ABSTRACT:
A continuous flow electrophoretic separator (10) is provided, comprising a cylindrical stator (12) and a concentric tubular rotor (14), and electrode systems (24, 26) incorporated into the stator and the rotor defining between them an annular separation chamber (28). One or both electrode systems include a tubular semi-permeable membrane (56) supported by a support tube (58) of a rigid plastics material and grooved on its inner and outer surfaces. The grooves (64, 62) are deep enough to provide fluid communication between the two surfaces of the support tube, and those grooves (64) adjacent to the separation chamber are preferably less than 3 mm wide. If the membrane (56) is between the support tube (58) and the separation chamber (28), then the support tube (58) may have both longitudinal (60) and circumferential grooves (64) adjacent the membrane, and longitudinal grooves (62) on its other surface.
