    Abstract: The present invention briefly concerns a centrifugal rotor for laboratory centrifuges, comprising a disk (1) and a cover (10), whereby a ring-shaped carrier (5) of capillary tubes (9) is attached to the bottom of the disk (1). The disk (1) has at its outer periphery an axially projecting flange (3) which is inclined relative to the axis of rotation of the centrifugal rotor, so that any liquid escaping out into the centrifugal rotor is urged by the centrifugal force to the ring-shaped, circular edge (20) formed between the flange (3) and the bottom (2, 17) of the disk (1). Preferably, the cover has a peripherally outer portion with a step in the form of an axially extended portion (13). which continues in a radially ring-shaped edge portion (14), the axially extended portion (13) having a height greater than the thickness of the folded-back portion (4) of the axially projecting flange of the disk (1) and a gasket ring positioned thereon.

    Abstract: A continuous flow centrifuge system having a disposable fluid container of constant cross-section mounted in a circular channel. The channel, defining a separation region, has a constant height and side walls of divering spirals to increase the cross-sectional area from inlet to outlet. The container expands dynamically to conform to the claimed geometry and the collection chamber is attached to the container to obtain the separated fluid fractions. The channel may be in an insert, defined between the walls of the insert and the rotor bowl or in a rotor head assembly.

    Abstract: Analyseeinsatzelement (16) für die Rotoreinheit (10) eines Zentrifugalanalysators zur analytischen Bestimmung mindestens eines Bestandteils einer Probenflüssigkeit.
    Es enthält mindestens ein vorgespacktes Reagenz, das während der Rotation der Rotoreinheit (10) mit der Probe vermischt wird. Halterungsteile (42) sind zur Halterung an der Rotorbasis (12) der Rotoreinheit (10) vorgesehen. Eine Meßkammer (84) dient zum Messen eines für den Nachweis von Bestandteilen der Probe charakteristischen Parameters.
    Eine besonders einfache Bedienung, flexible Nutzung und zugleich zuverlässige Funktionsweise des Zen trifugalanalysators wird dadurch erreicht, daß das Einsatz element Kammern (29) für die Aufnahme der Probenblüssig keit und Fluidkanäle (86) zur Verbindung der Probenkammern (29) mit den Meßkammern (84) aufweist, daß die Fluidkanäle (86) mindestens ein vorgepacktes Reagenz enthalten und daß die Halterungsteile (42) dergestalt ausgebildet sind, daß das Analyseelement auf der Rotorbasis (12) des Rotors (10) im Betrieb positionsstabil in einer solchen Position gehalten wird, daß die Probenkammern (29) radial einwärts von den Meßkammern (84) liegen, so daß die Probenflüssigkeit von den Probenkammern (29) bei Drehung des Rotors unter Ein wirkung der Zentrifugalkraft durch die Fluidkanäle (86) in die Meßkammern (84) getrieben wird, wobei es mit dem Reagenz in Kontakt gebracht und mindestens teilweise vermischt wird.

    Abstract: Centrifuging apparatus 2 has a plate 10 disposed adjacent a flexible whole blood bag 8 in which blood is being processed. Under the influence of centrifugal force the plate 10, which is disposed inwardly nearer the center of rotation than the bag 8, expels a separated blood component from the bag into a receiver bag 6. The bag 6 is located radially outward from the bag 8 and a valve 117 (see Figure 6) is provided which is responsive to the specific density of separated components to stop the flow. The mass of the plate 10 may be selected so as to expel only the desired component. A further separated blood component is similarly expressed into radially outermost bag 4. Timer mechanism 15 automatically clamps the intermediate flow tubing (52, 54). A plurality of embodiments are described useful for plasma pheresis, platelet pheresis and cell-washing. The receiver bag 6 may be positioned radially inward of bag 8 or circumferentially along side it. The apparatus minimises the pressure to which blood processing bags are subjected and provides for automatic displacement of separated components and automatic termination of flow within the confines of the rotor.

    Abstract: A long, thin annular belt-like channel is designed for use in sedimentation field flow fractionation. This channel, which is the rotor of a centrifuge, is designed to maintain its thickness dimension constant and yet facilitate its manufacture and cleaning by forming the rotor of a double mating ring in which the inner ring 58 is split at 60. This permits the inner ring 58 to conform to the outer load carrying ring 56. The channel is defined by groove 70 and the inner ring is urged against the outer ring 56 by wedges 69. Ports 12 and 14 give fluid access to the channel 70.

    Abstract: An ultracentrifuge rotor is characterized by a hub having radially outwardly extending curved spokes. The outer ends of the spokes are received in a groove defined on the inner peripheral surface of an annular rim. Sample carriers are affixed to the rim at circumferentially spaced locations defined between adjacent pairs of spokes. As the rotor rotates the disparity in physical properties between the hub and the rim as well as the flattening of the curvature of the spokes causes the hub to grow to an extent at least equal to that of the growth of the rim.
