Abstract
A multi-compartment centrifuge rotor having a sealing element which automatically controls in response to the centrifugation operation the fluid communication between the separate 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, centrifugal forces exerted directly on the sealing member cause it to move and release the seal between the respective chambers to allow fluid communication between the chambers. As the rotor returns to a stationary position and the centrifugal forces induced on the sealing member subside, the sealing element automatically re-establishes the seal between the respective chambers.
