Abstract: A centrifuge including flexible tubes in fluid communication with containers for a sample being centrifuged and having portions extending into the containers. The containers are held in a ring which is detachably secured to the centrifuge rotor. The device includes means for withdrawing those portions of the tubes which extend into each container inwardly towards the center of the centrifuge a distance sufficient to permit the ring holding the containers to be freely raised off the centrifuge rotor. In a preferred embodiment, the tubes are in liquid communication with a chamber for holding a liquid and motion of the chamber either axially or rotatably or both with respect to the rotor withdraws the conduits from the liquid containers.

Abstract: A rotation-sensitive pumping device for pumping liquid from one part of a centrifuge to another during rotation thereof comprises a diaphragm mounted on the centrifuge rotor and moveable from one position to another as a function of rotor speed to pump the liquid. The diaphragm is disposed at an angle between two rotating chambers of the centrifuge and, at a given angular velocity of the rotor, the diaphragm is moved by centrifugal force from one position to the other to pump the liquid from one chamber to the other. The diaphragm may include two flexible diaphragms separated by a cavity filled with a fluid. A partition wall may be located in the space between the diaphragms forming cavities between the partition wall and each diaphragm. An aperture is provided in the partition wall for the passage of fluid between the two cavities on motion of the diaphragms.

Abstract: A centrifuge comprises a rotating chamber containing a compressible container for the liquid to be centrifuged. The centrifuge also includes means to compress the container to transfer liquid from the container during centrifugation. The compressing means is also capable of compressing one or more further compressible containers to transfer liquid therefrom to the first-mentioned compressible container. The compressing means is preferably a diaphragm member which is urged by centrifugal force against a compressible container. In one application, the container is filled with blood to be centrifuged and, after the serum is separated, a valve is opened permitting the diaphragm to compress the container to transfer the serum to a further container. The valve is then closed and speed reduced until the diaphragm returns to its rest position causing compression of a still further container provided with wash water. A valve is then opened to permit transfer of some or all of the wash water into the first-mentioned container and the device may then be braked to cause the water to mix with the blood cells therein. The washed blood cells are then centrifuged and the water transferred to the water container or yet a still further container by the actuation of an appropriate valve similarly as in the case of transferring the serum. The washing operation is repeated if desired until all of the wash water has been utilized.
