The cycle begins by lowering the isolator’s humidity under 30% relative humidity. Minimal moisture optimizes vapor generation and makes sure vapor can reach all surfaces, even very small crevices. This phase is very important for complete protection. Present day VHP passboxes incorporate various safety mechanisms such as hydrogen peroxide https://tailinscitech.wordpress.com/2026/02/09/vhp-sterilization-solutions-by-tailin-bioengineering-protecting-pharma-and-laboratory-environments/
