High-Purity Quartz Glass Tubing: Exceptional Heat Resistance and Versatility

Our high-purity quartz glass tubing, crafted from pure silica, offers exceptional purity, clarity, and remarkable heat resistance up to 1200°C. We provide a wide range of sizes, with outside diameters ranging from 2mm to 800mm and rods available from 2mm to 45mm. In addition to standard forms, our advanced processing capabilities allow us to customise tubes into various shapes and configurations.

Quartz glass tubes possess numerous properties that make them invaluable in diverse industrial applications. They are commonly used in the preparation of envelopes for high-temperature light sources, including xenon, ultraviolet, and halogen lamps. The exceptional heat resistance of quartz glass, reaching up to 1200°C, far surpasses that of borosilicate (300°C), making it an ideal choice for demanding environments.

Quartz rods are available in diameters from 2mm to 80mm. In the semiconductor industry and power applications, these rods are widely valued for their excellent high-voltage insulation properties.
