This device maintains sterilization through irradiation with short wave ultraviolet rays . The vapor of mercury at low pressure contained in the lamp, submitted to electric discharge, give out a short wave radiations that will be distribute for the 90% around the frequency of 253,7 nm, and in tall frequencies the lamp give out a visible light of bluish color. It is just around the 253,7 nm that is developed the maximum germicidal power.

 

The ultraviolet radiations are lethal for the microorganisms. The quantity of radiation necessary to destroy a microorganism depends from the type of the microorganism and from the environmental conditions. The lethal dose of radiation UV for a determined microorganism depends therefore from the intensity of the source, from the exposure time and from other factors like temperature, damp and the reflection formalities of the rays. Our apparatus has been planned and built in way to maximize the effect of the radiations and to assure an optimal result in varied uses. It is ideal for a suitable maintenance of the tools after the sterilization.
