Tube for use in a pelleting centrifuge rotor

摘要

A tube for use in a pelleting centrifuge rotor is characterized in first aspect by a first, acute, corner and a second, obtuse, corner defined in the lowermost pelleting region thereof. The corner defined by the acute angle lies a greater axial distance from the mouth of the tube than the corner defined by the obtuse angle. In a second aspect the tube the interior of the tube has a constricted region with a guide adjacent thereto. The guide channel is sized to accept a supernatant removal implement.
