ballcenter Our glass balls – precision meets chemical stability

Glass balls are used for technical appli­cations that call for high chemical stability. One of the benefits of glass balls is that they demon­strate perma­nent stability for all pH solu­tions, from alkaline to acidic.

Common appli­cations for glass balls are valves for metering pumps in the chemical industry, roller conveyor tech­nology for the photo­graphy industry, and sprays and dispen­sers for cos­metics and pharma­ceuticals.

Glaskugeln Borosilicate glass balls – extremely resistant

Borosilicate glass balls – known as boro – have superior resistance to aggressive chemicals, high temperatures or sudden temperature fluctuations. For that reason, you will often see them used in special applications such as in the cosmetics industry or medical sector.

Properties:

  • Material: Borosilicate glass – CAS no. 65997-17-3 / EC no. 266-046-0
  • Diameter: 1 mm to 100 mm
  • Grade: G100, comparable to steel balls
  • Surface mat/frosted Ra: 0.60µm
  • Surface clear/polished Ra: <0,1µm
