Centrifuge drive apparatus comprising
- a support including a plurality of resilient mounting members that are spaced around a rotation axis and are intersected by a mounting plane that is perpendicular to said rotation axis,
- a centrifuge bowl and drive motor assembly including a rotatable centrifuge bowl and a drive motor supported by said mounting members, said drive motor being operable to rotatably drive said bowl about a rotation axis, said rotating bowl including a recess for receiving a channel and an opening permitting passage therethrough for inflow and outflow tubes,
- said centrifuge bowl and drive motor assembly having a combined center of gravity in the vicinity of said mounting plane to reduce vibration, and
- a disposable tube set including a separation channel received in and carried by said bowl said inflow and outflow tubes having one end attached to said channel, passing through said opening and the another end fixed to said bowl rotating means, and a midsection that is rotated by said assembly at one-half of the rotation of said bowl.
