<p>A centrifuge rotor having a sealing element which automatically controls in response to the centrifugation operation the fluid communication between separate fluid mixture chambers within the rotor. The sealing element is situated within the rotor above an annular and an inner chamber used for containing a fluid mixture. When the rotor is assembled and stationary, the sealing element establishes a seal between the respective chambers. During the rotation of the rotor in a centrifuge, the centrifugally induced pressure exerted by the fluid mixture moves the sealing element, releasing the seal between the respective chambers and allowing fluid communication between the chambers. As the rotor returns to a stationary position and the centrifugally induced pressure of the fluid mixture subsides, the sealing element automatically re-establishes the seal between the respective chambers.</p> |
