Transcript Chemistry Lab Drawer Equipment

Common Chemistry Lab
Equipment
Chemistry Lab Drawer
Well Plate
 Used for “small scale” reactions, where
you are only using drops of solutions.

Chemistry Lab Drawer
 Micro
Spatula and Scoopula
 Used for measuring small amounts of
chemicals.
Scoops and Spoons
 Never
stick these directly into a bottle
of chemicals.
 You can contaminate the entire
bottle.
 This means that I will either have to
throw it away, or your lab results
could be affected.
Chemistry Lab Drawer
 Wash
bottle. Use this for “rinsing”
chemicals into your reaction vessel.
Chemistry Lab Drawer
 Test
Tube Rack and Test Tubes
 Test Tubes are another “primary”
reaction vessel
Chemistry Lab Drawer
 Graduated
Cylinder
Graduated Cylinders
Use these to accurately measure liquids in
lab. Never use beakers to measure.
 The answer on the SOL to this question is
always GRADUATED CYLINDER.
 Accurate to within ± 0.05 ml. (This is ½
of the smallest division line on the
cylinder.) Scientists call this the
“uncertainty” of the measurement.

Volumes.
We will work with liters (L) and milliliters
(mL) in this class.
 You should know that 1000 mL = 1L.
 Also know that cubic centimeters (cm3)
and milliliters (mL) are different names for
the same amount. So, 1 mL = 1 cm3.
 1 drop from a dropper is approximately
0.05 mL. So, 20 drops = 1 mL.

 Medicine
droppers
 We will primarily use plastic,
disposable droppers.

Chemistry Lab Drawer
 Glass
Funnel
 Used with filter paper.
Chemistry Lab Drawer
Beakers
Chemistry Lab Drawer
Evaporating Dish
 Used for GENTLE heating or NO heating

Chemistry Lab Drawer
 Wire
Triangle with Porcelain
 Use this when heating crucibles.
Chemistry Lab Drawer
 Ring
Stand and Clamps
 Ring Clamps and Utility Clamps
Chemistry Lab Drawer
 Wire
Gauze with Ceramic Center
 Use this for heating beakers or flasks.
Chemistry Lab Drawer
 Erlenmeyer
Flask
 Used as a reaction “vessel” in lab.
 Swirl
Chemistry Lab Drawer
 Bunsen
Burner
Bunsen Burner Safety
1. Never walk away from a lit burner.
 2. Never leave the gas turned on while
the burner is NOT lit.
 3. Never leave a test tube in the flame
while heating.
 4. Never point a test tube at someone
else while heating.

 Flint
Burner Lighter aka Striker
Chemistry Lab Drawer
 Pipets
and Pipet bulb
 NEVER use your mouth to pipet.
Pipets
Used for transferring solutions to a
reaction vessel. Transfer pipets are used
when accuracy isn’t absolutely necessary.
 Volumetric pipets are calibrated to deliver
an exact amount. Used when that is an
important factor in your experiment.

 Volumetric
flasks
Volumetric Flasks
Used for making very accurate
concentrations of solutions.
 Beakers/Flasks—accurate to about 5%
(50,000 ppm)
 Graduated cylinder—accurate to about 1%
(10,000 ppm)
 Volumetric Flasks—accurate about 0.04%
(400 ppm)
