摘要:
The invention relates to a centrifuge (1) for high-speed centrifuging, comprising: a shaft (2), mounted for continuous rotation about its axis, the shaft having a working section (4) having a loading end and an unloading end; an acceleration member (3) mounted adjacent to the loading end for rotation with respect to the shaft and; a deceleration member (5) mounted adjacent to the unloading end for rotation with respect to the shaft; auxiliary drive arrangement (10) for accelerating the acceleration member and the deceleration member to the shaft speed; carriages (7) for supporting specimens for centrifugation. The carriages (7) are slideably mounted for traversing from the acceleration member (3) to the working section (4) and from the working section to the deceleration member (5). A carriage may be accelerated on the acceleration member and then transferred to the working section for a period sufficient to perform centrifuging and then transferred from the working section to the deceleration member.
摘要:
In one aspect, a disposable centrifuge includes a container including an interior compartment for receiving the liquid and solids. The container is capable of rotating to urge the solids toward the periphery of the interior compartment. A fixed extraction conduit may be provided for extracting at least a portion of the solids from adjacent the periphery of the interior compartment of the container. A motive device may also be provided for forming a non-contact coupling with the container, which may rotate and/or levitate the container. A relatively low, continuous flow rate (about 250 ml/min to about 500 ml/min) may also be utilized. Related methods are also disclosed.

L'invention a pour objet une centrifugeuse comprenant : un arbre d'entraînement, un rotor destiné à être monté de façon amovible sur ledit arbre d'entraînement dans une position de montage pour laquelle ledit arbre d'entraînement et ledit rotor sont accouplés en rotation, un dispositif assurant un blocage axial du rotor sur ledit arbre d'entraînement, comprenant au moins un élément mâle porté par ledit rotor, sollicité élastiquement et susceptible d'occuper une position de coopération avec un élément femelle présenté par ledit arbre d'entraînement, caractérisée en ce que ledit ou lesdits éléments mâles sont couplés à des moyens d'indication visuelle et/ou tactile procurant une indication visuelle et/ou tactile de ladite position de coopération dudit ou desdits éléments mâles avec ledit élément femelle.
摘要:
A centrifugal concentrator in which there is a common shaft for the drive motor and concentrator bowl. The cost of bearing assemblies is thereby minimized. The bowl is driven and suspended from above to keep the motor out of the slurry area and maximize the simplicity of the design. A fluidizing fluid is delivered through the common shaft.
摘要:
An apparatus and method of forming a solid-fibrin web. The apparatus includes a centrifuge (600) having a housing (604), and actuator (648), a wheel (660), and a flange (664). The housing includes a recessed area (616) and a base (608) supportable on a surface. The wheel is coupled to the actuator and extends into the recessed area and is adapted to contact a first end of a container (620). The flange extends into the recessed area opposite the wheel and defines an adjustable distance between the wheel and the flange. The flange is adapted to contact a second end of the container and the actuator is operable to rotate the container. The container is oriented substantially parallel with respect to the base.
摘要:
A microfluidic centrifuge is provided that includes a microfluidic disc having a pair of through holes that include a first through hole and a second through hole, where the pair of through holes are disposed symmetric and proximal to a central axis of the microfluidics disc, where the microfluidics disc includes a sealable input port and a sealable output port, where the sealable input port and the sealable output port are connected by a microfluidics channel, and a pair of tethers disposed through the pair of through holes that are disposed to twist about each other for unwinding, where the tether unwinding is disposed to interact with the through holes, where the microfluidics disc rotates about the central axis.
