JGS-2 (UV optical quartz glass). It is an optical quartz glass made by oxyhydrogen flame melting and is suggested for applications in the wavelength range of 220-2500 nm !
Ozone free quartz. It is clear quartz tube doped with Ti. Has a strong ability to prevent dense UV radiation but release no ozone. Ozone-free quartz tubing is clear, with cut surface slight purple. The product blocks wavelength < 220 nm, while transmit over 70% in 253.7 nm. Good for all kinds of germcidal lamps.
UV stop quartz tubes. It is the best materials to prevent UV with best transparent performance. This cerium-added quartz tube can effectively prevent all radiation of UV-B and UV-C ultraviolet and most radiation of UV-A ultraviolet. It can be used to make quartz halogen lamp , gas discharge lamp and other UV lamp-house, which will effectively protect human and object from hurt of ultraviolet and maintain the best efficiency of light transmission.
