The Eniware Portable Sterilizer

Our Eniware Portable Sterilizer (EPS-V2.0) is designed to be lightweight, durable, easy-to-use, safe, and effective for multiple uses. The EPS-V2.0 uses novel nitrogen dioxide (NO₂) technology to sterilize medical instruments at room temperature and without external power or water. The unit requires no external energy sources, including electricity or fuel, for operation. The system consists of a disposable, single-use Gas Generation Module (GGM) that generates nitrogen dioxide gas (NO₂) and a disposable, single-use scrubber that safely absorbs the gas after sterilization is complete. Medical instruments are placed inside the Sterilization Chamber, along with chemical indicators, allowing sterility to be maintained even after the unit has been opened. 

How It Works: 

  1. User loads surgical instrument trays into the sterilization chamber and powers on the system.

  2. User inserts Gas Generation Module (GGM) and Scrubber/Humidity Cartridge.

  3. User closes the sterilization chamber and latches the chamber lid. The sterilization cycle begins and NO2 Gas is generated by the GGM. Note: Gas is NOT generated before the sterilization cycle begins.

  4. At the end of the sterilization cycle, residual NO2 gas is completely scrubbed from the unit.

  5. The surgical instruments are now sterile and safe to be used immediately with no down time. (Surgical instruments can also be left inside of the sterilization chamber for up to 2 weeks where sterility will be maintained until the chamber is opened.)
