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 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Because borosilicate glass doesn’t expand like ordinary glass, there is a smoother transition between temperatures as well as the ability to withstand different temperatures at the same time. Borosilicate glass has an extremely low coefficient of linear expansion (3.3 x 10 –6 K –1 ) as a result of its low thermal expansion.

Procedure: Wash the rubber plugs by agitation in a 0.2% v/v solution of Tween -80 or suitable anionic surface-active agent for 5 minutes at room temperature. Rinse 5 times with purified water. Weigh 20gm of rubber plugs, washed them and place in a 1000 ml borosilicate glass beaker, add 200 ml of purified water per 20gm of the closures and weight.

Borosilicate - A type of glass with main glass-forming constituents silica and boron oxide. Well know for having very low coefficient of thermal expansion (~5 × 10 -6 /°C at 20°C). However, there are many different borosilicate glasses made with various expansion coefficients (e.g. Pyrex and Borofloat are 32.5 while 7059 is 49).
The coefficient of thermal expansion of borosilicate glass over the temperature 0 - 300°C is 3.3 x 10-6/°C. This is very low when compared with other glasses and metals. That is why, borosilicate glass is often called low expansion borosilicate glass. Specific heat Specific heat between 25°C and 300°C is average to be 0.233Kcal/Kg, °C
