Dry heat sterilization is the process of sterilizing containers using hot air. Dry heat can take the form of still or convection. Still heating uses no blowers or moving air. Convection heating uses blowers or fans to keep the heated air moving, reducing the time it takes to heat the environment to the setpoint.
Moist heat kills the organisms by coagulating and denaturing their enzymes and structural protein. Sterilization by moist heat of the most resistant spores generally requires 121 Â°C for 15-30 minutes. Moist heat is used for the sterilization of culture media, and all other materials through which steam can penetrate. Moist heat is more effective than dry heat.
