Disclosed is a diluting method and apparatus which pumps a metered volume of a diluent into a conduit system, one portion of which includes a metered capillary tube bypass, into which is separately drawn concentrate. Once the system portions are filled with diluent and concentrate, a metered pumping of diluent forces diluent through the capillary bypass and forces the concentrate to mix with the diluent. The volume of mixed dilution thereby forced from the system equals the volume of the metered diluent. The structural arrangement includes valves which coact to obviate the need for between dilution rinsing of the system.
