UV light is electromagnetic radiation with wavelengths shorter than visible light. UV can be separated into various wavelength ranges, with the short-wavelength UV, or UV-C considered to be germicidal. Furthermore, and at the specific wavelength range of 260 to 270 nm, UV-C is found to be mutagenic to bacteria, viruses and other microorganisms. Germicidal UV-C kills or inactivates microorganisms by destroying their nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. The SteriZAP™ UV-C Room Sterilizer harnesses the germicidal power of UV-C light, in particular in the 254 nm wavelength. This unit uses shortwave UV lamps that emit ultraviolet light with the major peak output (~90%) band at 253.7 nm. The doped fused quartz glass tubes of the SteriZAP™ lamps pass the 254 nm radiation (which produces very low ozone levels) but blocks the 185 nm wavelength (which produce higher ozone levels). The SteriZAP™ UV-C Room Sterilizer is intended for use in disinfection of surfaces in laboratories, hospital rooms, food-processing areas, or any other places where disinfecting and sterilizing are desired.
