By utilizing of the ability of VHP can kill spores effectively at normal temperature, achieving the purpose of surface sterilization of the

transferred material. Under the protection of clean air flow, double door interlock function, it can prevent secondary cross

pollution effectively and prevent microorganisms being carried into aseptic cleanroom to realize the safety transition.

◆ Using VHP as biological detergent can kill fungus germ, bacteria and virus effectively. VHP is a decontamination technology at state

of low temperature and atmospheric pressure. It is widely usage, environment protection and high efficiency.VHP sterilization method is
