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 is configured to provide integrated separation of blood components such that the separated products remain spinning within the centrifuge during the separation process. The centrifuge includes a disposable configured to separate the blood components such that the separated products remain within the disposable while the centrifuge is spinning; an integrated sensor system capable of determining a composition of the separated products within the disposable while the centrifuge is spinning; a chamber having a non-circular section that is configured to be deliberately un-balanced when the centrifuge chamber is empty; and the disposable includes valves that rotate with the centrifuge chamber.

Embodiments of a portable and compact centrifugal system are described, comprising a centrifuge body comprising a motor; and 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 rotor with a counterweight and wherein the tube retainer and the counterweight are 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, lid-closure sensor, motor, and automatic timer; free of both user controls and user displays.

A vibration isolation holding device includes a body portion and an abutment member. The abutment member is arranged between the body portion and a bearing housing, and has an abutment surface abutting on the bearing housing, when a cartridge is held. A biasing member is disposed between the abutment member and the body portion. An interval between the body portion and the abutment member is regulated by a first regulating portion to be shorter than a natural length of the biasing member.

The present invention relates to a system for conducting the identification and quantification of micro-organisms, e.g., bacteria in biological samples. More particularly, the invention relates to a system comprising a cooling, heating and fan arrangement for maintaining a predetermined optimum temperature of the samples during testing; a visual, circumferential and axial alignment system for aligning the samples within the carousel; a transfer system for transferring the samples from the carousel to the centrifuge; a balancing system of minimizing the rotational vibrations of the centrifuge; a safety system and anti-tipping design for the sample containing system; liquid dispensing arms for dispensing the buffered saline solution; and discharge ports for discharging and disposing of the liquid removed from the samples to a location external of the system.

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.
