A hydrogen peroxide sterilization process includes H2O2 vapor filling the sterilizer chamber, making contact with and sterilizing uncovered machine surfaces. New sterile air or nitrogen is circulated just after decontamination. The H₂O�?vapor breaks down into water and oxygen, reducing residual concentrations to under one ppm—Secure for operator entry.
