ABSTRACT:
A long, thin annular belt-like channel can be used in sedimentation field flow fractionation. A rotating seal is required to couple fluids to the channel inlet and from the channel outlet. A flexible shaft is used to drive the rotating seal and thereby decouple rotor vibrations, which cause can leakage, from the rotating seal.
