Abstract
A centrifuge tube and adaptor apparatus is provided which facilitates separation of biological materials and permits easy extraction of a fraction after centrifugation. The tube is a deformable tube with a wide upper chamber and a narrowed lower portion. The tube is supported within the centrifuge rotor or within another container within the centrifuge by a liquid support medium, which surrounds and supports the narrow portion of the tube, and thus prevents the tube from collapsing during high speed centrifugations.
