Materials | Borosilicate | SCHOTT Duran® 8330 Glass

Glass Type: Borosilicate

Description

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