Beaker

• A beaker is a type of glassware which consists of a cup with a pouring lip on top. They are about as wide as they are tall. This makes beakers very stable and easy to handle. Beakers allow an easy rough measure of liquid volume.

• Beakers are used to heat solutions using a Bunsen burner or a hot plate.

Beaker Tongs
