Abstract:
A centrifuge chamber for a cell separator having a separation channel comprising:at least one channel section bordered by an inner side wall and an outer side wall, the inner side wall being radially closer than the outer side wall to an axis of rotation of the centrifuge chamber;an inlet for introducing a cell suspension in the separation channel; andat least one outlet for withdrawing a fraction of the cell suspension, wherein a path line defining a locus of midpoints between the inner and outer side walls describes the at least one channel section, the path line having a spiral shape extending from a radially outer end of the separation channel to a radially inner end of the separation channel, having a progressively varying slope defined for each point of the path line as an angle between a first tangent to a circle about the axis of rotation intersecting the point, and a second tangent to the spiral at the point.
