Materials | Borosilicate | SCHOTT Duran(R) 8330 Glass

Glass Type: Borosilicate

Description

SCHOTT Duran(R) 8330 glass is a chemically and thermally highly resistant borosilicate glass available in tubes, capillaries, and rods. SCHOTT Duran(R) 8330 glass comes standard in many sizes and is frequently used in place of Corning(R) Pyrex(R) 7740 material. CGQPI can cut, shapes, centerless grind, and hot work Duran(R) material in many sizes and shapes.
