In a hot bead sterilizer, the temperature is highest in the inner zone of the sterilizer. A hot bead sterilizer uses a heated metal bead to transfer heat to the instruments, which are placed around the bead in a basket. The inner zone is where the bead is located and where the temperature can reach up to 300°C, which is sufficient to kill microorganisms and sterilize the instruments. The outer zone is cooler and does not contribute significantly to the sterilization process.
