Product Details

01-Product Preview:

 

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 glass 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 SimaxBorcamBorosil, Suprax, KimaxHeatexPyrexEnduralSchott, orRefmex.
