    Abstract: A centrifuge separation device is disclosed and includes a rotor (12) configured to be connected to a centrifuge motor (19) for rotation about an axis of rotation (13). A retainer (14) is associated with the rotor (12) and defines a passageway (14) for a separation channel (44). A protrusion (48) formed in one of the passageway walls (15, 16) extends towards and is spaced from the other of the passageway walls (15, 16). The protrusion (48) is sized to substantially block passage of materials in a predetermined density range and to substantially permit passage of materials outside of the predetermined density range. An indentation (51) formed adjacent the protrusion (48) in a wall of the passageway (14) opposite the protrusion (48) is configured to trap fluid during rotation of the rotor (12) and to cooperate with the trapped fluid to maintain a substantially Coriolis-free pathway in a region of the passageway adjacent the protrusion (48).

    Abstract: An apparatus and method are disclosed for filtering or separating particles. The apparatus has a centrifuge rotor (12) rotatable about an axis of rotation. A fluid chamber (22) rotates with the rotor. A substance is supplied to the inlet (28) of the chamber. A saturated fluidized bed of first particles forms within the fluid chamber and obstructs flow of second particles through the chamber. In an embodiment of the invention, additives substances alter sedimentation velocity of the first particles to modify the filtration characteristics of the saturated fluidized bed. The fluid chamber includes a wall extending between an inlet (28) and outlet (32) to form a fluid chamber interior. The interior converges from a position of maximum cross-sectional area toward the inlet. A groove or a step may be formed on an inner surface of the fluid chamber wall to improve particle separation within the fluid chamber.

    Abstract: Bag-system for centrifugal separation, comprising an outer, essentially ring-shaped outer bag (1) and a central inner bag (2) which is formed from the central part of the ring and preferably being detachable from the ring, and one or several connnecting channels between the interiors of said bags. According to the invention the bag-system has a rigid, circular centre part (16) on which the outer bag is mounted in a position for centrifugation, whereby the outer bag is given a conical shape around the centre part by means of a ring-shortened contraction of said bag. The inner bag is positioned in a cavity (17) in the centre part, which cavity is arranged to restrict the radial spreading of the inner bag but to allow an axial expansion of the inner bag when it is filled with a liquid. The invention also relates to the use of the bag-system for obtaining thrombocyte suspensions from buffycoat fractions by centrifugal separation and for recovering bone marrow cells from bone marrow suspensions by centrifugal separation.

    Abstract: A centrifuge apparatus is used for collecting white blood cells (WBC), primarily mononuclear cells, from whole blood stratified into layers. A thin mononuclear (MNC) layer is formed at the interface of red blood cells and plasma. A barrier is positioned in the separation vessel of the centrifuge at a location to intercept the thin layer. MNC fluid is allowed to pool behind the barrier before collection is started. To collect the MNC pool, the stratified red blood cell layer is raised from below the interface level by slowing or reversing flow in the RBC exit line thereby causing the MNC pool to spill over the barrier into a well in which a collect line is positioned. Collection ceases when a desired percentage of the pool is removed and the normal position of the interface is reestablished; thereafter the pool builds again. By raising the MNC pool from below, improvements in purity and collect volume are achieved. The collection procedure can be useful for harvesting granulocytes and, in general, any sparse stratified component of a centrifuged solution where the sparse component is layered between more dense and less dense strata.
