<p>A long, thin annular belt-like channel is designed for use in sedimentation field flow fractionation. This channel defined by inner and outer rings 104,102, which may be the rotor of a centrifuge, is designed to mainteain its thickness dimension constant by forming the radially inner wall with a radial thickness t such that the distorting effects of centrifugal force on the inner ring are substantially balanced by the centrifugal pressure of fluid in the flow channel.</p> |
