The Fundamental Difference Between Moist Heat Sterilization And Dry Heat Sterilization

Moist heat and dry heat factors are the use of heat to kill microorganisms physical sterilization methods , but their different sterilization mechanism , i.e. primarily through the moist heat coagulation of protein caused the death of microorganisms , dry heat dehydration by law drying the protein oxidation, denaturation, carbonization and electrolyte concentrate poisoning leaving microbial death .

Their operating characteristics are different, the fundamental difference is that when the sterilization treatment, environmental and microbial cells heated humidity levels differ: ” heat ” heating means heating the internal microbes in this environment are in the humidity and heat saturation in this case microorganisms and pure water or saturated steam was equilibrium ; Check more news on http://www.autoclavesale.com/ site .while ” dry heat ” heating , heating environment is used to refer to water or enough to reach saturation under heat and humidity , the humidity level can be zero , or just below saturation.

Dry heat sterilization on poor penetration dish plus iron , it is not recommended to be dry heat sterilized Petri dishes , and a large -capacity glass containers are not suitable for moist heat sterilization . Overall : 500ml large capacity of more than thicker glass and glass bottles are not suitable for moist heat sterilization , dry heat sterilization can be used , the effect is more ideal , but the dish is moist heat sterilization is better, small capacity glass bottles and glass bottles thinner two methods can be used.
