hi there! a test tube is normally used to hold small amounts of material for lab testing or experiments.

To hold the test tubes orderly to easily identify them.
It is the wooden frame with holes in the top, most hold about 4-7 test tubes.
They are used to hold the tubes when you have to heat them with a reagent in them.

The test tube holder has many functions. It can be used to hold test tubes, making it easy to investigate the contents of the test tubes. These holders can also be used to hold stirring rods used in the laboratory and pipettes.
Test tubes are used to hold or store small amounts of chemicals or material dangerous to touch. If a scientist were to want to mix materials together, they would use a flask.
