High Efficiency Tabletop EO Sterilization
for the 21st Century
for the 21st Century
The temperature-controlled EOGas 4 cabinet along with Andersen’s bag and cartridge technology maximizes gas efficiency and minimizes gas usage;
only 17.6 g of gas per cycle.
Only 17.6g of Gas per Load
No more 50lb tanks!
EOGas 4 provides an optimal use of gas – thanks to its unique EO-FCT architecture.
EOGas 4 is gentler with the environment and with your pocket.
EOGas 4 requires minimal installation: just a 1″ PVC hose to the outside with the wall plate provided. There are no water or vacuum lines required. Sterilization and aeration happen in the same cabinet.
EOGas 4 Sterilizer
The EOGas 4 is a 50°C or 30°C cycle, tabletop cabinet with active aeration. Four cycles are available, the fastest being just 3.5 hours at 50°C, all delivering 10-6 SAL. Turn-around time for delicate medical items has never been this fast.
EOGas 4 compared to other low temperature sterilizers:
- The widest range of material and product compatibility (other than foods, liquids or drugs).
- Ability to sterilize long, narrow and multi-channel lumens.
- All sides and surfaces are sterilized; no “shadowing”
- Compatible with all common packaging materials.
- Will not damage delicate instruments like harsh chemical sterilants.
Ethylene Oxide Flexible Chamber Technology:
The reliability of EO using only 17.6g per cycle
See how our exclusive EO-Flexible Chamber Technology works.
EO-FCT uses active aeration to flush the sterilization bag with a constant flow of fresh air at the end of the sterilization cycle. Items that retain EO may require additional aeration. With EOGas, sterilization and aeration occur in the same chamber. There is no need to transfer products to a separate aeration area.

Using the EOGas 4 Sterilizer
The key feature of EO-flexible chamber system is the sterilization bag. The bag is the sterilization chamber. It keeps the use of gas at a minimum while ensuring the highest possible concentration.
The load and the 17.6g EO cartridge are placed in the sterilization bag. Standard sterility indicators (BIs) are used to ensure cycle success.
The sterilization bag and its components
The EOGas 4 refill kit comes with cartridges, liner bags, Humidichips and Dosimeters for 14 cycles. Each cartridge contains 17.6g of EO and the liner bag (sterilization chamber) holds up to 45 l. The EOGas 4 sterilizer requires this kit and only this kit.
Time, temperature and EO concentration are essential to successful sterilization. Dosimeter integrators present visual assurance that all these parameters have been fulfilled. View results immediately after sterilization. No laboratory culture is necessary. Use one Dosimeter per cycle. (Not a BI substitute).
Designed specifically for use with Andersen EOGas™ and Anprolene® systems, this unique device ensures adequate Relative Humidity (RH) during the sterilization cycle. Each single use pre-moistened 2″ x 2″ Humidichip releases up to 4 grams of water vapor.
