The Process of Dry Heat Sterilization Work
Dry heart sterilization takes longer than steam sterilization due to the inefficiencies of heating air with a very low moisture content. Compared to steam sterilization, which requires a temperature around 121 degrees Celsius to be maintained for approximately 30 minutes, dry heat sterilization requires higher temperatures of around 180 degrees Celsius to be effective at neutralizing biological contaminants and their spores. For this reason, dry heat sterilization is most appropriate for medical devices which are heat resistant but susceptible to water damage which would make steam sterilization a poor choice. Hot air ovens are the most common setup for dry heat sterilization of tools composed of metal or glass. Vials containing biologic drugs such as vaccines are often sterilized using a dry heat method prior to filling to ensure they contain no microorganisms. How does Dry Heat Sterilization Work? Dry heat sterilization uses high temperatures to kill microorganisms...
