Product Description

large diameter clear tempered borosilicate glass tube with 5mm wall thickness

Borosilicate glass has a very low thermal expansion coefficient, about one-third that of ordinary glass. This reduces material stresses caused by temperature gradients, thus making it more resistant to breaking. This makes it a popular material for objects like telescope mirrors, where it is essential to have very little deviation in shape. It is also used in the processing of high-level material, where the waste is immobilised in the glass through a process known as vitrification .
