What machine is primarily used for steam sterilization in medical settings?

The autoclave is the machine primarily used for steam sterilization in medical settings because it uses pressurized steam to kill bacteria, viruses, and spores. The process involves heating water to create steam and then increasing the pressure, which raises the boiling point of water and allows for the effective destruction of microorganisms. This method is highly reliable and is considered the gold standard for sterilizing surgical instruments, laboratory equipment, and other items that can withstand high temperatures and moisture.

In contrast, an incubator is utilized to provide a controlled environment for the growth of microorganisms or cells, rather than for sterilization purposes. An ultrasonic cleaner uses high-frequency sound waves to remove debris from instruments but does not provide sterilization. An oven sterilizer operates through dry heat and is effective for certain materials but does not offer the same efficiency in killing heat-resistant spores as steam sterilization achieved by an autoclave.
