pharmaceutical cleanroom workshop GMP standard VHP sterilization

Vaporized hydrogen peroxide has a good effect on killing bacterial spores. As a disinfection and sterilization medium, hydrogen peroxide with a concentration of 35% is vaporized by a VHP generator to disinfect and sterilize the sterilized material. Experimental results have shown that the ability of vaporized hydrogen peroxide to kill bacterial spores is stronger than that of liquid hydrogen peroxide of the same order of magnitude: the sterilization effect of vaporized hydrogen peroxide at concentrations of 750-2000 μ g/L is equivalent to that of liquid hydrogen peroxide at concentrations of 300000 mg/L. Low concentration sterilization also correspondingly reduces the material requirements and costs of the disinfected surface. The temperature range for sterilization with vaporized hydrogen peroxide can be adapted between 4-80 ℃, usually room temperature is sufficient. During the disinfection and sterilization process, vaporized hydrogen peroxide is reduced to water and oxygen. Compared
