Answer»

Answer:

Explanation:

It is THICKER and longer than a standard test tube, which it resembles, so that LIQUID doesn't BOIL over. The entire tube can be immersed in a BUNSEN burner flame because it is composed of borosilicate glass, a type of glass which is resistant to thermal shock and will not crack when exposed to extreme HEAT.
