What is the primary function of an autoclave?

• A. To sterilize equipment and materials using high-pressure steam
• B. To rinse instruments with tap water
• C. To store sterile supplies long-term
• D. To measure sterilization indicators

Answer: (A)

Autoclaves sterilize instruments and materials by exposing them to saturated steam under high pressure. The combination of high temperature and moisture denatures proteins and disrupts cell membranes, effectively killing all forms of microbial life, including resistant spores. This is why loads are wrapped and placed so steam can penetrate, and why cycles run at about 121°C (250°F) for a defined time with proper drying. Rinsing with tap water, storing sterile supplies, or simply measuring indicators do not achieve sterilization. Rinsing cleans but doesn’t kill all microbes; storage requires proper packaging and a controlled environment; indicators verify that a cycle occurred, but the device’s primary role is to achieve sterilization.
