Ultraviolet rays with a wavelength of 185nm react with O2 in the air, changing O2 into O3, and the high O3 content will cause great harm to human body. When mixed with Ti(titaniumoxide) of 100-200PPM in the quartz glass, has the function of absorbing and intercepting the ultraviolet ray with the wavelength below 220nm, preventing O2 react with 185mn wavelength ultraviolet, yet wavelength 253.7nm penetration rate can reach 83% (the wavelength with the best sterilization effect is 253.7nm).This is how ozone-free quartz tube works. Therefore, ozone-free quartz tube is an ideal material for ultraviolet bactericidal lamps in homes, hospitals and public places and other safe& green products.
