EtO Sterilization 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 17.6g of gas per cycle.
Our secret to high efficiency
Unlike traditional Ethylene oxide sterilizers which involve rigid metal chambers and large external tanks of gas, the EOGas 4 system uses gas-impermeable sterilization bags and unit dose 100% EtO cartridges.
By eliminating chamber dead space, EO-FCT employs only a tiny fraction of the EtO used in other systems.
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.
Only 17.6g of gas per load
No more 50lb tanks!
EOGas 4 provides optimal use of gas thanks to its unique EO-FCT architecture.
EOGas 4 is gentler with the environment and with your pocket
EoGas 4 Sterilizer
The EOGas 4 is a 50°C or 30°C cycle, benchtop cabinet with active aeration. Four cycles are available, the fastest being just 3½ 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.
EO-FCT Ethylene Oxide Flexible Chamber Technology
Small EtO Cartridge uses 80% less gas than other sterilizers
Adjustable cycle lengths
Sterilization and aeration cycles are fully adjustable to meet the needs of your specific loads
Small footprint and Easy Installation
Tabletop design requires only a 240v outlet and a 1" exhaust line.
The Sterilization Bag is effectively the sterilization chamber, increasing the efficiency of the sterilant
The Aeration in the same Chamber
There is no need to transfer products to a separate area
Ethylene Oxide Flexible Chamber Technology (EO - FCT): The reliability of EtO using only 17.6 g/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 EtO 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
EO-FCT Sterilization vs Traditional EtO Sterilization
True 10-6, 12-log sterilization
Small tabletop footprint
Only 17.6g of EtO per load
Easy Installation and maintenance
Operator training for the life of the sterilizer
Sterilization and aeration in the same chamber.
No need to wait for a large chamber to get full
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 EtO cartridge are placed in the sterilization bag.
Standard sterility indicators (BIs) are used to ensure cycle success.
The loaded sterilization bag is connected to the gas management system. This will extract most of the air from the bag while the sterilant is released. The opposite will happen once sterilization has been achieved. This process ensures a high gas concentration while minimizing the use of gas.

AN-1087 Chemical Indicator - EOGas Dosimeter 25 per box
Time, temperature and EO concentration are essential to successful sterilization. Dosimeter integrators present visual assurance that all these parameters have been fulfilled. Dosimeters change colour in proportion to the dose of sterilant they contact. View results immediately after sterilization. No laboratory culture is necessary. Use one Dosimeter per cycle. (Not a BI substitute).

Easy to use for every sterilization load
AN-1071 Humidichip® RH Stabilizer
Designed specifically for use with Andersen EOGas™ and Anprolene®, this unique device ensures adequate Relative Humidity (RH) during the sterilization cycle. Every single-use pre-moistened 2" x 2" Humidichip releases up to 4 grams of water vapour. Employ Humidchip® with a Humiditube™ in each sterilization cycle.
Ensures RH requirements for sterilization are met
The Humiditube™, developed to work with the Humidichip, allows air to circulate around the chip to help function properly.
