Hospitals and specialty clinics need a safe, compatible and reliable process to sterilize medical instruments of every kind, including medical devices that would degrade if processed with steam or
hydrogen peroxide:

  • Plastic
  • Cellulose
  • Rubber
  • Sharps

Our state-of-the-art EOGas 4PLUS system, featuring Ethylene Oxide-Flexible Chamber Technology (EO-FCT), delivers. EO-FCT is significantly different than traditional ethylene oxide rigid chamber systems. Because EO-FCT removes excess air from the chamber, the system requires only a microdose of EO (17.6 grams) to achieve terminal sterilization. Rigid chambers can require up to 90% more ethylene oxide to achieve the same results.

Lethal to pathogens, EOGas 4PLUS is FDA-cleared to sterilize all flexible endoscopes, including those that have >1100 mm working lumens. This system is the first sterilizer to receive FDA 510(k) clearance for terminal sterilization of duodenoscopes and colonoscopes.

With EOGas 4PLUS, there’s no need to culture endoscopes. This system sterilizes and aerates in the same chamber and is able to terminally sterilize long lumens in just a few hours:

  • Six-hour gas exposure for two duodenoscopes or colonoscopes or one of each
  • One-hour ventilation
  • Length of aeration follows the manufacturer’s instruction for use (IFU)
  • Four-hour rapid-release BI incubation

EOGas 4PLUS systems are used around the world for processing medical instruments that, when processed using other modalities, become damaged and degraded. Equipped with two purge probes with process challenge devices (3- and 6-hour gas exposures, respectively), EOGas 4PLUS goes above and beyond, offering a low per-cycle cost, space-saving tabletop design and unparalleled compatibility. 

When combined with Andersen’s emissions abator, EOGas 4PLUS releases less than 0.02 grams of EO into the environment per cycle, making EOGas 4PLUS one of the most environmentally friendly systems on the market. EOGas 4PLUS has the same power requirements as a typical hairdryer.

EOGas 4PLUS is compact, effective, efficient and environmentally friendly, giving healthcare facilities a proven and reliable low-temperature gas sterilization option. EOGas 4PLUS  helps you protect your patients, especially young patients and those immunocompromised.
