1. A rotor for a centrifuge used to separate a mixture of components in a fluid having different densities, the rotor comprising:

  • a hollow curved housing that has an inner wall and an outer wall, a top, a bottom and a first end and a second end wherein the inner wall is radially closer to an axis of rotation as compared to the outer wall;

    the hollow curved housing being formed of a curved first rotor element that terminates at the first end of the curved housing and a curved second rotor element that terminates at the second end of the curved housing wherein the curved housing between the curved first rotor element and the curved second rotor element includes a junction that creates a change in an inner and outer radius of the first rotor element as compared to an inner and outer radius of the second rotor element;

    an input port positioned on the inner wall of the first rotor element between an output port of the first end and an output port positioned on the inner wall of the junction;

    an output port positioned on the inner wall of the first rotor element between the output port at the first end and the input port;

    an output port in the second end; and

    the hollow curved housing from the first end to the second end forming an about 150-360 degree curve about the axis of rotation;

    wherein the first end is a distance d4 from the axis of rotation, the second end is a distance d3 from the axis of rotation and the junction is a distance dr from the axis of rotation with d4>

    dr>

    d3.
