A rotor for use in a centrifuge, and adapters for coupling one or more processing containers to the rotor. The rotor includes a rotor body having a plurality of receptacles each configured to receive an adapter. Each adapter includes an outer surface configured to interface with one of the receptacles, and one or more cavities each configured to accept a processing container. The rotor may also include a rotor liner positioned between the adapters and the rotor body. The rotor liner engages the receptacles of the rotor body, and provides a plurality of receptacles that receive the adapters, thereby providing an interface between the adapters and the receptacles of the rotor body.

A centrifuge rotor for sample vessels includes a seal between a lower part and a cover. The seal comprises a gasket, which is arranged in a first groove. The first groove is arranged on one of the elements constituted by the cover and the lower part. The first groove, in relation to the axis of rotation of the centrifuge rotor, is open axially toward the other of the elements constituted by the cover and the lower part.

The present invention addresses the problem of providing a centrifugal smearing device and a sealed rotating container in which liquid components do not leak to an outside of the sealed rotating container. To solve this problem, in a centrifugal smearing device (30) including a sealed rotating container (34) that houses a chamber (10) with a slide glass removably attached for holding the liquid sample to smear cells in the liquid sample with a centrifugal force onto the slide glass, and a base (31) housing the sealed rotating container (34) and including rotational driving means (32) for rotating the sealed rotating container (34), the sealed rotating container (34) includes a main body (40) capable of housing the chamber (10) and a lid (42) for closing an upper surface opening portion of the main body (40), and has a storage section (46) for storing liquid scattered from the chamber (10) during being centrifuged, formed on an inside face of the main body (40).

The invention relates to a laboratory centrifuge (1) with a coupling device (4) actuated by a centrifugal force. According to the invention an eccentric mass (22), especially a roller (23), is guided through a guideway (26) and preferably another guideway (27, 32) in such a way that the centrifugal force (46) of the eccentric mass (22) is deflected in such a way that a coupling force is generated which presses a coupling element (24) radially inwards against the outer surface of a drive shaft (3).

The invention relates to a centrifuge (10), having a drive shaft (12), a rotor (40) mounted on the drive shaft (12) so as to be detachable axially in a removal direction (66), a quick-action closure (54) integrated in the rotor (40) and the drive shaft (12), which closure can be used to secure the rotor (40) relative to the drive shaft (12) in a removal direction (66), an abutment (50, 52) in the drive shaft (12) which is engaged by a locking member (46) of the rotor (40), at least one blocking element (76), which—when activated—fixes the rotor (40) relative to the drive shaft (12) and which acts between the locking member (46) of the rotor (40) and the abutment (50, 52) of the drive shaft (12), which quick-action closure (54) includes a force-transmitting element (58, 72). The invention is characterized in that said blocking element (76) is actively connected to an actuating element (100, 100a) via the force-transmitting element (58, 72), that unlocking the quick-action closure (54) is effected by moving the actuating element (100, 100a), the force-transmitting element (58, 72) and the blocking element (76) relative to the locking member (46) in a direction in parallel to the drive shaft (12), and that during unlocking, the actuating element (100, 100a) is moved toward the drive shaft (12), and during locking, the force-transmitting element (58, 72) and the blocking element (76) on the one side and the locking member (46) on the other side are relatively moved toward each other.

A centrifuge rotor (10) includes a closure (32) between a lower part (12) of the centrifuge rotor (10) and a cover (14). The centrifuge rotor has been improved such that proper single-handed operation is made possible. In particular, the closure (32) can be closed and detached again using just one hand. The cover (14) includes a circular cut-out (20) for fastening the centrifuge rotor (10) in a centrifuge. The cover (14) is attached to the lower part (12) by levers having a concave shaping (66). The cover (14) and the levers cooperate to provide a visual indication whether the cover is properly closed.

A rotor assembly that includes a rotor body having a plurality of rotor wells. The rotor body includes an upstanding annular lip that defines an annular containment groove configured to capture and retain material leaked from a sample container received a rotor well during rotation of the rotor assembly. The rotor body also includes an annular containment lip that forms a continuous extension of the annular containment groove. The rotor assembly includes a lid selectively attachable to the open end of the rotor body that includes a first undercut channel configured to receive a portion of a first sealing gasket formed as an annular disk. The lid is supported above the upper surface of the rotor body by the annular containment lip such that the first sealing gasket is positioned between the lid and the annular containment lip to form a seal between the lid and the rotor body.

A valve bridge portion, in which four valves A to D are connected in a bridge shape, is interposed between sample lines to a rotor of a continuous centrifuge. A microcomputer is able to open and close the valves A to D independently and is capable of switching between top feed and bottom feed to the sample line. When sample supply is started, switching between the top feed and the bottom feed is performed multiple times, and in the middle of switching and sending a sample liquid, the microcomputer executes an operation of temporarily increasing a liquid pressure multiple times by temporarily closing an outlet valve (C or D) and then immediately opening the valve. As a result of repeating the operation of switching between the said sample feed directions and temporarily increasing the liquid pressure, air that accumulates inside the rotor can be effectively discharged.

A portable centrifuge comprising a base, which includes a rotational mechanism contained within. A sequester wheel having a plurality of concentric rings, forming at least one channel and a central container. The at least one channel comprising a second volume and the central container comprising a first volume. A first cover is disposed over the sequester wheel to create a seal. A second cover is disposed over the first cover and is rotatable to engage with the rotational mechanism to initiate rotation at a predetermined RPM. The whole blood, tissue or other cell types are separated into its constituent components and deposited into the at least one channel and the central container. Specific volumes of the constituent components, tissue and/or cell types may be calculated to match or substantially match the first and second volumes for predetermined volume control and ease of access.

A centrifuge including a rotor having at least one recess, at least one protrusion or a combination of the at least one recess or the at least one protrusion defining a concave arrangement, each of the at least one recess, the at least one protrusion or the combination of the at least one recess or the at least one protrusion adapted to receive a corresponding specimen container.
