What equipment is commonly used to achieve sterilization?

The correct choice, which is the autoclave, is a specialized device designed specifically for sterilization processes. It works by using high-temperature steam under pressure to eliminate all forms of microorganisms, including bacteria, viruses, fungi, and spores. The combination of heat and pressure in an autoclave effectively penetrates materials like surgical instruments, ensuring thorough sterilization. This makes it an essential tool in healthcare settings, laboratories, and any environment where sterility is critical.

In contrast, a refrigerator is used to preserve food and slow microbial growth but does not achieve sterilization. A microwave heats food through radiation and can reduce microbial load, but it does not ensure complete sterilization due to uneven heat distribution and insufficient temperatures for killing all pathogens. An incubator is used for cultivating and maintaining microorganisms at specific temperatures but is not involved in the sterilization process. Each of these alternatives serves specific functions but falls short of the rigorous requirements needed for true sterilization that the autoclave provides.
