What is an example of dry heat sterilization?
Then, what is dry heat method of sterilization?
It is the process of killing bacterial spores and microorganisms using a high temperature. This type of sterilization method is used on items that cannot get wet such as powders, oils, and the likes. Picture 1: An example of a dry heat sterilizer.
Also Know, what is the difference between dry heat sterilization and an autoclave? Autoclaving refers to a process of instrument sterilization that uses time, temperature and pressure to kill all forms of microbial life, whereas dry heat sterilization is basically sterilizing using an oven that uses time and heat to kill all forms of microbial life, including microbial spores and viruses.
Then, what materials can be sterilized using dry heat?
Materials that can be sterilized using dry heat
|Nylon (polyamide, heat-stabilized grades)||Up to 266°F|
|Paper||Up to 134°Cb|
|Perfluoroalkoxy||Up to 170°C|
How does dry heat kill microorganisms?
Dry heat helps kill the organisms using the destructive oxidation method. This helps destroy large contaminating bio-molecules such as proteins. The essential cell constituents are destroyed and the organism dies. The temperature is maintained for almost an hour to kill the most difficult of the resistant spores.
