Root Explanation

Autoclave is formed from "auto-" (meaning self) and "clavis" (from Latin, meaning key). The term refers to a device that uses steam under pressure to sterilize equipment, effectively acting as a self-locking chamber for the sterilization process.

Memory Tip

Think of 'self' ('auto-') and a 'key' ('clavis') that locks in the steam to sterilize. This helps you remember that an autoclave is a self-locking device for sterilization.
