osmo

n. [ Osmose + -graph. ] (Physics) An instrument for recording the height of the liquid in an endosmometer or for registering osmotic pressures. [ Webster 1913 Suppl. ]

n. [ Gr. 'wsmo`s impulse + -meter. ] (Physics) An instrument for measuring the amount of osmotic action in different liquids. [ 1913 Webster ]

n. (Physics) The study of osmosis by means of the osmometer. [ 1913 Webster ]

n. [ Gr. &unr_;, equiv. to &unr_; impulse, fr. &unr_; to push. ] (Chemical Physics) (a) The tendency in fluids to mix, or become equably diffused, when in contact. Same as osmosis, which see. [ 1913 Webster +PJC ]

Electric osmose, or
Electric endosmose (Elec.), the transportation of a liquid through a porous septum by the action of an electric current. [ 1913 Webster ]

n. [ NL., fr. Gr. 'wsmo`s, equiv. to 'w^sis impulse, fr. 'wqei^n to push. ] (Chemical Physics) (a) The tendency in fluids to mix, or become equably diffused, when in contact. It was first observed between fluids of differing densities, and as taking place through a membrane or an intervening porous structure. An older term for the phenomenon was Osmose. The more rapid flow from the thinner to the thicker fluid was then called endosmosis (formerly endosmose), and the opposite, slower current, exosmosis (formerly exosmose). Both are, however, results of the same force. Osmosis may be regarded as a form of molecular attraction, allied to that of adhesion. See also osmotic pressure. (b) The action produced by this tendency. [ 1913 Webster ]

a. Pertaining to, or having the property of, osmosis; as, osmotic force. [ 1913 Webster ]
