Chemistry Lab

Equipment

A. Well Plate

Used as a “small scale” reaction vessel, where you are only using drops of

solutions.

B. Scoopula

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).

Back Side of HandoutN. Tongs

Used for picking up hot pieces of equipment

O. Crucible and Lid

Used for STRONG Heating

Use tongs to pick up while

heating

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.

R. Beaker

Used ONLY as a “container” for liquids.

NEVER used for measuring. Lines are not accurate.

S. Evaporating Dish

Used for GENTLE

heating or NO heating

Use tongs while heating.

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)

Safe

ty

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.

Volumetric FlaskNot on Handout

Used for making very accurate solutions (mixtures).

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.
