The vertical counter-pressure rapid cooling sterlizer uses saturated steam as the sterilization medium, discharges the air in the cavity through gravity displacement, and uses saturated steam to kill allmicroorganisms under high pressure, The unique top-pressure water cooling system can achieve rapidcooling after sterilization. The sterilizer is suitable for the sterilization of items such as liquid loads, media, tissue culture and wastewhich require high sterilization requirements. * Stainless steel main structure: High- quality stainless steel main material combination, corrosion resistance, easy maintenance, long life. * Quick- opening structure: Horizontal sliding quick- opening structure, self- expanding seal, simple operation. * Built- in a variety of programs: Built- in liquid load, media and other sterilization programs. *Intelligent control system: Microcomputer program automatic control, LCD screen display working status, touch key. * Back pressure protection system: The cooling stage through the external compressed air, to ensure that sterilized items are effectively protected. * Rapid cooling system: Brand new water cooling system, rapid cooling in 3 minutes, lowering the inner room temperature by 30~40″C. * Power off hold system: Power off hold function, after reconnecting the power, automatically resume from the program break point. * Safety protection system: Over- temperature protection, anti- dry burning protection, door safety inter lock, automatic pressure relief.
