Abstract
A centrifuge tube holder designed for use in a centrifuge rotor to hold a plurality of small volume tubes in such a manner that, when the centrifuge rotor is at rest, the tubes will be oriented at an inclined angle, but will assume essentially a horizontal orientation when the centrifuge rotor is operating. The holder provides improved collar support for the centrifuge tube during centrifugation and also provides for the inclusion of a tube pivot point in the plate to enhance the proper movement of the tube from its at-rest position to the correct support position during operational speeds of the centrifuge rotor.
