General UV-C Germicidal Information
UV-C germicidal technology utilizes ultraviolet (UV) light in the short wavelength range
between 200 to 280 nanometers to destroy the genetic material of these pathogens,
rendering them unable to replicate and cause infections.
Key Characteristics of UV-C Germicidal Light:
1. Wavelength: UV-C light has a wavelength of 200 to 280 nanometers, falling within
the germicidal range. This range is highly effective in disrupting the DNA and RNA of
microorganisms, preventing their growth and reproduction.
2. Germicidal Effectiveness: UV-C light is known for its high germicidal
effectiveness. It can inactivate a wide range of microorganisms, including bacteria,
viruses, fungi, and mold spores. It has been successfully used to combat pathogens such
as E. coli, influenza, norovirus, MRSA, and more.
3. Disinfection Mechanism: When microorganisms are exposed to UV-C light, the
energy from the light disrupts their genetic material, specifically damaging their DNA or
RNA. This prevents them from replicating and renders them harmless.
4. Dosage and Exposure Time: The effectiveness of UV-C germicidal light is
influenced by the dosage and exposure time. Higher dosages and longer exposure times
generally result in higher germicidal efficacy. The required dosage varies depending on
the specific microorganism being targeted.
5. Application Areas: UV-C germicidal technology finds applications in various
industries, including healthcare, food processing, water treatment, HVAC systems, and
laboratories. It is used for surface disinfection, air purification, and water sterilization
purposes.
6. Safety Considerations: UV-C light is harmful to human skin and eyes. Direct
exposure to UV-C light can cause burns and eye damage. Therefore, it is crucial to follow
safety guidelines and use appropriate protective measures, such as wearing protective
eyewear and ensuring that humans are not present in the vicinity during UV-C
disinfection cycles.
