volume of
liquids
accurately
Metric Ruler
• To measure the
lengths of solid
objects accurately
oC
thermometer
• To measure temperature accurately
magnifying glass
(hand lens)
• To make objects
appear larger than they
are
Bunsen burner
• To heat substances
(with a flame)
hot plate
• To heat substances using electricity,
not a flame.
Lighter
These strikers are
used to light lab
burners.
The flints on
strikers are
expensive. Do not
operate the striker
repeatedly just to
see the sparks!
ring stand
with clamp and ring
• To hold containers
away from a heat
source (such as fire)

Ring clamps connect
to a ringstand, and
provide a stable,
elevated platform for
a beaker to be heated.
Will also hold a clay
triangle and funnel
during filtering.
Ringstands and their Components
Wire Gauze
Wire gauze sits on
the iron ring to
provide a place to
stand a beaker.
On older wire gauze,
the white material
was asbestos –
currently it is a
ceramic.
Crucible with lid: heat small
samples
Crucible Triangle: Cradles
crucible to secure over a
flame
Crucible Tongs
For handling hot
crucibles; also used
to pick up other hot
objects - NOT to be
used for picking up
beakers!
test tube
• To hold liquids and
chemicals during
experiments
(investigations)
test tube
holder
• To hold test
tubes over
heat or away
from your
body
Disposable pipet
• To drop small amount of
liquids
forceps
• To pick up small items that you
should not touch
Erlenmeyer flask

estimate liquids
• NOT used to measure
substances accurately
Funnel
To pour liquids from
one container to
another without
spilling anything
stirring rod
• To mix chemicals
and hot liquids
together (like a
spoon)
Stirring Rod
Stir with this end.
The stirring rod is
used to:
a) manually stir
solutions;
b) assist in pouring
liquids; and
c) to transfer a
single drop of a
solution.
Rubber policeman
tip is used to remove
precipitates.
Spatula
Spatulas are used
to dispense solid
chemicals from
their containers.
Chemicals should
never be
transferred with
your bare hands.
tongs
• To pick up large objects that you
should not touch (e.g., hot
containers, flasks of acids, etc.)
safety goggles
• To protect eyes
against burns or cuts
test tube brush
• To clean the insides of test tubes
after investigations
test tube rack
• To hold test tubes
during an investigation.
(After cleaning, test
tubes can be placed
upside down to dry.)
Well Plate: small scale
reactions
Broken Glass Box and Trash Can
Broken Glass box to
dispose of any broken
glass, instead of the
trash can.
Trash Can to
dispose of paper
waste only!
Watch Glass
A watch glass is
used to hold a
small amount of
solid, such as the
product of a
reaction.
Can also be used
as a cover for an
evaporating dish
or beaker.
Evaporating Dish
The evaporating
dish is used for
heating stable
solid compounds
and elements, as
well as for
evaporating
nonvolatile
solutions.
Weighing Boat
Weighing boats are used to weigh solids
that will be transferred to another vessel.
We will also use squares of paper for this
purpose – throw them away after using.
Never put chemicals directly on the
balance scale – it leaves residue and can
harm the balance
Wash Bottle
Distilled

a water stream to a
specific area.
Distilled water is
the only liquid that

a wash bottle
Eyewash Station
The Eyewash is
located in the back of
the lab in my chemical
closed and under the
Safety Shower. You
will need to summons
me for assistance at
the Eyewash Station.
Push this handle to
turn on the water – it
will stay on until you
pull it to turn off.
Flush your eyes for 1520 minutes!

are found behind
the door, at the
door to my
chemical room
and at the back
left corner of the
lab stations.
