A centrifuge (70) is provided with a cup (80) configured to house a blood bag system (10a) and centrifugally separates blood in the blood bag system (10a) by rotating the cup (80). The cup (80) has a segment holding section (86) capable of holding a plurality of segment tubes (44a), aligned in a parallel state by being folded at a sealing portion (44b) of an outlet-side tube (44), along a direction in which a centrifugal force acts during centrifugal processing or a direction inclined with respect to the direction in which the centrifugal force acts.

A tube rack of a centrifugal separator, in which a bottom rubber portion can be readily mounted and readily replaced, and yet such bottom rubber portion cannot be easily separated. The tube rack includes a holder (14) including a plurality of tube holes (12) each configured to accommodate a tube that is used for a sample and each includes an opening at one end portion of the holder serving as a tube insertion side, and an opening at a bottom portion of the holder that is at the other end. The tube rack includes a bottom rubber portion (15) including a plurality of bottom rubber members (25) each fits in the tube hole (12), and including connecting pieces (24). The tube rack includes a base (13) formed in a cylindrical shape having a bottom configured to accommodate and detachably hold the holder (14) and the bottom rubber portion (15), and to be inserted into a bucket of the centrifugal separator.

A rotor assembly includes a rotor plate to rotate around a first axis, a bucket attached to the rotor plate and to rotate around a second axis, and a stop plate to rotate around the first axis between an open position and a closed position. When in the closed position, the stop plate engages the bucket to fix an angular position of the bucket relative to a plane of rotation of the rotor assembly. The rotor assembly further includes a housing for a sensor array component, the housing disposed in the bucket and including a solution inlet, a solution outlet, a transfer basin, a solution retainer disposed between the solution outlet and the transfer basin, and a collection reservoir in fluid communication with the transfer basin. The solution inlet and the solution outlet to engage ports of a flow cell of a sensor array.

An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the as collected condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.

A centrifuge insert is provided which is not only suited for one type of sample container or sample carrier but for at least two geometrically different elements from the group consisting of sample container and sample carrier. This achieves that the same centrifuge insert can be used for different sample containers or sample carriers. This provides space savings, in particular in the lab. Furthermore acquisition cost is reduced, and handling is accelerated by reducing manual complexity which increases lab through put.

A centrifuge includes a swing rotor. Rotor arms of the swing rotor have recesses into which hangers of the swing rotor at least partially swing in a swung-out state. As a result, the centrifuge container and thus also the centrifuges are more compact, because the swinging-out requires less space. An inertial mass of the swing rotor is reduced due to the recesses provided therein, whereby energy consumption, primarily when starting the centrifuge, is significantly reduced.

A device provides selective modes of vibrational oscillations and centrifugal rotations for preparing analysis samples. The device includes a base, an elastic connection body, a group of a synchronous unidirectional bearing inner ring and a synchronous unidirectional bearing outer ring, a group of an eccentric unidirectional bearing inner ring and an eccentric unidirectional bearing outer ring, and a synchronous fixed ring and a motor on the base. The eccentric unidirectional bearing outer ring is connected to a sample plate for holding the analysis samples.

The present invention relates to a centrifuge container for a centrifuge rotor, with a base body comprising an opening, a vessel bottom and a longitudinal axis, the opening and the vessel bottom being situated opposite each other and the base body extending with its overall length between the opening and the vessel bottom, and the centrifuge container comprising, along the overall length of the base body, a first section extending from the opening and a second section extending to the vessel bottom, the centrifuge container comprising structure non-detachably connected to the container for reducing the flow resistance, the structure being provided exclusively in the region of the second section.

A rotor assembly includes a rotor plate to rotate around a first axis; a bucket rotatably attached to the rotor plate and to rotate around a second axis; and a stop plate to rotate around the first axis relative to the rotor plate between an open position and a closed position, when in the closed position, the stop plate is to engage the bucket to fix an angular position of the bucket relative to a plane of rotation of the rotor assembly.

A sample processing arrangement for processing a fluidic sample, the sample processing arrangement including a sample holder for accommodating the fluidic sample, an apparatus having a rotor mechanism and being configured for selectively operating the sample holder in an orbital motion mode for sample mixing, particularly for shaking, or in a rotary motion mode for sample separation, particularly for centrifuging, a mounting platform having a central portion on which the apparatus and the sample holder are mounted and having a surrounding portion circumferentially surrounding the central portion, and a plurality of module accommodation positions circumferentially distributed in the surrounding portion to surround the rotor mechanism and the sample holder, wherein each of the module accommodation positions is configured for detachably accommodating a selectable one of a plurality of sample processing modules, each being configured for fulfilling an assigned sample processing task, by accommodating the respective sample processing module in the respective one of the module accommodation positions.
