Abstract
The disclosure is directed to an apparatus for isoelectric focusing. A fluid is employed which contains buffering compounds capable of establishing a pH gradient in an electric field. A plurality of ion non-selective permeable membranes are used to streamline the flow of fluid while allowing interchange of fluid constituents therebetween. Electrodes establish an electrical potential transverse the flow of fluid to establish a gradient of pH steps as between successive channels defined by the membranes.
