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

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.
