autoclave1. a strong sealed vessel used for chemical reactions at high pressure 2. an apparatus for sterilizing objects (esp surgical instruments) or for cooking by means of steam under pressure 3. Civil engineering a vessel in which freshly cast concrete or sand-lime bricks are cured very rapidly in high-pressure steam Autoclave an apparatus for performing various processes under elevated temperatures and above-atmospheric pressure. The reaction is speeded up under these conditions, and the product yield is increased. Autoclaves may be rotary, rocking, horizontal, vertical, or columnar. If necessary, autoclaves can be provided with internal, external, or outboard heat exchangers; with mechanical, electromagnetic, or pneumatic agitating devices; and with instrumentation for measuring and controlling pressure, temperature, liquid fill level, and so forth. The design and basic parameters of a full-scale industrial autoclave vary widely, with capacities ranging from several dozen cm3 to hundreds of m3; autoclaves are designed to withstand pressures of up to 150MN/m3 (1,500 kgf/cm2) at temperatures of up to 500°C. Packless autoclaves driven by splashproof enclosed electric motors, requiring no seal, are promising for the chemical process industry. The rotor in this motor is mounted directly on the agitator shaft and is covered by an airtight, thin-walled enclosure of nonmagnetic material which does not prevent the magnetic lines of force from extending from the stator of the electric motor to its rotor. Autoclaves are used in the chemical industry in the production of herbicides and organic semifinished products and dyes and in synthesis processes; in hydrometallurgy for leaching with subsequent recovery from solutions of non-ferrous and precious metals and rare elements; in the rubber industry for vulcanizing rubber products; in the canning industry for sterilizing canned goods; and in the construction materials industry. Autoclaves are also widely used in medicine. REFERENCESKorndorf, B. A. Tekhnika vysokikh davlenii v khimii. Leningrad-Moscow, 1952.

autoclave [aw´to-klāv] a self-locking apparatus for the sterilization of materials by steam under pressure. The autoclave allows steam to flow around each article placed in the chamber. The vapor penetrates cloth or paper used to package the articles being sterilized. Autoclaving is one of the most effective methods for destruction of all types of microorganisms, including spores. The amount of time and degree of temperature necessary for sterilization depend on the articles to be sterilized and whether they are wrapped or left directly exposed to the steam.au·to·clave (aw'tō-klāv), 1. An apparatus for sterilization by steam under pressure consisting of a strong closed boiler in which are placed a small quantity of water and a wire basket holding the articles to be sterilized. 2. To sterilize in an autoclave.
