ABSTRACT:
The invention provides a device for locking the base of a blood centrifugation cell on a rotatable generally disc shaped chuck plate. The chuck plate encloses a plurality of elastic locators which extend radially a slight distance from the periphery of the plate. The plate further encloses a plurality of locking means which are biased to remain within the dimensions of the plate at rest and which are radially extendable by centrifugal force to extend beyond the periphery of the plate. An annular locking ring engages the base of the cell and extends around the periphery of the chuck plate. The locking ring has a plurality of internal recesses for initially receiving the elastic locators, and the locking means during centrifugation to secure the cell to the chuck plate.
