A vertically oriented flexible centrifuge tube is placed in a rotor cavity or other enclosure, and the open end sealed with a tapered plug. The plug is formed with a peripheral groove in the tapered portion. A retaining disc, secured to the open end of the enclosure, wedges the plug into the open end of the flexible tube. The mouth of the enclosure is flared to accommodate the plug's taper. When the tube is centrifuged, the wall of the tube cold flows into the groove forming a locking seam such that the tube and plug are mechanically locked together and maintain an effective pressure seal.
