CUV Series ultraviolet sterilizer, also known as UV sterilizer, is a device that uses ultraviolet (UV) light to kill or deactivate microorganisms such as bacteria, viruses, and fungi. The UV radiation damages the DNA or RNA of these microorganisms, preventing them from reproducing and effectively killing them.

UV sterilizers are commonly used in various settings, including water treatment plants, hospitals, laboratories, and food processing facilities, to disinfect water, air, and surfaces. They can also be used in aquariums and fish tanks to kill harmful bacteria and algae.

UV sterilizers typically consist of a chamber or tube containing one or more UV lamps, which emit UV-C radiation, the most germicidal type of UV light. The lamps are often surrounded by a quartz sleeve to protect them from the water or air being sterilized.

The effectiveness of a UV sterilizer depends on various factors, including the intensity of the UV-C radiation, the duration of exposure, the distance between the lamp and the target microorganisms, and the quality of the quartz sleeve. It's important to note that UV sterilizers are not effective against all types of microorganisms, such as spores, and should be used in conjunction with other disinfection methods for optimal results.
