Abstract
A multi-channel separation device is provided for use in separation technology, particularly in electrophoresis and in isoelectric focusing. The device includes two mating plates, at least one of which contains an array of at least three cavities arranged to define a serpentine fluid pathway through the cavities when the plates are mated. Each of the cavities includes fluid input and output ports to facilitate transfer of process fluid through the cavities. A septum is disposed between the plates for streamlining fluid flow between the input and output ports by restricting but not preventing free fluid flow between adjacent cavities. The device also includes anodic and cathodic compartments containing electrodes for establishing an electric field across the cavities.
