NST Desktop UV Ozone Cleaner

NST DESKTOP UV OZONE CLEANER has proven to be highly effective for non-acidic, dry, non-destructive atomic cleaning and removal of organic contaminants using intense 185 nm and 254 nm UV light. Under air and room temperature, the 185 line produces Ozone and while the 254 line excites organic molecules on the surface. This combination drives the rapid destruction and decimation of organic contaminants.
