EXPERIMENT NO. 1
COMMON LABORATORY APPARATUS
INTRODUCTION
Familiarization with laboratory apparatus specially the common ones is very essential in
dealing with experiments in Chemistry. Every student should be able to identify not only the
materials and reagents necessary for an experiment but more importantly the apparatuses to
be used in the conduct of such activity.
OBJECTIVE
1. To identify the different laboratory apparatuses and their features.
2. To know the use of each of the apparatus and to be aware of the possible
replacement or substitute if an apparatus is not available.
PROCEDURE
1. On the table below, draw the apparatuses using pencil. You may have noticed that
they are grouped according to the material from which they are made of. Moreso,
they are arranged from the more common ones to the less common. This will
somehow help you to easily recall their names and forms. You may refer to Google
for the features of each of them.
2. Give the use of the apparatus on the column next to the drawing. If the apparatus
has multiple uses give at least two (2) of its uses. Again, you may refer to Google for
this part.
A. Glass
Apparatus
1. test tube
2. beaker
Use (s)
-Test tubes are widely used to
hold, mix, or heat small
quantities of solid or liquid
chemicals,
especially
for
qualitative experiments and
essays.
-Test tubes are also used as
collections devices for things
like blood samples
-Beakers are useful as a
reaction container or to hold
liquid or solid samples.
-They are also used to catch
liquids from titrations.
3. graduated
cylinder
-It is a common piece of
laboratory equipment used to
measure the volume of a
liquid. They are not intended
for mixing, stirring, and
heating unlike test tubes.
4. glass rod
-A glass stirring rod, or glass
rod is a piece of laboratory
equipment to mix chemicals.
-The glass rod can also be
divided into laboratory used
stirring rod and sight glass
used rod.
Drawing
5. erlenmeyer flask -They are also used to contain
liquids and for mixing, heating,
cooling, etc.
-It’s usually used in chemistry
experiments in order to mix
different chemicals or to
contain titrate of a solution.
6. florence flask
-Florence flasks are used as a
reaction vessel as well as for
heating solutions.
-It also used for distillation and
ease of swirling, and is
produced in a number of
different glass thicknesses to
stand different types of use.
7. laboratory
thermometer
-It is a thermometer used to
measure temperature with a
high level of precision for
applications,
such
as
experiment
monitoring,
instrument
calibration,
materials
testing,
and
maintaining a sterile work
environment.
8. alcohol lamp
-Alcohol lamp is generally
made up of glass, brass or
aluminum and it uses ethyl
alcohol or spirit as a fuel.
-It is used for heating,
sterilization, and combustion
in a laboratory.
9. funnel
-It is used to channel liquids or
fine-grained substances into
containers with a small
opening.
-Funnels are also used for
pouring liquids or powder
through a small opening and
for holding the filter paper in
filtration.
10. watch glass
-A watch glass is a round,
concave glass dish used for
evaporation in chemistry.
-And it can also be employed
for weighing solid and as a lid
for flasks and beakers.
11. reagent bottle
-Reagent bottles are intended
to contain chemicals in liquid
or
powder
form
for
laboratories and stored in
cabinets or on shelves.
-It is a special container for
various liquids and solid
reagents in the laboratory.
12. Pipette
-It is generally used for moving
small amounts of liquid or
when
measuring
and
dispensing liquid in mL units.
-Without this, the transfer of
liquids from one location to
another would be messy and
unsafe.
13. volumetric flask
-It is a lab glass or plasticware
used to prepare a solution. It is
used to make up a solution to
a known volume.
-Volumetric flasks are used to
measure volumes much more
precisely than beakers or
Erlenmeyer flasks.
14. distilling flask
15. separatory
funnel
16. condenser
-It is primarily used for
distillation, the process of
separating a mixture of liquids
with different boiling points
through
evaporation
and
condensation.
-It is also used to contain and
heat the liquid(s) that require
purification.
-Separatory funnels are used
in the lab for liquid-liquid
extractions,
separating
a
mixture’s components into two
solvent phases of different
densities.
-Condensers are employed in
power plants to condense
exhaust steam from turbines
and in refrigeration plants to
condense refrigerant vapors,
such as ammonia and
fluorinated hydrocarbons.
17. burette
-Burette is a laboratory
apparatus frequently used to
dispense
and
measure
variable amounts of liquid or
sometimes
gas
within
chemical and industrial testing
specially for the titration
process
in
volumetric
analysis.
18. thistle tube
-Glass thistle tubes are a
useful piece of glassware for
adding chemical solutions to a
reaction vessel.
-It also minimize the risk of
reaction occurring too quickly
and bubbling over.
B. Metal
Apparatus
1. test tube holder
Use (s)
-A test tube holder is used for
holding a test tube in place or
when the tube is hot and cannot
be touched
-It is also used to hold test tubes
while performing crucial chemical
reactions as it prevents the effect
of hazardous chemicals falling on
the body and skin
2. crucible tong
-It is used to grasp a hot
crucibles, flasks, evaporating
dishes, or even small beakers.
Drawing
3. triplebalance
beam -The triple beam balance is
used in a laboratory to
measure the mass directly
from the objects, find mass by
difference for liquid, and
measure out substances.
4. tripod
-It is used as a platform to hold
and support glassware, such
as beakers and flasks, during
experiments and when the
glassware is not in use.
5. wire gauze
-It is used and placed on the
support ring that is attached to
the resort stand between the
Bunsen burner and the
glassware to support the
beakers, flasks, or other
glassware during heating.
6. spatula
-It is also used to allow the
heat to be dispersed more
evenly.
-Spatulas are commonly used
to
transfer samples
or
chemicals from their original
containers to weighing paper,
weighing boats, weighing
bottles, weighing funnels, or
other vessels or containers for
weighing.
7. iron stand
-It is used to support the iron
ring when heating substances
or mixtures in a flask or beaker
(using a Bunsen burner)
clamps can also be used to
hold glasswares on the iron
ring.
8. iron ring
-Iron ring is used to support
flasks or funnels upright in a
stand. This is to enable the
stability of the flask of funnel
while
testing
is
being
performed.
9. universal clamp
10. cork borer
-It allows the ring stand to
provide support for other
equipment and a means of
raising equipment above the
work surface.
-It is a laboratory equipment
used to hold things and is
placed in an iron stand to
elevate other equipment such
as beakers.
-It is a tool that is often used
for cutting a hole in a cork or
rubber stopper to insert glass
tubing.
-It serves as a stopper
because it stops the flow of
compounds in the gas phase.
11. set of weights
-They are used to calibrate
certain lab equipment such as
electronic balances.
-They are also used for twopan balances which one
object is placed on one pan,
and weights are placed on the
other pan until the scale is
balanced.
C. Others (plastic, wood, rubber, marble, porcelain, or combination)
Apparatus
1. test tube brush
Use (s)
-These brushes are very
durable and have hog bristles
and a wire body and are used
for cleaning test tubes.
2. wash bottle
-Wash bottles primarily used
to wash or rinse various
pieces of glassware or
plasticware in the laboratory.
-They can also be filled and
used
as
storage
with
numerous solvents.
3. dropper
-Droppers are instruments
used for measuring and
transferring liquid in small
amounts.
Drawing
4. test tube rack
5. stopper
6. clay triangle
-Test tube racks are laboratory
equipment used to hold
upright multiple test tubes at
the same time.
-They are most commonly
used when various different
solutions are needed to work
with simultaneously, for safety
reasons, for safe storage of
test tubes, and to ease the
transport of multiple tubes.
-Laboratory stoppers are used
not only to prevent spills, but
also to trap noxious fumes or
to allow the vessel to be
shaken.
-It is a laboratory equipment
used in the process of heating
substances.
-It is also used in conjunction
with other lab equipment to
create a stable framework in
which to place a substance
that is usually a solid chemical
while it is heated to a high
temperature.
