The MD series is a pulsating vacuum sterilizer that uses saturated steam as a medium. This allows saturated steam to completely penetrate the surface of objects through vacuum pulsation, and uses high-pressure steam to destroy all microorganisms and their spores, which is the most effective and reliable method of physical sterilization. Eliminates the effects of cold air or temperature by using a pulsating vacuum, and eventually performs vacuum dewatering with combined drying using a shell for sterilized items.
