Low Ozone Quartz Tube:
Colorless on surface, cut ends appear as light purple color. This product able to stop the ultraviolet radiation before 220nm, and 253.7 nm ultraviolet radiation wavelength through rate as obove 70%. This wave length ultraviolet radiation has strongest disinfectant, we name as sterilize or ozone free quartz tubing. Widely apply to sterilization, water treatment etc.
