1. A sample processing device comprising:
- a programmable fluid handling system;
a cartridge receiving location accessible by the programmable fluid handling system;
at least one optical detector positioned at a location accessible by the programmable fluid handling system;
a centrifuge positioned at a location accessible by the programmable fluid handling system, wherein the centrifuge comprises;
a motor assembly comprising a rotor configured to rotate about a stator about an axis of rotation, wherein the motor assembly has a height that is oriented along the direction of the axis of rotation, wherein along said height said stator is circumscribed by said rotor; and
a base affixed to the rotor, wherein the base rotates about the stator, wherein the base comprises at least one bucket that is characterized in that (a) the bucket comprises a cavity to receive a sample vessel and (b) the bucket is configured to pivot about a pivot axis to move the cavity from a first orientation when the base is at rest to a second orientation when the base is rotating, wherein the bucket at a fully extended orientation does not extend beyond a circumferential perimeter of the base, and wherein the centrifuge is capable of achieving a rotational speed of at least about 1,000 RPM and wherein an entire bottom surface of the centrifuge is about 200 cm2 or less.
