What is Nitrogen Dioxide Sterilization?
No aeration required
Room Temperature Sterilization
Safe for most heat and moisture sensitive materials
Safe for most medical materials
The Eniware Portable Sterilizer (EPS-25) uses novel nitrogen dioxide (NO₂) technology to sterilize instruments at room temperature and without external power or water. Nitrogen dioxide is a reddish-brown gas that is generated through a chemical reaction when the SterilNox Ampoule is placed and engaged in the EPS-25. While it is commonly found as a byproduct of factories, cars, and power plants, NO₂ gas has also been proven to be an effective and safe chemical sterilant. Nitrogen dioxide has been shown to be effective against a wide range of microorganisms, including bacteria, viruses, and spores, and it works as a sterilant by degrading the microorganism’s DNA through single-strand breaks. NO₂ gas is a small molecule with a low boiling point, making it especially good at diffusing into complex devices and filling spaces. While NO₂ can be toxic at very high concentrations, it is dramatically safer than similar sterilant gases such as hydrogen peroxide, ethylene oxide, or chlorine dioxide and requires a smaller concentration to be effective. Unlike autoclaves, which require large amounts of electricity and distilled water, NO₂ sterilization within the EPS-25 does not require external power or water, and because it works at ambient temperature and pressure, it is uniquely suited for low-resource settings.
