A: VHP Passbox sterilizes at reduced temperatures employing vaporized hydrogen peroxide, contrary to standard steam sterilization that requires substantial heat. Refreshing sterile air or nitrogen is circulated just after decontamination. The H₂O�?vapor breaks down into drinking water and oxygen, reducing residual ranges to beneath one ppm—Harmless for operator entry. https://medium.com/@tailinscitech/vhp-sterilization-solutions-by-tailin-bioengineering-protecting-pharma-and-laboratory-environments-b515737bff96
