PFA Trace Analysis
BRAND Labware
BRAND trace analysis labware is
manufactured from high purity PFA (a
perfluoroalkoxy copolymer), which is
highly resistant to heat and chemical
contamination and has surface properties
that greatly simplify cleaning. Use this
labware for excellent results in ICP-MS,
production and storage of trace analysis
standards, isotope separations, sample
digestions and more.
With the increasing need in trace
analysis labs for ultralow concentration
determinations in the ng/g (ppb) and
pg/g (ppt) range, the use of PFA labware
has become more and more important.
Other materials, when not specially
treated, may be subject to interaction
between the vessel and the sample,
standards or reagents it contains. This
may cause incorrect results with modern
trace analysis instrumentation.
All BRAND PFA trace analysis labware
features visible, accurate, and permanent
graduations for precise measuring. PFA
Labware is suitable for sterilization using
heat, gas and chemical methods for
handling sensitive biological solutions.
Besides of high purity PFA products
BRAND also offers Technical GradePFA products which may contain a small
fraction of reprocessed PFA from our
production process.
Properties
Excellent Temperature Stability
BRAND PFA trace analysis labware
maintains its stability in temperatures from
-200 ºC to 260 ºC (-328 ºF to 500 ºF).
No Leachable Metals
PFA is manufactured without metals such
as calcium, aluminum, iron, magnesium,
nickel, copper, manganese or zinc. These
metals can leach into samples from other
containers and contaminate samples.
Simplified Cleaning
Conventional labware for trace analysis
requires time-consuming and expensive
cleaning. The hydrophobic and antiadhesive properties of the exceptionally
smooth-surfaced PFA labware simplify
the cleaning process, making it ideal for
trace analysis.
Superior Chemical Resistance
PFA is inert with most reagents, including
nitric and hydrochloric acid routinely used
in cleaning trace analysis labware. This
stability significantly reduces the risk of
crosscontamination.
Excellent Long-Term Stability
PFA containers often extend the stability
of low (ppb) concentration standards.
Such stability reduces the time and
cost of renewing trace analysis standard
solutions.
Highly Translucent
Translucency is important for making
accurate measurements using volumetric
labware.
A d v a n t a g e s o f P FA i n t r a c e a n a l y s i s
Scanning electron microscopy illustrates the advantages of PFA in trace analysis.
(Magnification: 8000X)
Bottle – HDPE
Beaker – PTFE
Scanning electron
microscopy of this
bottle wall shows
the roughness of
HDPE. The increased surface
area of HDPE can
lead to carryover of
reagents.
Evaporating
Similar to
dish – PFA
HDPE, electron
micrographs of
this beaker reveal
a typically rough
surface that can
interact with
reagents and
complicate cleaning.
Even at 8000x
magnification, the
surfaces of this PFA
evaporating dish
are very smooth. It
is this smoothness,
combined with
PFA’s hydrophobic,
anti-adhesive and
inert properties, that
simplify cleaning.
Dispensette ® Organic
The ideal supplement
As an ideal supplement we recommend the
Dispensette ® Organic.
Detailled information and leaflets can be downloaded
on www.brand.de or are available in printed form free
of charge.
■ The Dispensette ® Organic
(yellow color-code) is ideal for
dispensing of organic solvents including chlorinated
and fluorinated hydrocarbons
(e. g., trichlorotrifluoroethane
and dichloromethane), concentrated acids (e. g.,
fuming HCl and HNO 3 ),
trifluoroacetic acid (TFA),
tetrahydrofuran (THF) and
peroxides. For bases and saline solutions we recommend
the Dispensette ® III.
Dispensette® Organic
E A S Y C A L I B R AT I O N
■ The
flowpath
of
the
Dispensette ® Organic consists
of the following high-grade
materials: borosilicate glass,
ceramic, tantalum, ETFE, FEP
and PFA. The discharge tube
safety screw cap is PP.
■ Operating limits:
vapor pressure max. 500 mbar,
viscosity max. 500 mm 2 /s,
temperature max. 40 °C,
density max. 2.2 g/cm 3 .
