OWNER’S MANUAL
4.2 ABRIDGED ILLUSTRATED INSTRUCTIONS
HOW ANPROLENE WORKS
7. EtO gas readily passes through cloth, paper, and Seal
and Peel
®
Packaging to reach the items to be sterilized.
8. The walls of the sterilization bag are also porous to EtO
gas. As the concentration of EtO gas in the liner bag is
increased by gas diffusing from the gas-release bag, the EtO
molecules also diffuse through the walls of the liner bag and
into the sterilization cabinet.
9. The EtO molecules diffusing from the liner bag into the
sterilization cabinet are then evacuated to the abator, if installed.
Any remaining effluent is then vented to the outside atmosphere
by the sterilizer’s ventilation system.
10. For about three hours there are more EtO molecules
released into the liner bag than are released by the liner bag
into the sterilizer. Then the rates are similar for three hours.
Finally, the liquid Anprolene in the gas-release bag is
exhausted. EtO molecules gradually diffuse into the sterilizer
for the remainder of the cycle.
11. At 12 hours, all items are sterile, and the residual gas in the
liner bag is small. The additional two-hour purge cycle is used
to remove remaining residual EtO from the liner bag before the
container may be opened.
12. Gas-absorbent materials, like plastic and rubber, are
aired in their protective wrapping before use. The EtO
gas absorbed by plastic or rubber readily escapes through
cloth, paper, or Seal and Peel

Packaging.
