What is a Prevacuum Steam Sterilizer?

The prevacuum steam sterilizer was designed to help overcome the trapping of air in the chamber. Trapping of air is one of the greatest dangers encountered when using saturated steam under gravity cycles. When errors are made by improperly packaging items or overloading the sterilizer chamber, cool air pockets may form resulting in items not being sterilized. The speed and efficiency of the steam sterilizer may be improved by removing air from the chamber with a powerful pump, creating a nearly perfect vacuum before steam is introduced into the chamber. This procedure allows fast and more positive heat to penetrate the entire sterilizer load. The improved sterilizer is referred to as the prevacuum steam sterilizer. Full heating of the loads is faster in the prevacuum sterilizer than in the gravity displacement sterilizer. For example, wrapped instruments can be sterilized at 270°F (131°C) after 4 minutes exposure in a prevacuum steam sterilizer.
