Abstract

A method of preparing a solution is described, in particular a dialysis or infusion solution, and a storage system for preparing such a solution. An acid-reacting component comprising a solid acid and/or a solid salt which is water-soluble and is not hygroscopic, is dissolved in water in a first container and mixed with an alkaline-reacting bicarbonate solution in a second container. The quantity ratios are selected so that the acid and/or salt content does not exceed 6 mmol per liter of finished solution and the bicarbonate content does not exceed 40 mmol per liter of finished solution.
