UltraBLU is lab tested and Verified by Situ Biosciences & EMSL AnalyticalUltraBLU™ is a UV-C LED source designed for sterilization and disinfection applications. UV-C refers to class of ultraviolet energy wavelengths that have a unique ability to kill viruses, specifically in this lab study, SARS CoV-19, bacteria, molds and other pathogens. With recent innovations in LED technologies, LED emitters are now powerful enough to be used for UVGI (ultraviolet germicidal irradiation) applications.
