Abstract:
A disposable disruptor agitator tool for processing a sample comprising:a stator and a rotor defining an axis, said rotor disposed for rotation within said stator, one of the ends of said rotor having four vanes adapted to couple to a drive means for rotating said rotor, said rotor having a screw thread on an outer portion thereof, said screw thread extending along a substantial portion of said rotor and configured to provide a reverse pumping action to the sample, another end of said rotor having two opposed blades for shearing the sample; said stator being generally tubular in shape, one end of said stator having L-shaped reliefs adapted to receive a mating adapter, said stator having circular pressure relief openings therein, another end of said stator having axially elongated openings extending from said another end for cooperating with said rotor blades to permit the sample to be expelled from the stator while shearing solid particles of the sample.
