The invention relates to an apparatus for hemodialysis comprising a mixing means which prepares dialysis solution for a dialyzer by mixing concentrate with prepared water. The apparatus comprises a protective system which is independent of the mixing system and which is based on monitoring the conductivity of the dialysis solution. For protection against confusion of the concentrate containers to be connected, in the concentrate intake conduits conductivity measuring cells are additionally provided and the output signals thereof are compared with the desired values of the conductivity of the concentrates of the concentrate containers to be connected. In advantageous manner said conductivity cells are integrated into the concentrate intake conduits in such a way that they serve simultaneously as level sensors for the concentrate in the containers.
