Lab Equipment and

Procedures!!!!

Erlenmeyer Flask

• The Erlenmeyer flask is the most

common flask in the chemistry lab. It is

used to contain reactions.

Florence Flask

The rounded bottom of the Florence flask

makes it ideal for boiling liquids. It also makes this flask easy to tip

over when sitting on the lab table.

BeakersBeakers are the most versatile

glassware in the lab and can be used for just about anything.

The volume graduations on

beakers should be used only for

"ballpark" estimates.

Graduated cylinder

Used to make accurate measurements of

liquid volumes. The bumper ring on larger cylinders is to prevent

breakage if tipped over. Keep it near the

top.

Evaporating DishThis evaporating

dish is used to recover dissolved

solids by evaporation. While it can be

heated, it should not be used for "strong"

heating.

Watch Glass

A watch glass can be used like an

evaporating dish for very small amounts of liquid. It can also be

used to cover beakers or evaporating dishes.

Ring Stand and Iron Ring

When attached to the ring stand, this iron ring is used to support glassware

above the lab table.

Crucibles

Crucibles are used as a

container when something

requires "strong" heating.

Tongs

These tongs are used for picking up

crucibles and crucible covers

only.

Mortar and Pestle

Used to grind solids into powers.

Test Tube Holder and Rack

The test tube holder is used when

heating a substance in the test tube

over an open flame.

The test tube rack is used for storing test tubes so that they do

not tip over.

Buret

A buret is used to measure volumes of

solutions during a titration.

Plastic Wash Bottle

A plastic wash bottle is used

to dispense water.

Funnel

A funnel is used for filtrations

where solids are separated from

liquids.

Goggles

Goggles are used to protect you eyes during

lab.

Scoopula and Forcep

A forcep is used to hold or pick upsmall objects.

A scoopula (or spatula) is used to

transfer solid chemicals.

Clay TriangleA clay triangle is used to support

a crucible.

Double Buret Clamp

The double buret clamp is used for

holding burets during a titration. They can also be used to hold

a eudiometer.

Bunsen Burner

The Bunsen burner is a gas burner

used forheating

substances.

Wire Gauze

Wire gauze is used to spread

the heat of a Bunsen

burner.

Stirring Rod

Big shock…these are used for

stirring…. But please do not use

them to crush things…

They are glass and they will break.

How to…• Light a Bunsen Burner

• Read a graduated cylinder

• Use a digital balance
