100% EtO Gas Diffusion:
The most effective sterilant, the most efficient
Ethylene oxide sterilizers which involve rigid
metal chambers and large external tanks of
gas, the Andersen EOGas system uses plastic
sterilization bags and unit dose 100% EtO cartridges.
By eliminating chamber dead space, EOGas employs
only a tiny fraction of the EtO used in other
The packaged items to
be sterilized are placed inside a sterilization
bag along with an EtO cartridge and a Humidichip®.
The bag is heat sealed and loaded into the sterilization
cabinet. Once inside the cabinet the EtO cartridge
is manually activated through the wall of the
sealed sterilization bag.

in two sizes; 35-Liter or 7 liter. Custom bags
sizes are also available. EOGas cartridge range
in size from 4 gram to 17.5 gram, and will be
selected as part of the validation process.
unique technology allows you to match each sterilization
load to the appropriate bag/cartridge combination,
and to adjust cycle length and temperature as
The sterilization cabinet acts as a heated aeration
chamber, maintaining a constant temperature (40
- 50oC) and drawing off the EtO as it diffuses
through the plastic of the sterilization bag over
the course of the 16 hour sterilization/aeration
cycle. Validated cycles may be shorter or longer
depending upon the product type.
cabinets vary in capacity from six to thirty
three cubic feet, and are designed to process
from three to twenty individual sterilization
EOGas cycles are validated using the applicable
portions of AAMI/ISO 11135.
