What piece of equipment is used for sterilizing salon tools using steam?

Autoclave
Biohazard bin
High-frequency machine
UV sanitizer

The correct answer is: Autoclave

An autoclave is the only piece of equipment listed that uses steam specifically for sterilization purposes. A UV sanitizer may use heat, but it uses ultraviolet light rather than steam. A high-frequency machine and biohazard bin are not used for sterilization at all, but rather for other purposes such as treating skin conditions and disposing of hazardous materials, respectively.
