Quartz UVC germicidal tube, its emission spectral line 253.7nm wavelength is invisible to the naked eye. The wavelength of 253.7nm can play a good bactericidal effect. This is because cells have a law in the absorption spectrum of light waves, and they have a large absorption of ultraviolet rays with a wavelength of 250nm~270nm. The absorbed ultraviolet rays actually act on the genetic material of cells. That is, DNA, which causes genetic material to mutate, causing bacteria to die immediately or unable to reproduce offspring to achieve the purpose of sterilization. UVC tube is widely used in hospital disinfection, food hygiene, equipment disinfection, different hygiene places and leather aging.
