Abstract
Apparatus for sterilizing laboratory and hospital glassware, liquids, instruments, garments, contaminated animal wastes and bedding and the like, utilizing a sterilizer enclosure having a steam jacket surrounding the same and a vertically movable front door closure, wherein the door is vertically slideable in a track and is substantially restrained from outward movement by restraining means only at its upper and lower end, and including expandable seal members surrounding the sterilizer opening and opposite the door. The seal comprises two discrete segments, an inflatable member for displacing the sealing member against the door in sealing relationship therewith, and a sealing member. The construction is designed for maximum safety and ease of operation at minimum cost.
