All surgical instruments that are in touch with open wounds or enter the body of a patient
must be sterile. Therefore, all surgical instruments and materials have to be sterilized
before surgery. The machine which does the sterilizations is called autoclave or sterilizer.
If sterilization does not happen or happens insufficiently, life-threatening infections are the result.
For this reason the autoclave is one of the most important pieces of equipment in a hospital.
Hot air sterilizers are used to sterilize steel products to avoid rusting as against steam sterilizers
where water is used. They can also be applied for sterilization of products which cannot be sterilized
with steam like some plastics, papers, special liquids and powder.
The standard setting for a hot air sterilizer is
160°C (320°F) for 120minutes
190°C – 200°C (374°F-410°F) for 10 -12 minutes
