ABSTRACT:
A dual seal arrangement for use in a rotor to ensure the retention of the fluid sample within the test tube cavity during high speed centrifugation in an ultracentrifuge. The dual seal arrangement provides not only a seal on the test tube within the rotor tube cavity, but also a seal on the rotor tube cavity itself. One seal provides a capping arrangement on the test tube to securely seal the fluid sample within the test tube which rests within the rotor tube cavity. A secondary seal is positioned within the rotor tube cavity above the capping seal to provide a complete seal of the rotor tube cavity above the test tube.
