Micro-centrifuge rotor for h igh-speed applications

A rotor for a centrifuge, the rotor defining an axis of rotation and the rotor comprising:

• a rotor body extending circumferentially about the axis of rotation, wherein the rotor body comprises:
• a first end and a second end;
• an annular portion extending circumferentially about the axis of rotation, wherein the annular portion defines a plurality of apertures;
• and
• an extension extending circumferentially about the rotation of axis, wherein the extension extends away from the annular portion and terminates at a bottom end;
• and
• a plate extending circumferentially about the axis of rotation and terminating at a distal end and at a proximal end, wherein the distal end of the plate contacts the first end of the rotor body and the proximal end of the plate contacts the second end of the rotor body.
