An autoclave is the device commonly used to sterilize equipment through the application of steam. It operates by heating water to create steam, which is then pressurized to achieve high temperatures that effectively kill bacteria, viruses, and other pathogens. This method is particularly effective because the combination of steam and pressure allows for thorough penetration of the steam into all surfaces and crevices of the instruments, ensuring that they are properly sterilized.

The autoclave functions at temperatures and pressures that are significantly higher than what can be achieved by simply boiling water or using other sterilization methods. This makes it a standard in many medical and beauty settings, where maintaining a sterile environment is crucial for safety and preventing infections.

In contrast, an incubator is designed to maintain a specific environment for the cultivation of microorganisms rather than for sterilization. A UV sterilizer uses ultraviolet light to reduce bacteria and viruses but does not achieve the same level of sterilization as steam under pressure. Lastly, a microwave sterilizer typically heats items unevenly and does not reliably kill all pathogens, making it less effective for sterilization purposes compared to an autoclave.
