Common Chemistry Lab Equipment
Chemistry Lab Drawer
Well PlateUsed for “small scale” reactions, where you are only using drops of
solutions.
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
Lab Apron (Folded)Goggles (top right)
Chemistry Lab Drawer
Wash bottle. Use this for “rinsing” chemicals into your
reaction vessel.
Chemistry Lab Drawer
Test Tube Rack and Test TubesTest Tubes are another “primary”
reaction vessel
Chemistry Lab DrawerGraduated Cylinder
Use these to accurately measure liquids in lab. Never use beakers to measure.
The answer on the SOL is always GRADUATED CYLINDER.
Volumes.We will work with liters (L) and
milliliters (mL) in this class. 1000 mL = 1L; 1000 L = 1 m3
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.

lab.Swirl
Chemistry Lab Drawer
Ring Stand and ClampsRing Clamps and Utility Clamps
Chemistry Lab Drawer
Wire Gauze with Ceramic CenterUse this for heating beakers or
flasks.
Chemistry Lab Drawer
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
Pipets and Pipet bulbNEVER use your mouth to
pipet.
Chemistry Lab DrawerNot on Handout
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)
