Abstract
An arrangement for withdrawing supernatant from a deposition surface is provided for use with a cytocentrifuge chamber block. The block receives an absorbent plug in a recess provided therein. The plug is restrained from movement past a predetermined point until a predetermined insertion force corresponding to a predetermined rotor speed is imposed on the plug. At that time a resilient restraining arrangement deflects to permit the plug to advance with respect to the block. The restraining arrangement preferably takes the form of tines resiliently mounted to the plug.
