Many autoclaves are used to sterilize equipment and supplies by subjecting them to pressurized saturated steam at 121 °C (250 °F) for 30–60 minutes at a pressure of 103 kPa [1] (about double atmospheric pressure) depending on .In summary, the difference between a 121°C and 134°C autoclave is the temperature and time required for sterilization. Choosing the higher temperature can save time, but it is important to .
