Abstract
A multi-lumen tube arrangement for use in a centrifuge free of a sliding seal, the tube arrangement having at least two individual tubes which are rotated around one another around their longitudinal and/or their parallel axes. The rotation of the tubes takes place in this connection in opposite directions starting from a support position disposed approximately centrally in order to compensate the torques applied to the tube arrangement. A method for manufacturing such a tube arrangement is also decribed.
