   clavis key.]

      [1913 Webster]

   2. a device used for sterilizing objects by exposing them to
      steam at above atmospheric pressure (and thus at a
      temperature above the normal boiling point of water). It
      consists of a closed chamber able to withstand internal
      pressure, and a means of passing superheated steam into
      the chamber. Autoclaves are made in various sizes, and are
      much used in hospitals and research laboratories to render
      instruments and equipment sterile.
