ABSTRACT:
An apparatus for mixing and dispensing particulate-laden liquid or immiscible liquid, samples from a container or vessel. The apparatus is attached to the top of the vessel with a mixing tube extending downwardly into the liquid sample. A valve piston disposed in the tube may be moved from a closed position to an open position while the liquid sample is continuously agitated and circulated through the mixing tube. The agitation system lifts a portion of the liquid sample through the valve piston and out a discharge port for eventual assaying.
