ABSTRACT OF THE DISCLOSURE To concentrate a material by separating it from a diluting medium, the combination of the material and medium is placed in one of two wells in the bottom of a plastic sample concentrator cell, with each well being closed at its bottom end by s different cellophane mem- brane in contact with a buffer solution in a different one of two buffer compartments. A buffer solution also connects the combination of material and medium in one well and the cellophane bottom of the other well within the sample concentration cell through a recess in the bottom of the sample concentration cell. A potential is applied across the two buffer compartments to cause the material to d grate by electrophoresis from the medium in one well, through the buffer in the sample concentrating cell and into the other well, where it is concentrated against the cellophane membrane for easy removal by pipetting.
