Zadro Nano disinfection scanners help prevent spread of colds and flu by seeing the bacteria and killing it. The Zadro Nano Scanner emits ultra-violet light that disinfects surfaces and kills 99.9% of germs with no toxins or side effects. Ocelco carried Zandro Nano’s large Wand scanner as well, which disinfects a larger area at a time. The No Rinse Foaming Hand Sanitizer is alcohol free with aloe vera. No Rinse foaming hand sanitizer is perfect when water and soap is not available.
