Good quality quartz glass material , high accurate , many sizes
Is a kind of high borosilicate glass, has excellent physical and chemical properties, its content of silicon in more than 80%, the internal structure of glass stability is extremely good, thus has good mechanical properties and chemical performance; Because of its low thermal expansion coefficient, can better withstand high temperature difference, and it has good light flame processing performance, is manufacturing laboratory various heating vessels, structure complicated glass apparatus, chemical equipment and pressure meter, such as glass, good glass materials.
