The principle of pre-vacuum pressure steam sterilizer?
The principle of sterilization: the use of mechanical vacuum to form a negative pressure in the sterilization cabinet, the steam can quickly penetrate into the interior of the article for sterilization. When the steam pressure reaches 205.8kPa (2.1kg/cm2) and the temperature reaches 132°C or above, sterilization begins. After the sterilization time is reached, vacuum is applied to quickly dry the sterilized items. According to the difference of one-time or multiple vacuuming, it is divided into two types: pre-vacuum and pulsating vacuum. The latter has more complete air removal due to multiple vacuums, and the effect is more reliable.
