ABSTRACT:
A reagent pump assembly for metering precise volumes of fluids, such as reagent, for an analytical instrument, such as a clinical hematology or flow cytometer instrument. The assembly includes a multilayer block having a plurality of diaphragm pumps interposed between two of the layers, controlled by application of one of vacuum or pressure, in sequence, to fill the reservoirs and expel the contents of the pump. One-way check valves are used to control the fluid flow from the reservoirs of fluids to the fluid outlet ports. The fluid outlet ports may be directly coupled to fluid inlet ports of a compatible unified flow circuit, which contains reaction chambers and a plurality of sample aliquots. Thus, the reagent pump assembly can be used to combine and mix a sample aliquots with a precise amount of reagent in a reaction chamber, preparatory for analyzing the reaction mixture.
