Sterilize Liquid Nitrogen for each situation

UV radiation is subdivided into UV-A (wavelength 315-400 nm), UV-B (280-315 nm), and UV-C (40-280 nm). UV-C is the most energetic portion of ultraviolet radiation; it can cause electronic excitation leading to the breaking of chemical bonds and the formation of unpaired electron species, known as radicals, that are highly reactive and can damage DNA and cell replication deactivating all kinds of microorganisms from viruses to fungi. The technology to generate UV-C is based on a bulb that contains gaseous mercury which, when subjected to electricity, emits an ultraviolet radiation, 95% of which is at 253.7 nanometers. This wavelength is in the region of maximum germicidal effectiveness and is highly lethal to virus, bacteria and mold spores.
