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.

A determination mechanism which obtains information about the weight of the specimen housed in the specimen container is arranged on a conveyor line for connecting between a loading module and an automatic centrifugal unit, the specimens are held without being installed at an adaptor until the number of the specimens which can be subjected to a centrifugal processing at once by the automatic centrifugal unit arrives, and the specimens are installed after the arrival in an order from a heavier specimen at the adaptors to be paired, which are installed at the symmetric positions to each other across the rotation central axis. Also, the specimen is installed at the gravity-center position of the adaptor first, and the subsequent specimens are installed from the inner side at the point-symmetric positions to each other across the gravity-center position.

The invention relates to a centrifuge rotor with two centrifuge rotor parts. In the assembled state, the centrifuge rotor parts delimit an inner chamber in which a product to be centrifuged can be arranged. According to various embodiments, the centrifuge rotor parts are connected to each other or can be connected to each other by a locking device. The locking device is actuated and/or is biased towards a locking position by means of a centrifugal force as a result of the rotation of the centrifuge rotor.

A control method and a non-transitory computer-readable storage medium are provided. The control method includes: obtaining the number of detection cards; determining a strategy for rotating a card holder of a multi-flux centrifugal platform, wherein the strategy corresponds to the number of the detection cards; controlling the card holder to rotate according to the strategy, and exposing a card position of the card holder at a card placement port.

The invention relates to a centrifuge (10), in particular a laboratory centrifuge, comprising a rotor (12) for receiving containers with material to be centrifuged, a drive shaft (14) on which the rotor (12) is supported, a motor (18) which drives the rotor (12) via the drive shaft, a bearing unit (30) with damping elements (36) each having a spring axis (36a), and a support element (54) for fixing the motor (18) in the centrifuge via the bearing unit (30), wherein the spring axes (36a) of the damping elements (36) are placed at an acute angle to the rotational axis Y of the motor (18).

There is provided a centrifuge including a rotor including a weight movement mechanism that supports a solid adjustment weight to be movable along a radial direction on an opposite side in the radial direction from an end portion of the rotor by which a specimen to be centrifuged is held; and a center-of-gravity adjustment unit disposed at a position away from the rotor to be connectable to the rotor, and including a weight drive mechanism connected to the weight movement mechanism to move the adjustment weight on the rotor. The center-of-gravity adjustment unit calculates a movement amount or a movement position of the adjustment weight according to an input weight of a container storing the specimen, and moves the adjustment weight.

A self-balancing mechanism for a centrifuge for the papermaking industry includes: a flange; a torus coupled to the flange; and a set of free bodies disposed within the torus. In response to a slurry being introduced into a perforated cylinder of a rotor of the centrifuge, each free body of the set of free bodies is configured to move within the torus in response to a rotational unbalance of the rotor to which the self-balancing mechanism is coupled caused by introducing the slurry.
