A centrifuge(200) includes a disk and centrifuge exhaustion disk. A plurality of second pins are combined with the external surface of the centrifuge. A casing(300) with an insertion hole(320) accommodates inner case and centrifuge inside. A bottom plate(340) is connected to the lower part of the casing and linked to the lower part of the inner case. A plurality of beads(400) move in the space of inner case, centrifuge, and casing. A rotation shaft(500) is inserted into the insertion hole. A sealing member(600) seals the gap between the insertion hole and rotation shaft.
