Ethylene Oxide Flexible Chamber Technology:
The reliability of EtO using only 17.6 g/cycle
See how our exclusive EO-Flexible Chamber Technology.
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 occurs in the same chamber. There is no need to transfer products to a separate aeration area.

Using the EOGas 4 sterilizer
How EOGas 4 works
The sterilization bag and its components
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.
