Advantages And Disadvantages Of Dry Heat Sterilization And Moist Heat Sterilization
Due to the high temperature steam heat latent heat , penetrating power, easy or coagulation protein denaturation , thus the high efficiency of the method of sterilization than dry heat sterilization .
There are three reasons : ① coagulation proteins related to the temperature required for its water content , the greater the water content , the lower the temperature required for coagulation . Moist heat sterilization of bacterial proteins absorb moisture , so dry compared to the same temperature as the hot air is easy to set.
② moist heat sterilization process steam release a lot of latent heat , and improve humidity. Thus the desired heat than dry heat sterilization temperature is low , as at the same temperature, the heat than dry heat sterilization time is short .
③ heat penetration than dry heat large, it can reach deep sterilization temperature , the thermal effect is better than dry heat .

In addition, from the use of perspective, heat sterilization is generally controlled 90 ° C can be achieved in a very thorough disinfection , the entire disinfection process all attachments are not removed within the incubator , can all be disinfected ; rather dry heat sterilization in order to achieve more good results, temperatures are generally in the 100 ° C or more, must be taken during the sterilization process in which the temperature sensor , HEPA filter sterilized inside the incubator , etc. , etc. disinfected and then loaded on the end , so that trouble, accessories and can not be disinfected , but also increases the chance of secondary pollution Moreover to reach temperatures above 100 ° C incubator heating wire heating system is bound to bold , which leads to increased difficulty in controlling the temperature of the incubator , uniformity becomes poor.
