The proper time and temperature for dry heat sterilization is 160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour, and in the case of High Velocity Hot Air sterilisers, 190°C (375°F) for 6 to 12 minutes. [3] Items should be dry before sterilization since water will interfere with the process.
This method is a faster process than dry heat sterilization. Steam sterilization is performed using an autoclave , sometimes called a converter or steam sterilizer.

Sterilization using steam can also be done at a temperature of 132 C (270 F), at a double pressure. [citation needed] Dry heat sterilization is performed at 170 C (340 F) for one hour or two hours at a temperature of 160 C (320 F). Dry heat sterilization can also be performed at 121 C, for at least 16 hours. [17]
