanks can be
sized to the expected
consumption of the reaction so
that the pressure drop in this
reservoir can be measured to
determine total consumption by
the reactor. If the pressure is
measured continuously, the rate
of pressure drop can be
converted to reaction rates.
Constant Pressure Gas
Regulators. These regulators,
sometimes called forward
pressure regulators, will deliver
gas to a reaction to maintain a
constant pressure within the
reactor. They are a simple and
effective means for controlling
the pressure in systems where it
is desirable to feed

non-flowing reactor over time.
Electronic Mass Flow
Meters. These meters will
measure the flow rates of gases
into a reactor. They are very
valuable for systems under
integrated computer control.
Electronic Mass Flow
Controllers. These are electronic
flow meters with an added flow
control valve which delivers the
flow at a constant rate which can
be set by the user.
Back Pressure Regulators.
These regulators are generally
installed on the gas discharge
line of a reactor to maintain the
desired pressure within the
reactor by regulating the flow of
exit gases. They can be set either
manually, or by gas pressure, or
electronically, as required. These
back pressure regulators are
commonly used with mass flow
controllers to ensure that the flow
of gas passing through a reactor
has been held at a
constant pressure.
vessel is pressurized with
nitrogen (or other gas) to a
pressure greater than that in the
reactor, and the liquid is fed into
the reactor through an appropriate control valve. This
arrangement is usually selected
for systems in which liquid is
introduced as a batch rather than
continuously. A liquid level indicator or sight glass can be added
to provide some degree of
measurement and control.
Liquid Feed Pumps. A
variety of liquid feed pumps are
available, but the most
commonly used ones for Parr
reactors are those designed for
high pressure liquid chromatography. These small pumps have
available flow
rates and operating pressure
ranges well
suited to Parr
reactor systems.
Chemical feed pumps are also
available for larger systems.
Product Handling
Systems
The following components are
commonly employed to deal with
the hot, high pressure product
streams leaving a reactor.
Cooling Condensers. These
can be used in various ways: to
separate and return condensable
solvents to the reactor from the
exhaust stream; to take off
condensable liquids; to cool
exhaust gases before they reach
a back pressure regulator; or to
cool a liquid product. Many
different sizes and configurations
are available.
➥
Liquid Feed
Systems
There are two
commonly used liquid
feed systems:
Pressure Pipette
Assemblies. These
generally consist of a
small pressure vessel
from which liquid feed
material can be forced
into a reactor. The

Gas/Liquid Separators.
These are generally recovery
vessels which receive a mixed
flow of gasses and liquids and
separate them for appropriate
recovery or venting. Often they
are equipped with coolers and/or
reflux condensers.
Liquid Level Control
Systems. At high pressures and
temperatures in small systems,
liquid levels are most practically
controlled by stand pipes or
discharge level controls rather
than by electronic controls. While
some electronic controls are
available, they are not always
small enough or sensitive to the
small level changes experienced
in bench scale and small pilot
plant systems. Pressure and/or
temperature ratings may also
be inadequate for a particular
installation.
System Integration

Integrated Support Stands.
Support structures for the
reaction vessel and its various
subsystems can be designed and
fabricated to provide systems
which are ready to install in the
user’s spaces.

Overview
Temperature Controllers
4842 Temperature Controller with Expansion Options
icroprocessor technology has brought
dramatic improvements to the field of temperature control in recent years.
Yesterday’s on/off and current
proportioning controllers have
been replaced with entry level
controllers with PID.
M
PID Control
PID (Proportional - Integral Derivative) control can rapidly
bring a system to a desired
temperature with little or no
overshoot and smooth,
continuous regulation. These
controllers are now self-tuning
so that they can set the proportional band, compensate for
any offset and adjust the
proportional action to ensure
90
4861 Process Controller with 4855 Slave Box
that the temperature in the
controlled system will be held
at the set point with minimal
deviation.
Prior to the advent of these
modern controllers, heating
baths, block heaters, special
thermocouple placements and
similar hardware and techniques were required to
produce acceptable control for
many applications. But with the
anticipatory and adaptive
nature of these modern
controls, special heaters and
special control systems are
now reserved for only the most
unusual and difficult control
applications.
Three additional levels of
control can be added to the
basic level of PID control.
Reactors and Pressure Vessels — Controllers
Ramp and Soak
Programming
This control option allows
the operator to program a time
and temperature profile into the
controller for the controller to
follow automatically. This can
consist of a series of different
temperature settings and the
length of time each is to be
held. The rate of change from
one setting to another can also
be controlled if the changes are
within the capability of the
heating and/or cooling system.
An additional feature provides
for control of the approach to
a critical temperature when
over-shoots cannot be
tolerated. A visual display
prompts for all programming
and timing functions.

Overview
➥
Cascade Control
This control option utilizes
two temperature sensors: One
internal and one external to
provide superior performance
in difficult control systems. It is
particularly effective for heating
systems with large thermal
lags, such as thick wall vessels
or vessels with glass or PTFE
liners, also for systems where
the contents of the vessel
have a small heat capacity
when compared with the
vessel itself. By monitoring
both the internal and external
temperatures a cascade
controller prevents the external
temperature from exceeding
the internal temperature by a
margin large enough to induce
significant over-shoots.
Separate Heating
and Cooling
Control Loops
Parr controllers actually
have two separate PID control
loops; one for heating and a
second one for cooling.
The second loop with its own
self-tuning parameters can be
used to activate a solenoid
valve to control the flow of
coolant through an installed
cooling coil.
Temperature Control Profiles Offered by Series 4840
and 4860 Temperature Controllers
On-Off Control
This is the simplest control mode.
Power is turned on and off as the
temperature passes through the set point.
This results in wide cycles above and
below the set temperature.
PID Control
Proportional-Integral-Derivative
Systems have three control functions.
Proportional control adjusts the heating in
proportion to the temperature difference
from the set point. Integral function
compensates for any temperature control
offset from the set point. The derivative
function deals with the rate of change of the
temperature.
Ramp and Soak Control
Ramp programming allows the
operator to program a time segment
together with an initial and final
temperature. When the beginning and
ending temperatures are the same, it is
referred to as a soak. Individual segments
can be linked together to produce a
programmed profile.
Cascade Control
Cascade control utilizes both internal
and external temperature inputs to control
systems with unusual temperature lags or
imbalances to minimize initial overshoots
and subsequent cycling of the controlled
temperature.

Tachometer
Display Module
This module provides a
means for continuously
monitoring the stirring
speed in Parr reactors,
offering a particularly
valuable feature for units
equipped with variable
speed motors. It consists of a
bright digital readout to be
installed in the controller cabinet
and connected to an optical
tachometer mounted on the
stirrer drive shaft in the
reactor. The digital
display will show the
stirring speed with 1 rpm
resolution and +/- 5 rpm
accuracy. When ordering
this option for field installation
be sure to provide the model
number and serial number of
the reactor on which the
tachometer is to be installed so
that the proper hardware can
be furnished.
Option 2—PDM
Pressure Display
and Cut-off
Module
This module provides a digital
readout for continuously monitoring the pressure within the
reactor, plus a back-up safety
feature which will shut down the
system if a pre-set maximum
pressure is reached. Pressure is
displayed with 1 psi resolution
and 10 psi accuracy on a bright
LED digital readout, normally
calibrated from 0 to 2500 psig.
Higher or lower ranges are
available by special order. The
safety cut-out feature offers
excellent protection against accidental over-pressurization by
allowing the user to set a
maximum pressure which, if
reached, will activate a lock out
relay and shut down the system
immediately.
The signal for the pressure
display is generated by a
transducer in a stainless steel
housing mounted on the reactor
near the Bourdon tube pressure
gage. For applications involving
environments corrosive to
stainless steel, users should
consult with the Parr engineering staff regarding possible
corrosion protection arrangements. When ordering this
option separately or installed in
a Series 4840 Controller, always
specify the reactor on which the
Reactors and Pressure Vessels — Controllers
transducer will be installed so
that the proper hardware can
be furnished.
Option 3—HTM
High Temperature
Cut-off Module
This module provides a
completely redundant high
temperature safety cut-off which
will shut down a reactor in case
of an unusual malfunction in the
primary control system. Each
Series 4840 Controller has a
high temperature safety cut-off
built into the control system, but
this feature depends upon the
proper functioning of the
sensing thermocouple and the
temperature measuring circuitry.
To guard against any possible
malfunction in this primary
system, the optional high
temperature cut-off module
offers a completely independent
secondary (on/off) controller
operating with its own thermocouple, digital display and
wiring, which will shut down the
system if a pre-set maximum
temperature is reached.
When used with any Parr
micro or mini reactor, this
module requires a dual thermocouple consisting of two thermocouples sealed within a
single sheath and installed in the
single thermocouple opening.
For all other Parr reactors the
module operates from a second
thermocouple inserted into the
thermowell together with the
basic control thermocouple.
When ordering this option separately or installed in a Series
4840 Controller, always
specify the reactor on
➥
Controllers
Series 4840
Modular Controllers
➥
which it will be used so that a
thermocouple of the proper style
and length can be furnished.
Option 4—AMM
Ammeter Display
Module
This module provides a
means for continuously monitoring the current being drawn
by the stirrer motor. Since the
motor speed control will provide
a constant stirring speed at any
given setting, changes in the
current drawn by the motor will
correspond to changes in the
viscosity of the reactants in the
vessel. This will be a useful
option for users who want to
monitor the progress of a polymerization reaction in which
there is a viscosity change as
the reaction proceeds.
Option 5—(A)
Analog Outputs
Analog outputs for recording
the measured data are available
for the tachometer, pressure,
high temperature and ammeter
modules. Dual ranges are
provided in each output, giving
the user a choice of either a
0-5 volt, 0-10 volt, or a 4-20 mA
linear signal. If this feature is
desired, it must be specified
when ordering any of the
above modules.
Option 6—CM
Communications
Module
This option is available for the
primary temperature controllers.
It adds a RS232C communications port to only the primary
temperature control module
4
within the controller. This digital
communications link can be
used to set or change all parameters within the temperature
control module and to transmit
the temperature to an attached
computer. It does not communicate with any of the expansion
modules (tachometer, pressure
display, ammeter or high
temperature cut-off) which may
be installed in the controller.
Analog outputs can be provided
for users who wish to record the
data from these additional
modules.
Option 7—SVM
Solenoid Valve
Module
This module provides
solenoid valves and all parts
needed to assemble an automatic flow control system for
controlling the flow of coolant
through a cooling coil in any
reactor. It usually is installed in a
cold water line with a flow
connection to the cooling coil
and an electrical connection to
an output socket provided at the
back of the temperature
controller. This connection is
driven by its own PID control
loop. This system is particularly
advantageous for controlling
exothermic reactions or holding
temperatures below 150˚ C.
Parr can also furnish controllers made by other
manufacturers if a user has a preference for a
particular brand, or if he requires a controller with
special functions not available in a Parr unit.
Inquiries are always welcome.

Four of the five
analog inputs have
24-bit analog to digital
converters to provide at least 1
ppm resolution for high
precision applications. One
input is reserved to provide
cold junction compensation for
thermocouple inputs.
Appropriate signal conditioning
protection is provided for each
channel.
All of the above descriptions
apply also to the Model 4862
Controller, but with eleven input
channels instead of five.
Digital Inputs and Outputs
Both Model 4861 and Model
4862 Controllers have eight
digital input or output channels.
When configured as inputs they
can sense that interlocks are
closed, that doors or safety
devices are in their proper
positions, that purge systems
are on or they can monitor the
status of valves, pumps or other
auxiliary equipment. When
configured as outputs they
can activate auxiliary alarms
or equipment such as valves
and pumps.
Tachometer Inputs
Both Model 4861
and the Model 4862
Controllers have two
channels for
tachometer inputs.
These are used in
conjunction with the
tachometer sensors
mounted on the stirrer
drive mechanism of
the controlled
reactors. These
channels are in addition to the
analog inputs described above.
Analog Outputs
The Model 4861 Controller
has two analog output
channels. These can be
configured as either 4-20mA
current loops, or as voltage
outputs. High resolution, 16-bit,
digital to analog converters are
provided for each analog
output channel. These outputs
can be used to control
peripheral devices, such as
process valves, mass flow
controllers, and pumps as well
as to provide signals to strip
chart or other recorders. In the
Model 4862 Controller the
number of available analog
output channels is increased
to four.
Pulse Width Modulated
(PWM) Outputs
There are four pulse width
modulated (PWM) outputs on
the Model 4861 Controller and
eight on the Model 4862
Controller. These provide PID
control for heaters and any
other devices requiring PID
regulation. An installed halfpower feature makes it possible
to tune a heater to a lower
output by reducing its wattage
by one-half, if desired.
Motor Speed Controls
Both the Model 4861 and
Model 4862 Controllers have
two channels of DC motor
speed control. These channels
drive the Parr DC motor speed
controllers incorporated into the
reactor slave boxes.
Motor Current Inputs
Both Model 4861 and Model
4862 Controllers have two
inputs dedicated to measuring
the current draw of attached
DC motors. The motor speed

control circuitry is designed to
drive the motors at constant
speeds. Changes in viscosity
will change the load on the
motor and hence the current
consumption of the motor.
Users will be able to correlate
the motor current consumption
to the viscosity and, for
example, the degree of
polymerization of a reaction.
Communication Ports
Both Model 4861 and 4862
Controllers have three
serial (RS-232) ports,
➥

one of which is used
for communication
with the host computer or
terminal. One serves as a
printer port which can be used
to record or report data
collected by the controller. The
third port can be used to
connect serial devices, such as
a laboratory balance or other
“smart” peripheral device to
the controller.
Modular Construction
Modular construction is used
in the Series 4860 Controllers to
make it easy to adapt these
versatile controllers to a wide
variety of heater loads, stirrer
motor sizes, multiple zone
heaters, and different reactor
configurations. This also keeps
the high current loads and heat
generated by the solid state
control relays away from the
sensitive microprocessor
circuitry. The motor controls,
the load handling solid state
relays for heaters, and the
solenoid valves for cooling are
mounted in a separate slave
box. One slave box is included
with each 4861 and 4862
Controller.
4860
Ordering Guide
A composite identification number is to be used when ordering any Series
4860 Controller. The number is developed by combining the catalog number
from Table I with a set of letters from Table II that identify the analog signal
connection modules to be installed in the controller.
EXAMPLE
For example a 4861 Controller with five analog input channels equipped with:
• A JCM module for a Type J thermocouple for primary control
• A JCM module for a Type J thermocouple for controlling the maximum
vessel wall temperature
• A PSM module for a strain gage pressure transducer
• All operating from a 115V 60Hz power supply, would be listed as:
4861EB - JCM - JCM - PSM
In this example no signal conditioning module would be installed in the
fourth and fifth analog input channels.
A 4865 Slave Box will be furnished with each Series 4860 Controller to
provide a 25 AMP load relay for controlling a heater, a 1 AMP relay for cooling
control and a speed controller for a DC motor up to 1 hp. Users who wish to
control two reactors or operate multiple zone heaters must purchase an additional slave box for the second reactor and any additional heater zones.
Thermocouples, pressure transducers and other analog sensors and their
connection cables to the controller are not included since these come in a
variety of sizes and ranges and must be ordered separately.

he Series 4676, 20 Liter
vessels with a 9-1/2 inch
inside diameter are the
largest non-stirred pressure
vessels in the Parr line. Vessels
of this size are almost always
made to order for individual
applications. The 10 liter
vessels (Nos. 4678 and 4679)
establish what we believe is a
logical intermediate size
between the 7.5 liter (2 gal.)
vessels in the 4660 Series and
the larger, 18.5 liter (5 gal.)
vessels listed here. A number of
vessels in other sizes have been
produced within the 5 gallon
maximum size range.
Specifications for each of the
two Series 4676 vessel sizes are
listed with two different head
styles: a blank head and a head
with valves and gage. The
“valves and gage” head is fitted
with separate inlet and outlet
valves, a pressure gage, a
1/2 inch diameter safety rupture
disc and a thermowell sized to

4676 General Purpose, 18.5 Liter with Heater, and 4842 Temperature Controller
the depth of the vessel. The
other option, a blank head,
simply serves as a starting
point for a customized
assembly. Inlet and outlet
valves, safety ruptures discs,
thermowells, dip tubes, electrical leads and other fittings
can be added to adapt these
vessels to a user’s needs.
The Series 4676 vessels are
non-stirred versions of the
Reactors and Pressure Vessels — Non-Stirred Reactors
vessels used in the 5 gallon,
Series 4555 Stirred Reactors,
and they are normally furnished
with a support stand, lift system
and heater options designed for
the stirred reactor. All of the
4676 vessels have split ring
closures with either PTFE or
flexible graphite flat gaskets.
Vessels with the same
outside dimensions as those in
the Series 4676 group have

The heavier construction
required for these high

designs reduces the internal
volume of the vessel to a value
somewhat less than the
nominal sizes. Inquiries for
these and other vessels within
the 18.5 Liter size range should
be directed to the Parr

hese are the smallest Parr
general purpose vessels
with a split-ring closure.
They are made in 125 mL and
200 mL sizes with a 1-1/2 inch
inside diameter and a high
depth to diameter ratio. They
are intended for users who
require a deep vessel with a
small volume, particularly for
tests involving long, slender
samples. It should be noted,
however, that if a user can
accept a vessel with a 2-1/2 inch
inside diameter as offered in
the 4760 Series, one of the 4760
vessels may be less expensive
than the smaller diameter, 4750
model because it is made in
larger quantities and in more
machinable configurations.
The Series 4750 vessels have
six cap screws in the split ring
sections which develop the
sealing force on a flat PTFE
gasket. They are available in all

because of the limited head

additional openings will find the

starting point.

These vessels have a flat PTFE or
flexible graphite gasket that is sealed
with a screw cap. Special wrenches
and bench sockets are offered for
tightening these closures. The screw
caps and bodies are made in brass
or alloy steel. The brass parts can be
used to 250° C and the steel closures
can be used to 300° C. The maximum
working pressure is 1700 psi (115

standard material of construction for
T
these small, inexpensive vessels is
Type 304 Stainless Steel, but they are
also available in all of the current
materials of construction Parr
provides.
There is room for a single opening
on the head of these vessels. This is
generally an “A” socket which will
accept a 4316 Gage Block Assembly.
Blank heads and heads with 1/8 inch
or 1/4 inch NPT female sockets are

hese are the smallest of Parr’s high

They have a 1 inch inside diameter
and offer volumes of 21 or 71 mL.
These vessels are closed with an alloy
steel screw cap which carries six cap screws
to develop the sealing force on a flat, flexible
graphite gasket. Interchangeable PTFE
gaskets are also available for users who
need the high pressure capabilities provided
by these vessels, but who do not need to
operate above 350° C. These vessels are
available in all of the standard materials
currently offered by Parr, although many of
these materials will restrict the maximum
pressures and temperatures available.
Because of their small size and the nature
of these vessels, they are normally heated in
a furnace or similar general purpose heating
device. When equipped with the standard
high strength steel screw cap, the maximum
temperature and pressure ratings will be
severely limited if the screw cap is heated
directly as well as the body of the vessel.
Special high temperature alloys are available
for users who wish to heat these vessels in a
furnace and take advantage of the full design,
temperature and pressure limits.
Only one head opening is available for
these vessels. It is designed to accept the

Gage Block Assemblies
arr gage block assemblies combine the functions of an inlet valve, a
pressure gage and a safety
rupture disc in a compact
assembly which can be
attached to the head of any
pressure vessel with a single
connecting tube. There is a
threaded socket in the block for
a gas connection with a
pressure hose or tubing using a
type “A” coned pressure fitting.
Coned fittings are also used on
the thick-walled tube which
connects the block to the
pressure vessel. The valve in
this assembly controls the gas
flow into the vessel and the
gage shows the pressure in the
vessel when the valve is closed.
An Alloy 600 rupture disc with a
burst rating matched to the
gage is installed in the block.
P
Two Sizes
These gage block assemblies
are made in two styles which
differ only in the size of the
pressure gage and the size of
the tube connection to the
pressure vessel. The smaller
4316 Gage Block Assembly
is usually furnished with a
3-1/2 inch diameter pressure
gage and has a 3 inch
connecting tube with type “A”
coned fitting. This assembly is
normally installed on smaller
pressure vessels where space
is limited.
The 4317 Gage Block
Assembly has a 4-1/2 inch
diameter gage and type “B”
coned fitting on a 3 inch
connecting tube. Longer tubes
can be furnished on special
order.
The gage block, connecting
tube and pressure gage on all
of these assemblies are
normally made of type 316
stainless steel, but they can
also be made of Alloy 400 on
special order.

Coned Pressure Fittings
age Blocks, pressure hoses and other parts that
are frequently removed from a pressure vessel
are attached with a coned, socket type
connector. The male segment of a coned fitting
consists of a sleeve with a left-hand thread screwed
onto a thick-walled tube, plus a compression nut to
complete the assembly. When screwed into a matching
socket these parts produce a rigid joint which will
remain tight over a wide temperature and pressure
range, yet the joint can be made and broken repeatedly
without destroying the sealing faces. No gasket or
sealing tape is required. These fittings have the added

Thermocouples
emperature measurements in Parr reactors
and pressure vessels are
made with Type J (ironconstantan) thermocouples in
sealed metal probes of different
lengths. These can be inserted
either into a thermowell
attached to the head of a
pressure vessel or, as in Parr
“Mini” reactors, the bare probe
can extend directly into the
cavity without using a thermowell. When used alone, a
1/8 inch NPT opening and an
A833HC thermocouple
connector are required to seal
the probe into the head of the
vessel.
A separable plug on the end
of each probe allows the thermocouple to remain permanently attached to the head so
that it can stay in place when
the head is removed from the
vessel. The connection to a Parr
temperature controller is made
with an A470E2 extension wire.
All probes have a 1/8 inch dia.,
type 316 stainless steel sheath
except those which are used
bare in special alloy reactors or
where special corrosion resistance is required.
When selecting a thermocouple, measure the depth of
the thermowell in which it will
be used and select a probe
approximately 4 inches

longer than the depth of the
well. This will provide sufficient
length so that a smooth
90-degree bend can be made
in the stem to permit a lateral
connection to the plug with
minimum interference with
other head fittings.
A472E Series thermocouples
are furnished only with a
stainless steel sheath. For
reactors made of materials
other than stainless steel, Parr
provides a thermowell made of
the same alloy as the vessel.
The stainless steel thermocouple is then installed in the
special alloy thermowell.

PTFE Lined Vessels
arr offers a broad
selection of PTFE lined
vessels for use in procedures involving highly corrosive
media. Although these vessels
are used primarily for
dissolving analytical samples in
strong mineral acids, they also
offer an attractive alternative to
metal pressure vessels for
procedures involving corrosive
media. They make excellent
containers for corrosion and/or
compatability tests at temperatures well above atmospheric
boiling points. Three of the
principal models are described
here. For additional designs and
P
technical information, please
refer to Parr Bulletin 4700.
Unique Parr
Designs
In each of these vessels the
charge is held in a thick-walled,
chemically resistant PTFE liner,
completely isolated from the
supporting metal body. To
maintain this arrangement
these vessels are only offered
as simple closed systems. No
valves, gages or other attachments which would require
penetration through the PTFE
liner are available. But each of
these vessels has a unique
safety blow-out feature
designed by Parr to protect the
vessel from unexpected overpressure.
While the broad chemical
resistance of PTFE is ideal for
this application, PTFE expands
and contracts more than
stainless steel when it is heated
and cooled, and it will flow
under pressure. To counteract
these tendencies, Parr PTFE
lined vessels have a unique
spring-loaded closure which
will continue to maintain
pressure on the liner seal
throughout the operating cycle.
