It's a cylindrical vessel used to heat substances over a Bunsen burner.
A sample tube, culture tube, sometimes a boiling tube.
A boiling tube is for boiling chemicals or metals, a test-tube is for holding chemical reactants. Test tubes are slimmer, boiling tubes are wide and are made of thin glass

Provided that you use the wider kind of tube known as a boiling tube, this is not so. Of course it is dangerous to heat liquids in a narrow tube, as this can cause rapid boiling and the shooting of the liquid out of the tube.

A retort stand is to hold a test tube/ boiling tube. 1. Turn the side knob( by the "t" on the retort stand) and release it. 2. Put the test tube/boiling tube in the test tube/boiling tube holder. 3. TIGHTEN the side knob ( if not the test tube/ boiling tube will drop). 4. Adjust the height of the retort stand by turining the most corner knob. (if you need to)
Boiling tubes are used to heat substances to extreme temperatures. Boiling tubes are almost twice the size of regular test tubes. They are designed to allow substances to violently boil without boiling over or exploding out.
