Borosilicate Glass Rods and Discs
- Color: Clear
- Max. Temperature: 445° F
- Fabrication: Annealed
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
- Color: Clear
- Max. Temperature: See table
- Fabrication: See table
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 glass is stronger than annealed glass.
