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.
