Abstract
A chuck device comprises clamp elements having, at one end, an underlying tooth and a conical surface conjugated with the surface of a centrifugation cell. The clamp elements are uniformly distributed on the circumference of a plate including a surface upon which the bottom of the cell rests. The clamp elements are pivoted on the plate so as to be rotatable in radial planes, and can be locked in the closed position.
