Precision glass balls

An important point for the use of precision glass spheres is the application purpose. With this information we can fix the kind of glass and the necessary toleInsulinrance for the usage of the ball.
Precision glass balls are mainly used in industry, pharmacy, research, electronics, optics and lighting technology. For example, do our glass beads Ø 2,5 mm mix up the insulin inside the insulin cartridge or are installed in a valve seat.

Due to the favorable properties there is mainly borosilicate glass processed, which is characterized by a low sensitivity to temperature changes and dimensional stability up to about 550 C. In addition, borosilicate glass is chemically resistant and does not react catalytically. On request, we also offer other special glasses.

We provide you with precision balls from a diameter of 0.25 mm with a quality of grade 3.
