This material is commonly called 'germicidal' or 'ozone free' quartz glass. It is produced to transmit UV-A and UV-B while blocking the deep high wavelengths. This makes it the ideal material for many disinfecting applications and various other UV treatment applications.

Our clear quartz tubing features high purity (>99.99%), good physical and chemical properties, tight tolerances, and low -OH content. The tubes are used in a variety of applications by our customers. Special dimensions and tolerances are available upon requests. We also offer UV-cutoff tubing, ozone free tubing and irregular-shaped tubing.
Transparent Quartz tubes widely apply to Semiconductor, Lighting, and Electric heating Industrial field.
