UV light is one of the proven ways to destroy DNA and RNA characteristic of all life forms. While we wait for a vaccine, Air Science experience in UV technology offers additional opportunities for clinicians and researchers to mitigate contamination.
Air Science has used UV in forensic science applications of many years. We have developed high-efficiency products that rapidly decontaminate DNA using high intensity UVC radiation. This is essential to protecting the chain of custody in evidence processing where DNA is processed from one case to another.
Our products are designed to safely decontaminate contents while providing a safe work environment for the operator.
Ultraviolet light is proven to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. In light of the current Coronavirus outbreak, UV germicidal lamps are being used to aid in disinfection of air, surfaces and equipment within hospitals and healthcare facilities, to help reduce and control the spread of the virus.
Scientists identified as early as 1989 that treating technology surfaces with doses of UV light could break down DNA and help minimize cross-contamination in sensitive polymerase chain reaction experiments. An article in the journal Nature claimed that UV irradiation was a way to “quickly damage any DNA left on exposed surfaces.”
Air Science UV-Box Applications
The Air Science UV-Box™ is a desktop unit that provides easy, effective UV radiation decontamination of personal protective equipment (PPE) such as N95 respirator masks, instruments, tools and materials. High intensity UV lamps positioned within the cabinet produce short wave ultraviolet light at 254 nm to destroy exposed surface bacteria and viruses, leaving medical equipment free of contamination.
UV-Box Features and Benefits
- UV lamps are optimally placed to eliminate blind spots and corners and walls are smooth to ensure easy cleaning. Stainless steel surfaces naturally reflect UV radiation to ensure contents are fully irradiated from all directions.
- Professional design and construction features offer convenience and protect the safety of personnel during use, cleaning and maintenance of the cabinets.
- The operator is protected from UV radiation by the UV absorbing window and with safety controls to ensure that lamps cannot be activated until the cabinet door is securely closed.
- Other safety features include UV timer, hanging rod and shelf to support or suspend items for decontamination.
