A manifold device is provided for use with a valve assembly, an aspiration source and a dispensing source to transfer fluid from at least one of a plurality of fluid reservoirs to at least one test site on a substrate surface. The manifold device includes a manifold body that defines a plurality of fluid aspiration conduits, for fluid aspiration in an aspiration position, and a plurality of fluid dispensing conduits to selectively dispense at least one droplet of the corresponding liquid sample slug, in a dispensing position. In the aspiration position, the respective sample paths are out of fluid communication with the dispensing source and, in the dispensing position, the respective sample paths are out of fluid communication with the aspiration source.
