256nm

256nm refers to a specific wavelength of ultraviolet (UV) light, measuring 256 nanometers. This falls within the UV-C spectrum, which is known for its germicidal properties. UV-C light at this wavelength is particularly effective at damaging the DNA and RNA of microorganisms, including bacteria, viruses, and mold, rendering them unable to reproduce and thus inactivating them.

This germicidal capability makes 256nm light a valuable tool in disinfection and sterilization applications. It is commonly used in water purification systems to kill harmful pathogens, in air purifiers to reduce airborne contaminants, and in medical and laboratory settings to sterilize equipment and surfaces. The effectiveness of UV-C at 256nm is due to its optimal absorption by nucleic acids, the building blocks of genetic material in living organisms.

While beneficial for disinfection, prolonged or direct exposure to UV-C light, including wavelengths around 256nm, can be harmful to human skin and eyes, potentially causing burns and long-term damage. Therefore, safety precautions are essential when working with UV-C sterilization equipment, typically involving shielding and limiting exposure times.
