ABSTRACT:
A means of sealing a centrifuge tube which makes use of the hydrostatic pressure of the sample solution contained in the tube to perfect a tight seal during centrifugation. The filler stem is plugged with a plug which is supported in the rotor cavity. The hydrostatic pressure forces the filler stem against the plug to effect a seal with a sealing force which is dependent on the hydrostatic pressure which is in turn dependent on the centrifugal force on the sample solution.
