摘要： A rotor for use in a centrifuge, and a method for balancing the rotor. The rotor includes a plurality of apertures arranged circumferentially around the rotor's axis of rotation, each configured to selectively receive a weight. A critical speed is determined for the rotor, and an imbalance determined for the rotor at a test speed below the critical speed. A trial weight is installed in a reference aperture, and another imbalance determined at the test speed. The trial weight is repeatedly moved to another aperture angularly displaced from the previous aperture, and the imbalance measured at the test speed until a predetermined number of imbalance measurements have been obtained. A target mass and location for balancing the rotor is determined from the imbalance measurements, and balancing weights installed in apertures based on the target mass and location. The balancing process may be repeated for multiple critical frequencies.

摘要： A rotor assembly (10, 150, 270, 310) and method of using the rotor assembly (10, 150, 270, 310). The rotor assembly (10, 150, 270, 310) includes a bio-process bag (48), a drum (46) that receives a lower portion of the bag (48), and a pressure ring (50). A holder (54, 182) couples an upper portion of the bag (48) to the pressure ring (50). The pressure ring (50) is coupled to the drum (46) to define an interior space that contains the bag (48). A liquid transport assembly (35, 178, 272) passes through an opening in the holder (54, 182) so that liquids can be added to, and removed from, the bag (48) without removing the rotor (16, 154) from the centrifuge. A bearing assembly (190) in the holder (54, 182) couples the liquid transport assembly (35, 178, 272) to the rotor (16, 154), and enables the liquid transport assembly (35, 178, 272) to remain stationary while the rotor (16, 154) rotates around it. One or more seal assemblies (276, 312) provide a fluid-tight seal against the outer portion of the liquid transport assembly (35, 178, 272), and prevent fluids from leaking from the bag (48) during centrifugation.
