Abstract
A method for making a thin wall centrifuge tube using an injection blow molded process to achieve not only uniform thickness of the tube, but also uniform or homogeneous material properties throughout the tube structure. The unique application of this process includes the making of a preform mold which retains its molten stage on a transferrable core pin that is received at a second stage, where the final configuration mold is placed around the core pin. The blow molding stage operates in conjunction with the molten preform to create the high strength centrifuge tube with uniform material properties.
