    Abstract: An apparatus and method are provided for separating components of a fluid or particles. A separation vessel (28) having a barrier dam (62) is provided to initially separate intermediate density components of a fluid, and a fluid chamber (30) is provided to further separate these intermediate density components by forming an elutriative field or saturated fluidized particle bed. The separation vessel includes a shield (96) for limiting flow into the fluid chamber of relatively high density substances, such as red blood cells. The separation vessel also includes a trap dam (70) with a smooth, gradually sloped downstream section (104) for reducing mixing of substances. Structure is also provided for adding additional plasma to platelets and plasma flowing from the fluid chamber. The system reduces clumping of platelets by limiting contact between the platelets and walls of the separation vessel.

    Abstract: A centrifugal evaporator, in which inclined sample tubes (61) supported in a holder (62) are rotatably mounted on a rotor (64), within a vacuum chamber (76), has a rotatable drive shaft (63) connected to the holder. Drive to the shaft (63) is via a spindle (70) passing up through the centre of a main drive shaft (71) and connected by bevel gears (67), (69) to the shaft (63). In operation, the relatively slow rotation of the holder (62) mounted on the shaft (63), in combination with rotation about the main shaft (71), causes the liquid sample in each tube (61) to be swept around the inside walls of the tube to simulate a vortex, thereby increasing the exposed surface area and improving evaporation. In an alternative arrangement the holder is pivoted relative to the rotor, so that the liquid sample is alternatively slushed from one side wall to the other.

    Abstract: A system for separating biological fluids into components, comprises a set of containers (40, 42-44) for the biological fluid to be separated and the separated components, optionally an additional container (41) for additive solution, and a hollow centrifugal processing chamber (20) having an axial inlet/outlet (7) for the biological fluid. The processing chamber contains a piston (21) movable to intake a selected quantity of biological fluid and express processed biological fluid components via the outlet. Optical means (60-69) monitor the position of piston (21) to control the amount of intaken fluid and the expression of components. A distribution valve arrangement (45-48) selectively communicates the processing chamber (20) and the containers (40-44) or places them out of communication. The system is arranged to operate in a separation mode and in a non-separation transfer mode, especially for adding preservative solution to separated blood stem cells. In the separation mode, fluids are intaken into processing chamber (20), centrifuged and separated into components, and the components expressed possibly through the use of a density gradient product. In the transfer mode, the processing chamber (20) intakes and expresses fluid with the chamber stationary, the valve actuation arrangement (45-48) transferring fluid from one container (40-44) to another via the processing chamber (20), by movement of the piston (21), without centrifugation or separation, and the means (60-69) for monitoring the piston's position controls the amounts of non-separated fluids transferred.

    Abstract: Centrifuge apparatus comprises a rotor (20) having an axis of rotation (22) and a sample holder (24), the longitudinal axis (28) of the sample holder being oriented to extend along a chord of a circle defined by the rotational path of the perimeter of the rotor, the chord being spaced from the axis of rotation by as great a distance as possible. The sample holder may be fixed relative to rotor, but is preferably movable during operation of the apparatus such that the angle between the centrifugal force direction and the longitudinal axis may be varied in a predetermined manner whilst the apparatus is operating at effective centrifugation speeds, said angle being controlled by a biassing mechanism (32). A similar biassing mechanism may also be applied to an otherwise conventional "swinging-bucket" type centrifuge. The apparatus provides improved speed and uniformity of centrifugation.

    Abstract: The instant invention relates to a method and the apparatus for collecting a hyperconcentrated platelet product. A fluid containing platelets and other particles flows into a fluid chamber at a flow rate. The flow rate of the fluid is selected to retain the majority of the platelets in the fluid chamber in a saturated bed. The platelets are collected from the fluid chamber without collecting the other particles to form a hyperconcentrated other particle reduced platelet product.

    Abstract: A system and method are disclosed for separating particles having different sedimentation velocities. The system includes a fluid chamber for separating the particles from one another. Conduits are provided for flowing liquid carrying particles to the fluid chamber and for mixing the liquid with a diluting liquid. Structure is also provided for separating particles from the liquids after the particles are separated in the fluid chamber. The disclosed methods include forming a saturated fluidized bed of first particles to retain second particles in the fluid chamber. A diluting liquid having a density less than that of the particles is mixed with the liquid carrying particles to reduce overall density of substances in the fluid chamber and thereby reduce Coriolis jetting of liquids in the fluid chamber.
