UV Sterilization

Where Can UV Be Used?

UV radiation has shorter wavelengths compared to visible light and longer wavelengths compared to X-rays. UV radiation is divided into three Wavelengths: UV-A (315nm-400 nm), UV-B (280nm-315nm), UV-C (100nm-280nm) Different UV wavelengths and intensities are used for various purposes such as: Beneficial Germicidal Use: Used in industries that require water, air, and surface sterilization. Used in the food industry to provide safe and effective surface disinfection through UV irradiation. It helps preserve the nutritional value, reduce health hazards, and prolong the shelf life of food by sterilizing pathogens. Tanning and Skin Treatment: UVA beams are used to cause uniform tanning, which...

How effective is UVC Sterilization?

UV light is lethal to bacteria and viruses because of its high frequency of scrambles and damaging their nuclear material. When it damages the DNA (or RNA) code of these pathogens, it triggers lethal mutations that prevent them from reproducing correctly. When microorganisms are unable to multiply, it is considered dead since they cannot reproduce within a host and is no longer infectious.  UV light can kill a range of dangerous bacteria and viruses from MRSA to E.coli.UV light should never be used on the skin or any other part of the body. It would help if you were careful...

How long does it take for UVC to sterilize?

UV-C lights are utilized in various industries because of their germicidal effects. The UV-C light inactivates pathogens by destroying their nucleic acids and disrupting their DNA structure, rendering them unable to perform vital cellular functions, including reproduction. Hospitals have been using UV sources for a long time to disinfect surgical suits and reduce the spread of drug-resistant superbugs. UV-C is not available naturally on earth because it gets absorbed by the earth’s atmosphere and ozone. The human-made sources are used for Air and Surface applications. The effectiveness of sterilization depends on the total energy applied – dosage, which is affected...

Surface Disinfection by Exposure to UV light

UV-C light has a wavelength between 200nm to 280nm. The Cellular DNA and RNA heavily absorb this high energy short-wavelength germicidal light. Resulting in damages to their nucleic acids, which prevents the affected microorganism from infecting and reproduction, essentially killing and inactivating microorganisms such as bacteria, viruses, protozoa’s, and fungi.  Essentially, the absorbed UV-C energy results in the formation of new bonds between nucleotides creating thymine dimers. Excessive accumulation of thymine dimers in DNA prevent s the cell from doing its functions accurately and causes cell death. The distance between light source and surface is sufficient critical disinfection can be...
