12 Hour Exposure Cycle

Designed to achieve FDA-required 10-6 sterility assurance level for terminal sterilization of most medical devices.

17.6g EO Ampoule

Terminal sterility with 90% less EO than any other system on the market. Hermetically sealed glass EO ampoule protects from accidental activation..

Active Aeration in the Same Chamber

Andersen’s purge probe flushes the liner bag with a constant flow of fresh air at the end of the cycle – no need to transfer items to a separate area. Two hours of aeration standard. EO-absorbent items may require additional aeration. Active aeration continues indefinitely until products are removed.

Make Your System Zero Emissions

Andersen abators are a simple, cartridge-based system that employ a dry catalyst resin. The resin converts ethylene oxide to biodegradable organic compounds. Replaceable abator cartridge has a 200 cycle capacity. Spent cartridges are non-hazardous.

Smart Cabinet Design

A interior ventilation port in the back of the chamber actively draws fresh air from the room throughout the entire cycle. Ensuring air flow in one direction and minimizing potential operator exposure.

Easy Installation

Requires only a 120v or 240v outlet and a 1″ dedicated exhaust line.

Unmatched Compatibility

Anprolene’s 100% EO system sterilizes at room temperature without external vacuum lines or steam generator. Protects your most delicate instruments, electronics, drills, fiber optics, hand pieces and cameras. As well as those plastic, fabric, cellulose or rubber items that you can’t sterilize with other methods. Most any item with the exception of food, drugs or liquids can be sterilized with Anprolene.
