Andersen EOGas 4PLUS Ethylene Oxide Sterilizer (FDA-Approved).

Product code: NANEOG4Plus

FDA-cleared for complex endoscopes & longest lumens

The EOGas 4PLUS sets a new standard for reprocessing difficult-to-sterilize medical devices, including duodenoscopes and colonoscopes. Powered by EO-Flexible Chamber Technology (EO-FCT), it achieves terminal sterilization using a 17.6g EO microdose—up to 90% less EO than traditional systems. The system supports active aeration in the same chamber, controlled temperature circulation, automated door locking, and a user-friendly touchscreen interface. When paired with an optional ETO Cartridge Abator, it delivers zero-emissions performance, expanding sterilization capability for heat- and moisture-sensitive instruments.

Key Features:

FDA-cleared for terminal sterilization of complex long-lumen devices
EO-FCT technology using 17.6g microdose EO per cycle
Zero emissions when paired with Andersen abator
Efficient 3.5-hour cycle achieving 10⁻⁶ sterility assurance level
Active aeration in the same chamber (no device transfer required)
Touchscreen interface with real-time cycle guidance
Automatic door locking during sterilization cycles
Process Challenge Device built into purge probe for consistent BI placement

EOGas 4PLUS Advantage

Compared to Steam: Steam can damage heat-sensitive materials → EOGas 4PLUS preserves delicate devices
Compared to Hydrogen Peroxide (H₂O₂): H₂O₂ may degrade polymers and complex lumens → EOGas 4PLUS supports long-lumen compatibility
Compared to Traditional EO: Uses significantly less EO Lower emissions, smaller footprint, modern workflow

Features

Q. What is EOGas 4Plus
A. EOGas 4Plus is an advanced gas sterilization system designed for efficiency and reliability. It utilizes a microdose of ethylene oxide to ensure sterilization of medical instruments. This system is ideal for facilities seeking a reliable solution to sterilization needs.

Q. How does EOGas 4Plus work?
A. The EOGas 4 PLUS operates by introducing ethylene oxide gas into a impermeable flexible chamber containing the devices to be sterilized. The gas penetrates packaging and surfaces, effectively killing bacteria and viruses. After a designated exposure time, the gas is evacuated, leaving devices terminally sterile with a shelf life of up to six months.

Q. Is it safe to use?
A. The chamber wash pump flow rate is100 L/mn

Q. What devices is EOGas 4PLUS intended for?
A. Heat- and moisture-sensitive devices, including duodenoscopes, colonoscopes, and long-lumen instruments.

Q. Does it require a separate aeration cabinet?
A. No. Sterilization and active aeration occur in the same chamber.
