High-Purity Quartz Glass Tubes
We engineer our High-Purity Quartz Glass Tubes for superior performance in mission-critical thermal, chemical, and optical applications. Also known as Quartz Glass tubing, these tubes deliver exceptional thermal shock resistance, high purity, and excellent optical transmission. We manufacture them from select-grade Quartz Glass, thus making them the industry standard for semiconductor process tubes, furnace tubes, and UV lamp bodies where performance cannot be compromised.
Our quartz glass tubes are distinguished by their superior dimensional control and material integrity. For example, key advantages include ultra-high purity (≥ 99.99%) to prevent process contamination and outstanding performance at continuous high temperatures. In addition, we offer comprehensive custom fabrication, including cutting, grinding, and flanging to meet your exact specifications.
Material Integrity and Fabrication Excellence
The superior performance of our Quartz Glass Tubes begins with the manufacturing process. Indeed, we produce tubing with excellent concentricity and uniform wall thickness, which is critical for even heating and pressure resistance. As a result, this structural integrity ensures our tubes resist deformation and failure under demanding thermal and mechanical stress. Furthermore, the inherent high purity of the Quartz Glass prevents outgassing or leaching of contaminants into the process environment. This makes our tubes ideal for creating the ultra-clean conditions required in semiconductor and laboratory applications.

Key Applications for Quartz Glass Tubes
Our large-diameter Quartz Glass Tubes are essential for creating the process chamber in horizontal and vertical furnaces. In this context, their purity and ability to withstand high temperatures are critical for diffusion, oxidation, and LPCVD processes.
We supply UV-grade Quartz Glass Tubes with excellent transmission at germicidal wavelengths (185-254 nm). This, in turn, makes them the ideal material for high-performance UV disinfection lamps, water purification systems, and curing applications.
The exceptional thermal shock resistance of our quartz glass tubes makes them perfect for use as protection tubes for thermocouples, sight tubes, and liners in high-temperature industrial furnaces used for metal and glass processing.
