Preparation device and method for preparing a cell suspension for an analytical method

A preparation system for preparing a cell suspension, comprising a carrier at which a reactor housing and a magnet system are accommodated, wherein a reaction channel for receiving the cell suspension is formed in the reactor housing, said reaction channel extending between an inlet opening arranged centrally on an upper side of the reactor housing and an outlet opening arranged on an outer perimeter of the reactor housing and wherein the reaction channel is bounded by at least one channel wall, and wherein the magnet system is disposed on the carrier so as to be movable between a first functional position, in which a pole face of the magnet system bears against the at least one channel wall of the reaction channel and a second functional position in which the pole face of the magnet system is located at a predetermined distance with respect to the at least one channel wall, and wherein the preparation system further comprises a reactor housing drive to initiate a rotational movement on the reactor housing about an axis of rotation, and

• wherein the reactor housing comprises recesses formed in the reactor housing by the at least one channel wall on an upper side of the reactor housing adjacent to the reaction channel and/or on a lower side of the reactor housing adjacent to the reaction channel, said recesses being engageable with the magnet system, and
• wherein the magnet system comprises, a surface profiling facing the reactor housing with depressions and elevations, the elevations enabling an engagement of the magnet system in the recesses of the reactor housing.
