Test tubes are used to hold, mix, and heat chemical experiments. They are used as homes for microorganisms when people want to culture (grow) them. They are also used as collections devices for things like blood samples.

Correspondingly, how should test tubes be safely used?

Heating Safety

2) Point test tubes away from yourself and others when heating substances in them. 3) Use the proper procedures when lighting a Bunsen burner. 4) To avoid burns, do not handle heated glassware or materials directly. Use tongs, test-tube holders, or heat-resistant gloves or mitts.

Likewise, is a test tube good for measuring? A typical test tube has a rounded bottom, but NMR tubes and certain other test tubes have a flat bottom, so the volume contained in them is a cylinder. You can get a reasonably accurate measure of volume by measuring the internal diameter of the tube and the height of the liquid.
