Abstract
Solution and solvent reservoirs (30, 14) are separated by a solvent permeable membrane (54). A path (26) interconnects the reservoirs. Solvent vapor from the solution reservoir is created upon heat applied thereto for condensation (20) back to the solvent reservoir. A vent (56) extends from the solvent reservoir into the solvent vapor path so that the amount of solvent pumped through the membrane, which is determined by the level of solvent wetting the membrane, will equal the amount of solvent evaporated from the solution.
