Soda Lime Glass

Soda Lime Glass is resistant to high- alkaline solutions. Soda lime glass balls are mainly used in applications which are not subject to strong mechanical or thermal shocks such as plastic bearings, flow meters, measurement and control equipment, ink cartridges.

Borosilicate Glass

Borosilicate Glass has an excellent chemical inertia to most acids and thus it is particularly suitable for metering pumps and valves against strong oxidant concentrations.

Black Glass

This is often used in medical and chemical flow meters and for control and measurement equipment.
