Scoopula
Used for measuring small amounts of chemicals.
Never stick these directly into a bottle of chemicals. You can contaminate the entire bottle.
C. GogglesD. Hose Clamp
Used for eye protection. You will lose points in lab if you don’t.
Hose Clamp (not pictured)
E. Wash bottleF. Rubber Stoppers
Use this for “rinsing” chemicals into your reaction vessel.
Not squirting your classmates.
Rubber stoppers (not pictured) are for closing up test tubes.
G. Disposable PipetH. Test Tube Clamp
Disposable Pipet (not pictured) used as a dropper for measuring out liquids.
Test Tube Clamp or Test Tube Holder
I. Test TubesL. Test Tube Rack
Test Tubes are a medium sized reaction vessel, where you are
using 1-5 mL or less.
J. Graduated CylinderUse these to accurately
measure liquids in lab.
Never use beakers or flasks to measure.
The answer on the SOL is always GRADUATED CYLINDER.

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 = 0.05 mL.
So, 20 drops = 1 mL.
K. Combustion SpoonM. Thermometer
We use Celcius (°C) and Kelvin (K) temperature in Chemistry.
K = °C + 273
Combustion spoon (not pictured).
P. Watchglass
2 uses:
Use as a “plate” to hold solid samples during experiments.
Use as a “lid” to cover a beaker.
Q. Funnel
Used with filter paper.
Use for filtration (which is a physical separation technique)
Separates a solid from a liquid.
T. Clay Triangle
Used to safely heat crucibles.
Use with a ring stand and ring clamp (next slide).
Heat crucible using a bunsen burner.
U. Ring Clamp
Used as a “platform” for heating things SAFELY.
Use with a Clay Triangle to heat crucibles.
V. Wire Gauze
Use this on top of a Ring Clamp for heating beakers or flasks or
even evaporating dishes.
W. Erlenmeyer Flask
Erlenmeyer is a person’s name and should be capitalized.
Used as a large reaction “vessel” in lab. You can swirl!
X. Ring StandZ. Utility Clamp
Ring stand is used for building things. Use with ring clamp
or other clamps.Utility clamp is at the
bottom (it is fuzzy)
Y. Bunsen Burner
Bunsen is a person’s name and should be capitalized.
Used for safely heating things in lab. Flame is 1500°C (2700°F)

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
(or any glass) directly in
the flame while heating.
4. Never point a test tube
at someone else while
heating.
$. Volumetric Pipet
Used for accurately transferring a precisely measured amount of liquid.
Never use your mouth to suck liquid into the pipet. Use the rubber bulb.

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)
Glass Stirring RodNot on Handout
Used for (duh) stirring stuff.
Glass is inert (means doesn’t react).
But they do break. Breaking glass is number 1 accident in lab.
Mortar & PestleNot on Handout
Mortar = bowl and Pestle = stick.
Used for grinding up solids or mixing solids thoroughly.
Pharmacists use these a lot when making customized medicines.
