Abstract: A biological fluid sampling transfer device adapted to receive a multi-component blood sample is disclosed. After collecting the blood sample, the biological fluid sampling transfer device is able to separate a plasma portion from a cellular portion. After separation, the biological fluid sampling transfer device is able to transfer the plasma portion of the blood sample to a point-of-care testing device. The biological fluid sampling transfer device also provides a closed sampling and transfer system that reduces the exposure of a blood sample and provides fast mixing of a blood sample with a sample stabilizer. The biological fluid sampling transfer device is engageable with a blood testing device for closed transfer of a portion of the plasma portion from the biological fluid sampling transfer device to the blood testing device. The blood testing device is adapted to receive the plasma portion to analyze the blood sample and obtain test results.

Abstract: A device and a method for reducing wind resistance power of a large geotechnical centrifuge are provided. A semicircular tube cylindrical cooling device is provided between an internal side of a high-speed rotor system and a cylindrical shell. A serpentine top semicircular tube cooling plate is provided right above a hanging basket, and return helium gas inlet holes are provided at a center of the top semicircular tube cooling plate. A helium gas in a helium gas storage tank passes through helium gas outlets on the helium gas inlet pipes, and enters a centrifuge chamber from a bottom sealing plate. The helium gas is used to replace air in the centrifuge chamber to reduce the wind resistance power and corresponding energy consumption. No vacuuming is required, so sealing requirements are lower. Heat dissipation equipment is placed inside the centrifuge chamber, and a helium gas circulation wind duct is added.

Abstract: A separator for centrifugally processing includes a rotatable drum having at least two drum parts, which can be rotated relative to one another at a screw thread. A drum tool is designed to open and close the drum by rotating the drum parts screwed together by the screw thread. The drum tool includes a retaining element attachable to the one drum part, a driver element attachable to the other, relatively rotatable drum part, and at least one rotation device for the relative rotation between the retaining element and the driver element together with the drum parts. The retaining and driver elements each having two or more points of engagement for the rotation device. The points of engagement are symmetrically arranged in such a way that forces produced by the rotation device produce a torque for the relative rotation of the drum parts, but no resulting force acting on the screwed drum parts on one side is produced.

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: A separator insert for a separator includes a housing that is stationary during operation and is a container that is closed apart from multiple openings. These openings include a supply opening for an in-flowing suspension in a first axial boundary wall of the housing, two outlets for flowable phases of differing densities in an outer casing of the housing, and a recirculation inlet in a second axial boundary wall of the housing. A rotor within the housing can rotate about an axis of rotation and has a drum, which has multiple openings. A separator is arranged in the drum. At least two rotor units for magnetic bearing units are arranged at two axially spaced-apart points on the rotor with the drum, with which the rotor with the drum can be held in a suspended state, can be rotationally mounted and can be made to rotate within the housing during operation.
