Abstract: A dry sterilizer includes a container for containing beads, a heater, and a resilient member disposed adjacent to an opening of the container. An instrument, after sterilization, is tapped against the resilient member to remove beads attached to and lodged in the instrument and the removed beads are returned to the container. The resilient member prevents beads from entering a housing of the sterilizer by blocking a gap between the container and the housing at the opening.
