A test tube is usually used to contain small amounts of fluids, usually to react or to hold temporarily. It is also used to clearly observe different reacting samples of chemicals in a experiment which usually call for many test tubes. Heating a test tube is done by a water bath, but usually not direct heat. Also, an inverted test tube can be used for gas collection in a gas emitting reaction by water displacement.
