This Rectangular Pulsating Vacuum Sterilizer Autoclave uses saturated steam as the sterilization medium, which would completely penetrate into the surface of the articles through pulsating vacuum, and all the microorganisms and their spores would be killed by it under high pressure. It is the most reliable and effective method in physical sterilization. Pulsating vacuum exhaust eliminates the influence of cold air on temperature, finally, the sterilizing articles are dried by vacuum dehumidification combined with a jacket.
