Abstract
A method and apparatus for achieving substantially simultaneous dilution or mixing and dispensing is disclosed wherein the diluent or carrier is supplied by a syringe including a relatively large diluent reservoir and a pipette including a replaceable tip for containing a specimen or concentrate, the syringe including a nozzle or tube extending into the interior of the replaceable tip to produce a jet of diluent directed toward an outlet opening formed by the replaceable tip, the specimen being intermixed with the diluent jet for substantially simultaneous dispensation. In a preferred embodiment of the syringe which may be employed by itself or within the above noted diluting dispenser, a replaceable cartridge provides a relatively large volume of the diluent or other material for delivery by the syringe.
