The invention relates to a device for producing a predeterminable volume of components of solution mixtures with a metering device for the solution mixture, a separator that is downstream of said metering device and is intended to separate out undesired components contained in the solution mixture, and a vacuum unit for evaporating the solution mixture, which is precleaned in the separator, to the predetermined volume, whereby a conveyor having a predeterminable rate of flow is upstream of the separator and a device for preventing the flow rate of the conveyor from being affected by the vacuum present in the vacuum unit is upstream of the vacuum unit.
