Adapter for holding a pair of centrifuge tubes.

摘要

An adapter for a centrifuge tube comprises two adapter segments, each of which has an exterior surface and a mating surface thereon. Each segment has a pair of indentations in the mating surface. When the segments are joined along their mating surfaces the indentations cooperate to define a pair of recesses therein. Each recess so defined is configured to surround totally a centrifuge tube disposed therein. Each recess has an axis extending therethrough, with the axes of the recesses being collinear. The collinear axes of the recesses are aligned parallel to the axis of rotation of the rotor, and preferably also align collinearly with the axis of the rotor cavity in which the adapter is disposed. Each adapter segment is fabricated of a material that has sufficient strength to withstand the vertical forces created by the pressure of a liquid under centrifugation. At least one of the adapter segments has an effective weight sufficient to balance forces created by the pressure of a liquid carried in the tubes under centrifugation that act transversely to the central axis. <IMAGE>
