Chemical properties of quartz sight glass is:

Quartz sight glass is good acid resistant materials, 30 times the chemical equivalent of acid resistant ceramic, equivalent to 150 times the Ni Cr alloy and ceramic, at high temperature and concentrated acid application superiority is obvious, in addition to 300 degrees above and outside, will not be eroded by other acids, especially under high temperature, sulfuric acid. Erosion and aqua regia.
