Support stands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.

17
Q

Test tube clamps

A

Utility clamps are used to secure test tubes, distillation columns, and burets to the support/retort stand.

18
Q

Iron ring clamps

Wire gauze sits on the iron ring to provide a place to stand a beaker.

20
Q

Test tube brushes/cleaners

A

Test tube brushes are used to clean test tubes and graduated cylinders.

21
Q

Glass stir rod

A

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

22
Q

Medicine (eye) dropper

A

A medicine dropper is used to transfer a small volume of liquid (less than one mL).On top of each medicine dropper is a “rubber bulb”

23
Q

Pipette

A

A pipette is another option to transfer a small volume of liquid—they come in multiple sizes

24
Q

Funnel

A

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

25
Q

Gas collecting bottle

A

We use gas collecting bottles when large volumes of gases are produced, and must be collected by the displacement of water.

26
Q

Watch Glass

A

A watch glass is used to hold a small amount of solid, such as the product of a reaction.

27
Q

Evaporating Dish
