Abstract: The invention provides dual-skinned membrane useful as one way or rectifying membranes which reduce back filtration of solute molecules in dialysis and which improve nutrient supply and product recovery in membrane bioreactors. The membranes are dual-skinned polymeric materials preferably in the form of hollow fibers. The membranes have skins of polymer on the opposite sides with differing permeability to solutes and sieving coefficient characteristics. The skin on each side have pores that are invisible at 10,000 times magnification, the microporous structure between said skins contains pores capable of retaining solutes in a molecular weight range of about 5000 to 200,000 in an increased concentration between the interior and the exterior skins. Improved dialysis devices are formed by using bundles of the hollow fiber membranes as a dialysis means having rectifying properties.

Abstract: A centrifuge provides simplify access to the processing chamber. In one arrangement, the processing chamber separates into a bowl and spool element to receive a disposable processing bag. In another arrangement, the processing chamber pivots between an operating position and an access position to provide improved access. The centrifuge also employs readily accessible holders for releasably retaining tubing that, in use, conveys fluid to and from the chamber. Though greatly accessible, the centrifuge operates without the need of complicated rotating seals and expensive disposable components.

Abstract: A method of separating a selected component, such as platelets, using a centrifuge, comprises separating the fluid into components in three regions (104,106,198) and conveying fluid into the centrifuge while discharging components from the outer two regions through respective ports (50c,50b). Also during such discharge, the selected component is accumulated in the intermediate region 9108) and, after a predetermined volume of one of the other components has been discharged, discharging the third component through one of the ports (50b).
