the use of test tube is when you have an experiment it is very use ful because you can use it as an xperiment or chemical containers!
Usually heat insulation plate is used
When selecting a material for an insulation factor it has to be balanced between flexibility and its insulation properties. Glass would be an excellent insulator but in the electrical field hard to pull through conduit and bending without damaging the insulation. Cross-linked polyethylene fits both the conditions for a wire insulation. The insulation has a high insulation factor plus the ability to bend without damaging the insulation and can operate in a 90 degree C temperature range.
It's not safe for residential use because it is quite flammable. Construction grade styrofoam insulation is treated with a flame retardant.
Insulation generally is required to meet standards for flammability. Plastic bags are not treated in any ay to prevent their combustion so it ould be like packing your walls with bottles of gasoline for insulation.
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.
The function of a boiling tube is to contain substances that are being heated in the flame of a Bunsen burner. They are small, cylindrical vessels made from borosilicate glass.a boiling tube is used for containing or heating small amounts of substances
It's a cylindrical vessel used to heat substances over a Bunsen burner.
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.

The student raised the test tube above the stand clamp with crucible tongs.
for insulation
Whales use fat or lipid molecules for energy and insulation.
equipment use for boiling
Insulation.
Can lights that are rated as IC "insulation contact" are the only style approved for use with blown or batt insulation.
styrofoam cups (coffee cups) are good insulation
