Abstract: A blood bag cup, which is designed as a double cup with two individual cups with two separate chambers, one for accommodating the withdrawal and inflation bag and one for accommodating the satellite bag. The respective chamber for the satellite bags is preferably jointed. Advantages are an extremely high separation efficiency factor with maximum plasma yield with pure plasma and more than 50% time savings based on the doubled design of the double-chambered double cup.

Abstract: A device and a method for the separation of blood components in bags, as well as an associated blood bag cup. The device comprises a cup holder for a special double cup with two single cups and a double chamber each, whereby in one chamber of each of the two single cups at least one collection bag and at least one inflatable bag is inserted and in the other chamber of each of the two single cups at least one associated satellite bag connected via connecting hoses to the collection bag for the separated blood plasma is inserted. The device comprises a sensor for the detection of the separation layer between the separated blood components in the connecting hoses between the collection bag and the associated satellite bag. An extremely high degree of separation with e.g. maximum plasma yield, with purer plasma and time savings results.

Abstract: The invention relates to a closure for a centrifuge tube, the centrifuge tube comprising an essentially cylindrical neck which forms an opening which can be closed by the closure. The invention is characterized by a lid with a cylindrical rim portion overlapping the neck, a number of cutouts arranged in a distributed manner on the periphery of the rim portion and a number of radially outwardly facing projections arranged in a distributed manner on the outer periphery of the neck. The projections can be brought into engagement with the associated cutouts of the lid when the lid is put onto the tube, locking in the manner of a bayonet closure taking place by a rotary movement of the lid. The invention relates likewise to an arrangement of projections on the inner rim region and cutouts on the neck of the centrifuge tube.

Abstract: The present invention is a centrifuge essentially comprised of a rotor and a transparent cover which can be fixed to the rotor. The cover is provided with a plurality of spaced concentration lines each extending around the cover and a plurality of different graduated scales extending radially from the center of the cover across the concentration lines at spaced angular intervals. The rotor and the cover also have opposing snap lock elements at a central portion of the rotor and the cover.
