1. An apparatus for manipulating particles, the apparatus comprising:
a rotor rotatable at a speed about an axis, the rotor having an outer periphery and front and rear opposite sides;
at least one chamber mounted on the rotor, each chamber having an inlet and an opposed outlet;
an umbilical assembly rotatable about the axis, the umbilical assembly comprising:
a curvilinear guide connecting to the rear side of the rotor;
a flexible conduit residing in the guide; and
first and second elongate passageways for each chamber extending through the conduit, wherein the first passageway is in fluid communication with the inlet of a respective chamber and the second passageway is in fluid communication with the outlet of the respective chamber; and
a drive mechanism configured to rotate the umbilical assembly at about one-half the speed of the rotor;
wherein each chamber comprises a substantially conical body portion and a flange extending about at least a portion of a perimeter of the conical body portion, the flange defining a plane and the conical body portion extending outwardly from the plane, the flange including an inlet fluid path that is external to the conical body portion and extends around at least a portion of the perimeter of the conical body portion to the chamber inlet and an outlet fluid path that extends from the chamber outlet, and wherein the first elongate passageway is in fluid communication with the flange inlet fluid path and the second elongate passageway is in fluid communication with the flange outlet fluid path,
wherein each chamber is configured to allow fluid flow therethrough while the rotor and the chamber rotate about the axis such that a force of fluid flowing from the inlet to the outlet opposes a centrifugal force created by the rotation of the rotor and the chamber,
wherein a fluid flow path from the inlet to the outlet is perpendicular to the axis.
