The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder (42), a pump (64) and a plurality of valves (1-11) configured to at least partially control fluid flow through a fluid circuitry and a separation column (40) positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.

A method for processing particles contained in a liquid biological sample is presented. The method uses a rotatable vessel for processing particles contained in a liquid biological sample. The rotatable vessel has a longitudinal axis about which the vessel is rotatable, an upper portion comprising a top opening for receiving the liquid comprising the particles, a lower portion for holding the liquid while the rotatable vessel is resting, the lower portion comprising a bottom, and an intermediate portion located between the upper portion and the lower portion, the intermediate portion comprising a lateral collection chamber for holding the liquid while the rotatable vessel is rotating. The method employs dedicated acceleration and deceleration profiles for sedimentation and re-suspension of the particles of interest.

A centrifugal mechanical separator comprises a disk stack formed by an additive manufacturing process (i.e., 3D printing), where the stack comprises a plurality of disk elements (which may range anywhere from a few to a few hundred). The disk stack is positioned within a proper-sized bowl (with proper inlet and outlet ports), which may also formed using an additive manufacturing process. A bowl cover and inlet/outlet assembly may also be formed using additive manufacturing, where the various dimensions and tolerances of each component (disk stack, bowl, bowl cover, and inlet/outlet assembly) are carefully controlled by the additive manufacturing process, reducing the costs and complexities associated with traditional centrifuge manufacture.

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.

According to an embodiment, a centrifugal separation apparatus includes, a centrifugal separator comprising a retainer and a rotating member for rotation of the retainer, the retainer adapted to retain a workpiece, an imaging unit configured to acquire a detection image of an installation position at which the retainer is placed, a transfer mechanism configured to move the workpiece into the centrifugal separator, and a sensor processing unit configured to detect, based on the detection image acquired after an installation process of placing the workpiece into the retainer and before a rotation process of rotating the rotating member, a state of the workpiece subjected to the installation process.

A fixed-angle rotor for centrifuges includes stiffening ribs on the lower side of its rotor body. Its rotational energy is comparatively low during operation even at high speeds, whereby safety is noticeably increased without the need for a reinforced armored vessel in the centrifuge that is equipped therewith. At the same time, the drive power required to drive the fixed-angle rotor remains low. The fixed-angle rotor also withstands extreme loads over a long period of time. In addition, the fixed-angle rotor can be manufactured cost-effectively, because no additional components are required; rather, the stiffening ribs can also be manufactured during the manufacture of the rotor body. Finally, very thin rotor shells can also be used, which improves the temperature control of the samples, because the fixed-angle rotor has very good structural stability, especially in the main load directions.

A rotor for use in a centrifuge, and adapters for coupling one or more processing containers to the rotor. The rotor includes a rotor body having a plurality of receptacles each configured to receive an adapter. Each adapter includes an outer surface configured to interface with one of the receptacles, and one or more cavities each configured to accept a processing container. The rotor may also include a rotor liner positioned between the adapters and the rotor body. The rotor liner engages the receptacles of the rotor body, and provides a plurality of receptacles that receive the adapters, thereby providing an interface between the adapters and the receptacles of the rotor body.
