ABSTRACT A multifunctional liquid sampling, metering and transfer valve assembly and the analytical system employing same. The valve assembly is capable of performing the liquid handling functions required for metering, isolating, storing and delivering of precise volumes respectively of liquid sample, liquid diluent and liquid reactive reagent therewithin. The valve assembly comprises a pair of coaxially arranged valve discs engaged in frictional, sealed face to face disposition and includes plural axially parallel through passageways arranged for selective communication, one disc being rotatable relative to the other. Plural dedicated flow paths are defined by said passageways for metering, storing and delivering precise volume aliquots of sample, of diluent and of lysing reagent (in respect of blood cell study) from sources of said liquids to mixing and/or testing chambers. Vacuum is employed to move the liquids along the dedicated flow paths aiding in prevention leakage from the junctions of the passageways within the valve assembly along the engaged surfaces.
