A centrifugating device for biological liquids, e.g. blood, in which a rotatable container carries a specially shaped seal that surrounds and bears on a fixed assembly with a minimum area of interface between the fixed and rotating parts. This seal is disposed outside the path of the liquid to be treated. The fixed assembly, in turn, is releasably carried by a bracket, the bracket being selectively longitudinally extensible as well as selectively adjustably swingable about a vertical axis of oscillation eccentric to the centrifuge, thereby to permit exact positioning of the fixed assembly coaxially of the rotatable container. The parts are so simple and inexpensive in construction that at least some of them can be used once and thrown away. Moreover, the fixed assembly is easily insertable in sealed relationship in any of a variety of containers, by the simplest of manual assembly and disassembly operations.
A centrifugating device for biological liquids, comprising a fixed assembly for the inflow and outflow of the liquid to be centrifuged, a container rotatable about said fixed assembly coaxially with said fixed assembly, and an annular seal between said fixed assembly and container, said seal rotating with said container and having substantially line contact with said fixed assembly, said seal being at the top of the container and being easily insertable in and removable from said container, said seal being outside the path of the liquid to be centrifuged, the portions of said fixed assembly below said seal being of smaller diameter than the portions of said container that they pass upon assembly and disassembly of said fixed assembly and said container, whereby said assembly and disassembly are easily effected by the mere fricitional engagement and disengagement of the seal with and from the container.
