Approach to sedimentation equilibrium under gravity or in a centrifuge is much faster than usual if the solution or dispersion under study is contained in one compartment of a dialysis cell, while the other is filled with solvent. Osmosedimentation devices require large amounts of membranes, in various sizes and shapes. On the other side, these membranes are never subjected to large pressure differences, for which reason they do not have to be mechanically strong. Methods are described to prepare cellulose acetate membranes suitable for osmosedimentation work, along with data on their evaluation.
