6 Types of Tubes Used in Science Laboratories - Machined Quartz
Apr 1, 2021 · Boiling Tube “It’s a thick cylindrical used for boiling chemicals. The boiling tube is thicker and about 50% bigger in size compared to a standard tube. It is composed of borosilicate glass which is strong against thermal shocks. This tube material wouldn’t break or melt even when exposed to extreme heat.
