A multichamber container and a method of preparing medical fluids having concentrates which make a contribution toward the electrical conductivity of the solution and are additionally prepared from concentrates which do not make a contribution toward the electrical conductivity of the solution. The multichamber container is configured by dividing solution components into multiple chambers, so that following the dissolving due to breaking open of the first chamber border of a solution component, which makes a contribution toward the electrical conductivity of the medicinal solution, another chamber border of another solution component which does not make any contribution toward the electrical conductivity of the solution is broken open.
