Common Chemistry Lab Equipment

Chemistry Lab Drawer

Well PlateUsed for “small scale” reactions, where you are only using drops of

solutions.

Chemistry Lab Drawer

Test Tube Rack and Test TubesTest Tubes are another “primary”

reaction vessel

Chemistry Lab Drawer

Test Tube Holder

Chemistry Lab Drawer

Erlenmeyer FlaskUsed as a reaction “vessel” in

lab.Swirl

Chemistry Lab Drawer

Beakers

Chemistry Lab DrawerMicro Spatula and

ScoopulaUsed for measuring

small amounts of chemicals.

Never stick these directly into a bottle of chemicals.

You can contaminate the entire bottle.

Chemistry Lab Drawer

Wash bottle. Use this for “rinsing” chemicals into your

reaction vessel.

Chemistry Lab DrawerGraduated Cylinder

Use these to accurately measure liquids in lab. Never use beakers to measure.

The answer on the SOL to is always GRADUATED CYLINDER.

Volumes.We will work with liters (L) and

milliliters (mL) in this class. 1000 mL = 1L.Cubic centimeters (cm3) and

milliliters (mL) are different names for the same amount. 1 mL = 1 cm3.

1 drop from a dropper is approximately 0.05 mL. So, 20 drops = 1 mL.

Bunsen Burner

Bunsen Burner Safety1. 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.

Chemistry Lab Drawer

Wire Gauze with Ceramic CenterUse this for heating beakers or

flasks.

Chemistry Lab Drawer

Striker

Chemistry Lab Drawer

Pipets and Pipet bulbNEVER use your mouth to

pipet.

PipetsUsed 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.

Chemistry Lab Drawer

Volumetric flasks

Volumetric FlasksUsed 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)

Chemistry Lab Drawer

Buret on ring standUsed for titrations.

Chemistry Lab Drawer

Stirring Rods

Chemistry Lab Drawer

Test tube brushes

Chemistry Lab Drawer

Red and Blue Litmus Paper

Chemistry Lab Drawer

Lab Apron (Folded)

Chemistry Lab Drawer

Mortar and Pestle. Used for grinding up solids or mixing

solids.
