Clark Borosilicate Glass Rod

Product Summary

The properties of borosilicate glass make it the most popular material among researchers for the fabrication of probes and special holders.

  • High quality borosilicate glass

Its low softening temperature combined with its mechanical strength, chemical resistance, high electrical resistivity, and its ability to withstand thermal stress make these glass rods the most widely used in the world.

The end user can manufacture their own probes and special holders using standard pipette pulling and microforge techniques

Composition 80.9% SiO2, 12.9% B2O3,
4.4% Na2O, 1.8% Al2O3
Softening Temp 815°C
Dielectric Const 4.7
