Vertical autoclaves are cylindrical steam sterilizers used to sterilize medical equipment and supplies. They operate by opening the top loading door using a foot pedal, then using high pressure steam to sterilize items inside. Vertical autoclaves come in different models depending on the intended use and budget, including economy, deluxe, and triple walled stainless steel models. Fully automatic vertical autoclaves also exist to increase productivity through automated one-touch controls.
