Which piece of equipment relies solely on high pressure and heat or steam to prevent the survival of microorganisms?

An autoclave is designed specifically to use high pressure and steam to achieve sterilization. This process involves heating water to produce steam, which is then pressurized to a level that effectively kills bacteria, viruses, fungi, and spores. The combination of elevated temperature and pressure ensures that even the most resistant microorganisms are eradicated, making the autoclave a critical tool in settings where sterilization is essential, such as medical and esthetic practices.

In contrast, a UV sterilizer uses ultraviolet light to disinfect surfaces and equipment, but it does not apply heat or pressure. A sanitization station generally refers to areas where cleaning or sanitizing products might be used, but it does not function under the same principles of high heat and pressure for sterilization. A cool mist humidifier is used to add moisture to the air and does not have any sterilization capabilities. Therefore, the autoclave stands out as the only equipment capable of relying solely on high pressure and heat or steam to ensure the complete destruction of microorganisms.
