A method and apparatus for preparing a medical solution is simplified compared to the prior art. The present invention relates to a method for preparing a medical solution from at least one first liquid component and at least one second liquid component, wherein the first component and the second component are each The mixed solution is obtained by being transported by the transport means, the transport means is operated so that the concentration of the first and second components is modulated, and the conductivity of the mixed solution or the parameter correlating with the conductivity is measured. Concentration modulation, measured at points, is performed in the desired state such that no modulation of the measured conductivity or parameter correlating with the conductivity occurs or a specific desired modulation occurs. The invention further relates to an apparatus for preparing a medical solution and a blood treatment device comprising such an apparatus.
