Bio•Wand Portable UV Sanitiser

The Bio•Wand™ available exclusively from Pro-Lab Diagnostics in the UK, uses UV light (265 to 280nm) to disinfect any object/surface in the lab and beyond. Bio•Wand™ can be set for a standard one-minute cleaning cycle or a more intense three-minute cycle. Simply press the power/start button and hold the light 1-2 inches from the surface and slowly move it over the entire target area. Allow the UV light to shine on the desired area for 5 to 10 seconds to ensure optimum exposure. The
Bio•Wand™ provides 2 hours of operating time and includes a USB-C cable for charging and portability.

“Coronaviruses (CoVs) are enveloped positive-sense RNA viruses and currently SARS-CoV-2 (Covid-19) is causing a global epidemic. Their exact survival time on different surfaces in the environment is currently unknown but it is thought to survive over 48 hours at average room temperature (20 °C). UVC light provides an alternative method of decontaminating surfaces during this epidemic period.UVC destroys viruses by high energy electrons passing through or diffusing through the protein coat into the nucleic acid core, resulting in damage of the viral RNA. The length of time taken to kill the microorganism depends upon exposure time and the range of the UVC emitter from the microorganism, in line with the inverse square law.”

It can be concluded that existing UVC disinfection systems and procedures will be sufficient to deal with all coronaviruses, including SARS-CoV-2, when used at 265-280nm.
