Borosilicate glass
Borosilicate glass is a type of
glass with
silica and
boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low
coefficients of thermal expansion (~3 × 10
-6 /°C at 20 °C), making them resistant to
thermal shock, more so than any other common glass. Such glasmades is less subject to
thermal stress and is commonly used for the construction of
reagent bottles. Borosilicate glass is sold under such trade names as
Simax,
Borcam,
Borosil, Suprax,
Kimax, Heatex,
Pyrex,
Endural,
Schott, or
Refmex,
Kimble.
