Borosilicate Glass Rods and Discs

Also called Pyrex and Schott glass, this glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.

Also Available: Other disc sizes. Please select 8477K98 and specify the diameter and length.

Pressure-Rated Borosilicate Glass Discs

Commonly used as sight glass. Also called Pyrex and Schott glass, borosilicate glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature.

Tempered—Tempered glass is stronger than annealed glass.
