Dry heat sterilization uses hot air to raise the temperature of an item to above a validated temperature which eliminates, removes, kills or deactivates biological contaminants and other biological agents on the object. These biological contaminants may include fungi, bacteria, viruses, spore forms and prions. The dry heat sterilization cycle is dependent on time and temperature, meaning as the temperature is increased the amount of time to achieve sterilization is decreased. The Dry Heat Sterilization Process Dry heat sterilization relies on heat conduction and heat convection. During the process, hot air sterilizers are used to heat up objects for decontamination
