The invention relates to a multi-chamber container and to a method for producing medical liquids, which are composed of concentrates that make a contribution to the electrical conductivity of the solution and which are further produced from concentrates that make no contribution to the electrical conductivity of the solution. The multi-chamber container according to the invention is characterised by a distribution of the constituents of the solution into several chambers that are designed in such a manner that, by breaking down the first chamber boundary of one constituent of the solution that makes a contribution to the electrical conductivity of the medical solution, a further chamber boundary of a further constituent of the solution that makes no contribution to the electrical conductivity of the solution is broken down during the dissolution.
