BILLES VERRE

Thanks to their chemical strength, their electric insulation and transparent properties, glass balls are used in various scientific applications, in chemistry, in engineering and in other industries.


Raw materials

Standard diameters

Glass balls diameters usually go from 1 mm to 20 mm but production can be done up to diameter 100 mm in a special glass. Please find below standard diameters that can be found from stock.

Tolerances

Glass balls can be produced from different standards. The most common standards are the following

– DIN 5401 standard (the German standardization system)
– ANSI/ABMA standard (the American standardization system)
– ISO 3290 standard (the European standardization system)

No matter what standard is used, the essential control points are the same because all standards have equivalences.
