Ozone-free Quartz Tubes: A kind of transparent quartz glass tube with titanium additive for strong ultraviolet radiation prevention, producing no ozone. Applicable for ozone-free ultraviolet germicidal lamps and other luminous source lamps.
Standard Transparent Quartz Tubes: Standard transparent quartz glass tubes made from high-purity quartz grain by means of automatic continuous melting equipment. They are featured excellent properties such as high purity, great thermal stability, high transmissivity, great acid endurance and precise measurement. These tubes have been processed with normal or vacuum dehydroxylation. Stable products with hydroxyl content of 1--20ppm are available. The products are widely used in high-technology fields such as semiconductor, IC manufacturing, optical fiber communication, laser technology, spaceflight technology, national defence, military project and optics industry.
UV filter quartz tube: Such cerium-doped silica glass tubes can effectively prevent all the UVB and UVC radiations and large portion of UVA radiation. As an ideal material for lamps with all-round UV-stop function and maximum transmissivity, they can be applied to quartz halogen lamps, gas discharge lamps and other UV luminous sources. While bearing the excellent basic physical and chemical properties found in ordinary quartz glass tubes, they can also efficiently screen out the 190¡ª320 nm ultraviolet rays in UV spectrum and eventually prevent their harm to human body and objects. These tubes can be used for various environment-friendly electric light sources due to their capacity of maintaining the maximum propagation rate of visible light.
