Abstract

See full text

A fluid delivery device which delivers microliter and sub-microliter volumes by means of a reciprocating force mechanism requires no capillary contact between the delivery system and work surface. Furthermore, a built-in vacuum-based rinse station permits the user to dispense a variety of fluids while avoiding complex and time consuming changes to the fluid delivery system.
