Ultra-High-Temperature Quartz Glass Rods and Discs

Able to withstand temperatures up to 2100° F, this quartz glass is useful in high-temperature applications that also require optical clarity, such as high-intensity lighting, fiber-optic production, and optical lens systems. It provides excellent UV transmission, as well as high transmission in the visible and infrared ranges.

Ultra-High-Temperature Quartz Glass Sheets

These sheets won't deform when exposed to temperatures up to 2100° F or from drastic temperature changes. Compared to borosilicate glass, they handle five times more heat. These sheets are highly pure and will not leach impurities into laboratory or electronics manufacturing processes. They're also optically clear and have excellent UV transmission, making them ideal for UV purification systems.

Ultra-High-Temperature Quartz Glass Tubes

Blistering temperatures won’t melt these quartz tubes, and rapid temperature shifts won’t cause them to crack. Even tougher than borosilicate, they can be used in furnaces and ovens heated up to 2000° F. These highly pure tubes are often used in laboratories because they won’t leach impurities into samples or contaminate chemical reactions. Quartz tubes are optically clear and have excellent UV transmission, making them ideal for UV purification systems.
