autoclave

noun    (Concise Encyclopedia)

Vessel, usually of steel, able to withstand high temperatures and pressures. The chemical industry uses various types of autoclaves in manufacturing dyes and in other chemical reactions requiring high pressures. In bacteriology and medicine, instruments, equipment, supplies, and culture media are sterilized by superheated steam in an autoclave. In 1679 Denis Papin (1647–c. 1712) invented a prototype known as a steam digester; still used in cooking, it is now called a pressure cooker.
