ABSTRACT OF THE DISCLOSURE A metering apparatus is adaptable either as a dispenser or a sampler, the surface of the aspirating probe being coated with a thin film of liquid immiscible with the liquids to be aspirated. The thin immiscible film prevents contamination between segments of successively aspirated liquids and, also, their respective sources. Further, segments of the immiscible liquid can be aspirated between successive liquid segments, to maintain such liquid segments discrete. -1-
