The plasma sterilizer’s work principle is that the hydrogen peroxide low-temperature plasma contacts with multiple microorganism’s cell wall and cell membrane on surgical apparatus, oxidize and inactivate them so as to achieve the sterilization effect. This sterilizer is used in the sterilization of equipment that is resistant to high temperature and damp heat. This low-temperature sterilization system is a low-temperature plasma sterilizer to inactivate microorganisms for a broad range of metal and nonmetal medical devices and surgical instruments at low temperatures. The compact size sterilizer can disinfect medical devices by diffusing hydrogen peroxide vapor into the chamber or pouch.
