Objective
To evaluate the efficacy and the dose response of NuvaWave Instant UV handheld device in reducing Escherichia coli (E. coli) on surfaces
Methodology
Utilizing ASTM E3135 standard practice to evaluate the ultraviolet germicidal irradiation designed to kill/inactivate microorganisms deposited on inanimate carriers, such as steel or glass. The carriers were inserted into a computer controlled robotic NuvaWave test device (112 mW/cm2 ) irradiated the pathogen carriers at a separation distance of 2 inches for a defined period of time. The dose and time for each period was recorded. The irradiated pathogens were compared to a non-irradiated control group to determine the amount of inactivation.
Summary of Results
The NuvaWave handheld device deactivated 99.99% of Escherichia coli (E. coli) after one second of exposure.
