Test tube holder

A test tube holder is useful for holding a test tube which is too hot to handle.

Page 7: Lab apparatus

Test tube racks

Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes.

Stirring Rod

A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution.

Page 11: Lab apparatus


A funnel is used to aid in the transfer of liquid from one vessel to another.

Page 12: Lab apparatus


A pipette or medicine dropper is used to transfer a small volume of liquid (less than one mL).

On top of each dropper is a “rubber bulb”

Clay Triangle

The clay triangle is used as a support for porcelein crucibles when being heated over a Bunsen burner.

Page 22: Lab apparatus

Evaporating Dish

The evaporating dish is used for the heating of stable solid compounds and elements.

Page 23: Lab apparatus


Crucibles are used for heating certain solids, particularly metals, to very high temperatures.

Page 24: Lab apparatus

Crucible Tongs

For handling hot crucibles; also used to pick up other hot objects. NOT to be used for picking up beakers!
