A tube from a plurality of tubes from a tube rack configured to removably hold the plurality of tubes are removed from a tube rack. A weight of the tube which has been removed from the tube rack is determined. A balancing parameter of the tube is determined by a computing device. An estimated balancing parameter of each of a plurality of remaining tubes from the plurality of tubes in the tube rack is determined. A corresponding rotor position from a plurality of rotor positions within the rotor for the tube is determined by the computing device based at least on the balancing parameter of the tube, the balancing parameters of previously placed tubes from the plurality of tubes placed within the rotor and the estimated balancing parameter of each of the plurality of remaining tubes. The transport unit places the tube in the corresponding rotor position within the rotor.

An automatic processing device for liquid samples includes a sample region, a control module, an image identification device and a centrifuge. The sample region is configured to accommodate a plurality of centrifuge tubes. The control module includes a mechanical module. The mechanical module is configured to unscrew or tighten upper caps of the centrifuge tubes, and is configured to draw liquid from the centrifuge tubes or discharge liquid to the centrifuge tubes. The image identification device is coupled to the control module. The centrifuge is coupled to the control module. The centrifuge is configured to accommodate the centrifuge tubes and perform centrifugal treatment.

A centrifuge rotor assembly includes a chamber assembly, a bearing support, and a counterweight that is substantially diametrically opposed to the bearing support with respect to the chamber assembly. The chamber assembly receives a processing chamber of a fluid circuit, while the bearing support receives a portion of an umbilicus that is fluidly connected to the processing chamber. The bearing support and counterweight are rotated about a central axis of the chamber assembly by an electric drive of the centrifuge rotor assembly, with the bearing support and counterweight remaining substantially diametrically opposed to each other with respect to the chamber assembly while being rotated about the central axis. The electric drive may rotate the bearing support and counterweight at a plurality of different speeds, with the counterweight automatically moving with respect to the bearing support between radially innermost and radially outermost positions to balance the centrifuge rotor assembly.
