What type of sterilization method uses high-pressure steam?

The method that utilizes high-pressure steam for sterilization is autoclaving. This process involves placing instruments or materials in a chamber and exposing them to steam under pressure, typically at a temperature of about 121-134 degrees Celsius. The combination of steam and increased pressure effectively destroys all forms of microorganisms, including spores, making autoclaving one of the most reliable methods of sterilization in healthcare settings.

Autoclaving is particularly favored because it is fast, efficient, and safe for heat and moisture-stable materials. The process ensures that the items being sterilized are not only free of contaminants but are also preserved without any toxic residues that some other methods may leave behind. This makes autoclaving the gold standard in sterilization practices for surgical instruments and laboratory equipment.
