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.
