预真空压力蒸气灭菌锅(简称预真空压力锅)是一种新型、先进的灭菌器具,它和国内目前普遍使用的下排气式压力灭菌锅,在性质上完全不同,杀灭菌的效果也大不一样。预真空压力锅消毒的原理是,用真空泵先将压力锅内空气抽尽后再消毒。而下排气式压力锅,消毒时锅内空气不排除,靠消毒蒸气进入锅内,挤压冷空气,经锅底排出。预真空压力锅消毒与下排气式压力锅消毒效果相比较,具有很多优点。
Pre-vacuum pressure steam sterilizer (hereinafter referred to as pre-vacuum pressure cooker) is a new type of advanced sterilization equipment, it is currently used under the prevailing pressure-type autoclave under the exhaust, completely different in nature, kill sterilization The effect is also very different. Pre-vacuum pressure cooker disinfection principle is to use a vacuum pump first pressure cooker air exhausted and then disinfected. Under the exhaust pressure cooker, disinfection of the pot when the air is not ruled out, by sterilization steam into the pot, squeezing cold air, discharged through the bottom of the pot. Pre-vacuum pressure cooker disinfection and under the exhaust pressure cooker compared to sterilization, has many advantages.
