Vapour Hydrogen Peroxide Generator is specially designed device for sterilization in enclosed spaces such as isolation room, isolator, transfer passageway, blending machine, biosafety cabinets and in small clean room. It takes the advantages of the hydrogen peroxide has better sporicidal efficiency in gas state than the liquid state at room temperature and then generated free hydroxyl groups are this to attack cell components, including lipids, proteins and DNA organization, which achieves the requirement of complete sterilization.
