ABSTRACT:
Apparatus for sterilizing laboratory and hospital glassware, liquids, instruments, garments and the like comprising a sterilizer enclosure having a steam jacket surrounding the same, a source of steam and means, connected in parallel, to supply steam to said jacket at one of two predetermined pressures, means for interconnecting said jacket and said interior of said sterilizer, and means responsive to a predetermined temperature setting for the interior of the sterilizer to selectively initiate and discontinue the supply of steam to said jacket in response to the temperature in said sterilizer. A process for sterilizing laboratory and hospital glassware, liquids, instruments, garments and the like comprising the steps of inserting the materials to be sterilized in a closed, sealed, jacketed sterilizer, introducing steam into the jacket of said sterilizer to preheat said jacket, interconnecting said jacket and the interior of said stabilizer initially to displace any air within said sterilizer, continuing to interconnect the jacket and the interior of said sterilizer; providing the jacket with steam at one of two different predetermined pressures; sensing the temperature within said sterilizer and introducing steam into said jacket at said higher pressure in response to said temperature sensitive means to maintain a variable, predetermined temperature within said sterilizer.
