Temperature Resistance:

Thermal resistance is a good gauge to how well the glass handles high heat and yet retains its shape and structural integrity. Factors that should be specially considered are softening temperature and coefficient of heat. Our borosilicate glass has high softening temperatures and low coefficient of heat enabling our glassware to withstand heat and also have a higher range of working temperatures. Special care must still be taken at temperatures above 140^oC to heating and cooling to be done in a most uniform manner.

Chemical Resistance:

Borosilicate glass has a very high resistance to attack from water, acids, salt solutions, halogens and organic solvents. Only concentrated phosphoric acid and strong alkaline solution cause significant corrosion of the glass.
