ABSTRACT:
A secondary seal arrangement for use in a rotor to ensure the retention of the fluid sample within the test tube cavity of the rotor during high speed centrifugation in an ultracentrifuge. The secondary seal arrangement acts in cooperation with both a spacer member over the centrifuge tube and a sealing plug for the rotor cavity to provide a seal of the cavity over the test tube to reduce the possibility of escape of any fluid which may inadvertently exit the centrifuge tube itself. The secondary seal is positioned within the rotor tube cavity above the capping seal for the centrifuge tube to provide a closure of the rotor tube cavity above the centrifuge tube.
