  • Patent number: 5653250
    Abstract: An apparatus and method for facilitating the attainment of thermodynamic equilibrium and for measurement of interfacial tension of mixtures. A fixed volume chamber is connected at an upper end face and lower wall portion of the chamber to a first variable volume chamber and at a lower end face and upper wall portion of the chamber to a second variable volume chamber. Conduit valves and a valve controller control the flow of mixtures between the first and second variable volume chambers and the fixed volume chamber to selectively cause more dense component of the mixture to flow through less dense component of the mixture and less dense component of the mixture to flow through more dense component of the mixture, the flow through occurring within the fixed volume chamber.
