Glass Composition

WPI's line of GG17 laboratory glassware conforms to the international standard ISO 3583. This is a special Borosilicate 3.3 Glass of excellent chemical and physical propertees with a silica content of 80%. It is highly stable in structure, and as a result, it has marked mechanical strength and very high resistance against chemical attacks. Further, due to its linear coefficient of thermal expansion, this glass is capable of withstanding high thermal shock and possesses good molding ability. It is an excellent material for making laboratory apparatus where external heating is necessary, intricate laboratory glassware and chemical equipment, as well as pressure water meter glass.
