Company launches new UltraV™ 1000 UVC Dosimeter to support UV-C disinfection of respirators
Apr 13, 2020 — STOCKHOLM — In the global fight against COVID-19, health care facilities and providers around the world are faced with critical shortages of disposable filtering facepiece respirators (FFRs), often referred to as N95 masks. Fortunately, innovative manufacturers are utilizing their expertise to design systems that can decontaminate N95 masks with ultraviolet germicidal irradiation (UVGI) along with a new, color- changing visual indicator that shows if an optimal dose of UV-C irradiation has been delivered.
To support the critical capacity strategy of using of UVGI for N95 decontamination, Intellego Technologies has launched the UltraV™ 1000 UVC Dosimeter, a 1″ square indicator that changes color to visually indicate exposure levels of UV-C irradiation. According to a summary of research compiled by the Centers for Disease Control and Prevention¹, the use of UVGI at an accumulated dose of ~1,000 mJ /cm2 can deliver a 3-log (99.9%) reduction of viruses which have similar characteristics to SARS-CoV-2 that is responsible for the COVID-19 pandemic.
“When we learned of the capability of UVGI to decontaminate N95 masks, we immediately shifted gears to validate and produce this new dosimeter that provides visible indication of the desired 1,000 mJ/cm² dosage,” said Claes Lindahl, CEO of Intellego Technologies. “Along with our current UltraV™ 100 UVC Dosimeters that are primarily used with UV-C room disinfection systems to visually indicate dosage that correlates to a 3-log reduction of MRSA and C. Diff², we are proud to make available the new UltraV™ 1000 UVC Dosimeters to help mitigate shortages of N95 masks and fight the global COVID-19 pandemic.”
Intellego Technologies’ UltraV™ 1000 UVC Dosimeters are uniquely designed to work with UVGI systems that use low-pressure mercury vapor lamps to quickly irradiate objects such as N95 masks that are placed in close proximity to the UV-C light source. Because disinfection of surfaces is an invisible process, having a color-changing indicator that responds to the appropriate dose of UVGI is an important, visible tool to ensure that personal protective equipment like the N95 masks are sufficiently decontaminated for reuse.
UltraV™ 1000 UVC Dosimeters have been independently validated by RISE Research Institutes of Sweden AB. The dosimeters’ patented UV-sensitive material is matched to correlating Pantone colors to visually indicate a range of UV-C dosage levels of 250, 500, 750, and 1,000 mJ/cm2 . With this visual calibration, UltraV™ 1000 UVC Dosimeters can be used alongside N95 masks being treated with UVGI. UltraV™ 1000 UVC Dosimeters come with an easy-to-read Color Reference Chart so technicians can visually identify that an accumulated dose of ~1,000 mJ/cm² of UV-C irradiation has been reached.
UltraV™ 1000 UVC Dosimeters will be utilized by leading UV manufacturers around the world and are available to health care facilities and researchers who are working to mitigate the critical shortage of disposable FFRs.
