CENTRIFUGE ROTOR WITH LIQUID SUPPORTED SWINGING TUBES

摘要

A centrifuge rotor having an internal chamber in which are mounted a plurality of swinging centrifuge tubes containing fluid samples. Located within the rotor chamber is a liquid support medium which minimizes the amount of stress experienced on the centrifuge tube and at the pivotal junction of the tube with the rotor. The unique arrangement of having the buoyant force of a liquid within the rotor provides support to the tubes when the tubes have pivoted to their position during operational speed. The liquid support is designed to reorient in response to centrifugation in order to automatically provide the buoyant force to the tube during centrifugation and thereby reduce or greatly minimize the strength necessary in the mechanical design and construction of the support elements for the swinging tubes or containers.
