Autoclaves typically operate at 121°C to 134°C, depending on sterilization cycle and load type.
A standard cycle takes 15–60 minutes, depending on temperature, pressure, and load size.
Yes, liquids can be sterilized using controlled heating and cooling cycles to prevent boiling over.
Pre-vacuum removes air completely, allowing steam to penetrate deeply into complex or wrapped instruments.
