    • n cryophorus (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° Fahr.

    • n cryophorus An instrument for showing the fall of temperature in water by evaporation. One form consists of two glass globes united by a tube. Water is poured into one globe and boiled to expel the air, and while boiling the apparatus is hermetically sealed. When cool, the pressure of the included vapor is reduced to that due to the temperature of the surrounding atmosphere. The empty globe is then surrounded by a freezing-mixture, the vapor is condensed, and rapid evaporation takes place from the other globe, which is soon frozen by the lowering of its temperature.
