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.

To measure the depth of a test tube, you can use a ruler or caliper. A ruler can be placed alongside the test tube to read the depth directly, while a caliper can provide a more precise measurement by fitting snugly inside the tube. If the test tube is transparent, you could also use a water level to gauge the depth by marking the water level as it is filled.
