Transcript Lab Equipment1

Beaker
Stores larger volumes of liquids for mixing
Thermometer
Degree Celsius To measure the temp. of liquids
Bunsen burner
Heating of liquids and solids
Strikers
Strikers are used to light
Bunsen burners.
The flints on strikers are
expensive. Do not operate
the striker repeatedly just
to see the sparks!
Clay Triangle
holds crucible on iron ring above a Bunsen
burner
Crucible Tongs
handles hot crucibles
Crucible
contains solids to be heated to high temperatures
Erlenmeyer Flask
flask: contains larger amount of liquid for mixing
purposes
Erlenmeyer: triangular shaped flask
Forceps
picks up small or hot objects
Funnel
Used to transfer liquids.
Volumetric flask
Used to make
precise
concentrations
of solutions.
Pipette
Used to
transfer
liquids to
test tubes
or beakers
from a
common
container.
Graduated Cylinder
measures volume of
liquids
Mortar and Pestle
Mortar and pestle
(bowl)
(grinder)
grinds solids into
powder
Ring Stand
holds lab apparatus, such as
iron rings, with clamps
Scoopula
(Combination Spatula and
Spoon)
dips into bottles of solid chemicals to remove them without
contamination or contact
Spatulas
Spatulas are used to
dispense solid chemicals
from their containers.
Chemicals should never be
transferred with your
bare hands.
Stir Rod
For mixing chemicals
Test Tube Clamp
clamps test tube to ring stand
Test Tubes
13 x 100 mm test tubes
Ignition
tube
10 x 75 mm test tubes
Test Tube Holder
holds/carries a
single test tube
When hot
Test Tube Rack
holds test tubes
Test Tube Racks
Test tube racks are for holding and organizing test
tubes on the laboratory counter. Plastic racks may melt
in contact with very hot test tubes.
Wire Gauze
holds hot
beakers/fla
sks on iron
ring
Rubber Stoppers
Rubber stoppers are used to
close containers to avoid
spillage or contamination.
Containers should never be
heated when there is a
stopper in place.
Spot Plates
Spot plates are used when
we want to perform many
small scale reactions at one
time. We will use these
many times during the year.

Wash Bottle
A wash bottle has a spout
that delivers a wash
solution to a specific area.
Distilled water is the only
liquid that should be used
in a wash bottle.
Weighing Boat
Weighing boats are used to
weigh solids that will be
transferred to another vessel.
