Product Description
Borosilicate Glass entirely conforms to the international standard ISO3583, and is a new special borosilicate glass of excellent chemical and physical properties with a silica content of 80%. It is highly stable in structure and, as a result, has marked mechanical strength and very high resistance against chemical attacks. Further, due to its low linear coefficient of thermal expansion, this glass is capable of withstanding high thermal shock and possesses good moulding ability. It is an excellent material for making laboratory apparatus where external heating is necessary, intricate laboratory glassware and chemical equipments as well as pressure water meter glass.
