Types of Dry Heat Sterilizers 1 Conventional Hot Air Oven Tunnel Sterilizers 45/29/2016 5. Less than 3% humidity produces what's called dry or superheated steam. At high temperature and pressure, impurities that get into the water from autoclave media can stick and burn to the autoclave heater, preventing the heater. Due to potential for charring and deterioration at high temperatures, their use is also questionable for dry-heat sterilization. This is typically achieved through the use of steam autoclaves, or via dry-heat ovens. • In general, for Dry Heat sterilization, Z-V alue may be assumed as 20 0 C. One way in which sterilization by way of irradiation may occur is when ionizing radiation is used. Describe the effects of microbial control agents on cellular structures. Sterilization failure may occur if residual air is not evacuated during the operation of the autoclave. Hot air oven is equipment that is highly prized for being used in pharmaceutical laboratories as well as other material testing labs.

Depending on the duration of heating and the temperature of heat, the effect of sterilization varies. The regularly improving awareness about the dry sterilization process among professionals associated with laboratories and research centers, the demand of laboratory hot air oven has been increased in the last few years. This means that a sterilizer becomes in effect, a dry-heat oven. Utilising hot air, which is free of water vapour (or contains only very small traces), this method accomplishes sterilisation via conduction. pressure in a steam autoclave, application of dry heat in a sterilizing oven and sterilization by chemical vapour. Dry heat is not as effective as moist heat in an autoclave. Dry heat = oven or tunnel Gas 1. The basic principle of steam sterilization, as accomplished in an autoclave, is to expose each item to direct steam contact at the required temperature and pressure for the specified time. Because the autoclave permits the attainment of high moist-heat temperatures and because heat exchange by steam is more rapid than by dry heat, this method of sterilization is more efficient than the dry-heat method. 1, Revised 2007, (TR 1) Validation of Moist Heat Sterilization Processes Cycle Design, Development, Qualification and Ongoing Control -www.
