Which of the following is a standard method of sterilization?

The use of an autoclave, or steam sterilization, is widely recognized as a standard method of sterilization in various healthcare and esthetic practices. This process involves using pressurized steam to kill all forms of microbial life, including bacteria, viruses, spores, and fungi. The effectiveness of steam sterilization is attributed to both the high temperature and the pressure produced inside the autoclave, which allows for thorough penetration of the heat and moisture.

Autoclaves typically operate at temperatures of 121-134 degrees Celsius (250-273 degrees Fahrenheit) and require specific exposure times, depending on the load being sterilized. The combination of heat, moisture, and time ensures a reliable sterilization process, making it the gold standard in many medical and cosmetic settings for eliminating pathogens on instruments and equipment.

While other methods like dry heat, ultraviolet light, and chemical agents have their uses, they may not consistently achieve the same level of sterility across various types of contaminants or materials. Dry heat sterilization requires significantly higher temperatures and longer times, making it less versatile. Ultraviolet light is primarily used for disinfection rather than sterilization and may not penetrate surfaces effectively. Chemical agents can be effective for certain applications but may not reliably eliminate all
