Centrifuge assembly
First Claim
1. An assembly for a centrifuge, said assembly comprising;
- a rotatable tray having an axis of rotation, and comprising a plurality of orifices radially disposed from the axis, each said orifice being formed with a first contoured surface and a second contoured surface, each said orifice being sized to receive a sample tube, whereby the sample tube is disposed in the first contoured surface without rotation of the tray and the sample tube is disposed in the second contoured surface with rotation of the tray.

Abstract
A centrifuge system includes a drive motor mounted independently relative to a sample carrier to eliminate detrimental forces born by a motor drive shaft. The rotatable sample carrier or tray includes a rotating center operably connected to the drive motor. The drive motor cooperates with a resilient mounting system enabling self-centering, force and vibration compensation, and improving motor life. The rotatable sample tray and a sample tube holder have respective operably cooperative contoured surfaces enabling relative smooth pivoting motion in the sample tube holder during rotation, while minimizing sample vibration, and improving the desired sample separation while minimizing sample remixing. An air management system enables effective motor cooling and minimizes sample heating.

- 13. An assembly for a centrifuge, said assembly comprising a rotatable tray, holder means for holding at least one sample tube, and means for pivotably connecting said holder means to the rotatable tray, whereby with rotation of the tray the holder means pivots from a first position to a second position.

27. A sample tube assembly for a centrifuge comprising:
a body portion an upper portion and a lower portion, said body portion being disposed between the upper and lower portion, said body being formed with an interior surface for receiving a sample of flowable material for centrifugation and wherein said lower portion comprising an exterior bottom comprising an at least partially planar portion, whereby the sample tube assembly rests on the planar bottom so as to be free standing. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)

37. In combination:
-
a rotatable tray being formed with a contoured surface for receiving a sample tube and a sample tube holder having a contoured surface;
wherein the tray and sample tube contoured surfaces are cooperatively configured;
whereby with rotation of the tray, the sample tube contoured surface moves on the tray contoured surface from a first position to a second position. - View Dependent Claims (38, 39, 40)
