We product the glass instruments is based on the different technical requirements for products and production processes, not properties of glass were used to create, first I plant mainly physical and chemical properties of several glass summarized as follows:

GG-17 High Temperature Glass full compliance with ISO3583 international standard, is a high-borosilicate glass, has excellent physical and chemical properties, its silicon content above 80%, the stability of the internal structure of the glass very well, and hence have a good mechanical and chemical properties, due to its low thermal expansion coefficient, better tolerance to high temperature, and has good processing properties lamp flame, is to create a variety of laboratory heating vessel, the structure of complex glass apparatus, chemical equipment and pressure meter glass of good glass.
