Abstract: A rotor (10) for use in a centrifuge includes a rotor body (12), a drive hub (20), and a balance ring (16, 160). The rotor body (12) includes an elongated bore (32) extending along its axis of rotation (24), and an upper surface (26) having an annular groove (42). The drive hub (20) is mounted within the elongated bore (32), and includes a drive portion (138) having a cross-sectional shape that is complementary to the cross-sectional shape of the elongated bore (32). The drive hub (20) applies torque to the rotor body (12) via engagement of the drive portion (138) with the lower bore opening (36) of the rotor body (12). The balance ring (16, 160) is positioned in the annular groove (42), and includes a plurality of apertures (78, 163) formed in an upper surface (90, 170) thereof. Each of the apertures (78, 163) is configured to receive a weight (80, 164) so that the rotor (10) can be balanced by selectively adding weights (80, 164) to one or more of the apertures (78, 163).

Abstract: Embodiments of a single-tube rotor for a portable and compact centrifugal system are described. Embodiments include a monolithic rotor, suitable for manufacturing in a straight-pull injection mold, with an attachment hub, fixed retainer for exactly one sample tube, arms for the retainer, and a thin, aerodynamic counterweight. Embodiments include a counterweight and tube retainer angled downward; a central clearance volume for manual placement of a sample tube; and dimensions optimized to just fill a fixed rotational circle. Embodiments include a centrifuge with an enclosure, hinged lid, motor, and timer, free of both user controls and user displays.

Abstract: The present invention provides a centrifugal separator bowl (1) comprising a rotor casing (2) enclosing a separation space (17) in which a stack (19) of frustoconical separation discs is arranged to rotate around a vertical axis (X) of rotation, wherein the separation discs are arranged with the imaginary apex pointing to the axially lower end (5) of the rotor casing (2); a feed inlet (20) at the axially lower end (5) for receiving the fluid mixture to be separated; a distributor (24) for distributing the fluid mixture from the inlet (20) to the separation space (17), said distributor (24) being arranged for guiding the fluid mixture to be separated continuously from an axially lower position at the inlet (20) to an axially upper position in the separation space (17). The separator bowl further comprises a light phase outlet (21) for discharge of a separated phase of a first density and a heavy phase outlet (22) for discharge of a separated phase of a second density higher than said first density, said heavy phase outlet (22) being arranged at the axially upper end (6) of the rotor casing (2); at least one outlet conduit (23) for transporting separated phase of the second density from the separation space (17), said conduit (23) extending from a radially outer position of said separation space (17) to said heavy phase outlet (22); said conduit (23) having a conduit inlet (23a) arranged at the radially outer position and a conduit outlet (23b) at a radially inner position.

Abstract: Provided is a chamber configuration for a reverse flow centrifuge, and a reverse flow centrifuge system configured for low fluid volume and small radius rotation. The compact reverse flow centrifuge system has a reusable subsystem and a single use replaceable subsystem. The replaceable subsystem comprises a separation chamber, fluid delivery manifold and rotational mounting connecting the separation chamber to the fluid manifold. The single use replaceable subsystem provides a closed environment for execution of reverse flow centrifugation processes. The separation chamber has a substantially conical fluid enclosure portion connected to a neck portion, and a dip tube extends centrally through the conical fluid enclosure to provide a fluid path to the tip of the conical fluid enclosure.
