Borosilicate glass from GVB
We have the right material for your application
You need components made of Borosilicate glass 3.3?
GVB offers you a wide range of cylindrical and flat borosilicate glasses. In addition, we also supply components such as standard ground joints and threads in a wide variety of designs.
Our borosilicate glass 3.3 is food safe, extremely sturdy, impact and scratch resistant. It is characterised by extraordinary temperature resistance and can withstand even strong temperature changes.
Compared to quartz glass, our borosilicate glass plates are much easier to work with, making them ideal for flexible further processing.
Our Boroplates are made of high-quality borosilicate glass 3.3 and are manufactured using the float process. This results in exceptionally flat, low-stress glass plates with uniform thickness and excellent surface quality.
