ABSTRACT:
A vertically oriented centrifuge tube is placed in a rotor cavity and the open end sealed with a tapered plug. A resilient O-ring is placed in an annular groove formed in the top of the tapered plug and a retaining disc, secured to the open end of the cavity, wedges the plug into the open end of the centrifuge tube. The O-ring, being resilient, maintains an axial force which aids in retaining the tapered plug properly seated within the open end of the centrifuge tube, even during and following the stresses of centrifugation.
