   fr. Gr. kry`os icy cold, frost + fe`rein to bear.] (Chem.)
   An instrument used to illustrate the freezing of water by its
   own evaporation. The ordinary form consists of two glass
   bulbs, connected by a tube of the same material, and
   containing only a quantity of water and its vapor, devoid of
   air. The water is in one of the bulbs, and freezes when the
   other is cooled below 32[deg] Fahr.
