Abstract
An adapter preferably of ultra high molecular weight polyethylene is provided for use with a conical centrifuge tube in an ultracentrifuge swinging bucket rotor hole and is designed to allow the easy removal of the adapter and tube after centrifugation. At the top of the adapter is an integral annular rim with an outside diameter equal to that of a cylindrical upper portion of the centrifuge tube and with a minimal clearance to the diameter of the rotor hole. Immediately below the annular rim and adapter diameter reduces to a lesser diameter and continues until intersection with a hemispherical bottom region. The internal configuration of the adapter has a tapered conical section ending in a reduced diameter hemisphere, the internal taper and hemisphere of the adapter exactly matching the exterior of supported conical portion and hemispherical termination end of the sample tube.
