Mastering Sterilization

Sterilization is a process that effectively kills or eliminates transmissible agents from a surface, equipment, foods, medications, or biological culture medium. It is used to prevent contamination and achieve aseptic conditions.

Dry heat has good penetrability and non-corrosive nature, making it applicable for sterilizing glassware and metallic instruments. It also destroys bacterial endotoxins that are difficult to eliminate by other means.

Under dry heat, oxidative changes take place, and higher heat input is required. These changes destroy microorganisms and achieve sterilization.
