Abstract: A liquid handling system includes flow network module structure that defines a contained array of flow channels and a plurality of valves for controlling liquid flow through the flow channel array. The flow network module structure is adapted to be connected to an external source for applying a pressure differential to the flow network array to produce liquid flow within passages of the array. Also incorporated in the flow network module is chamber structure that is connected to the flow channel array and that has port structure in an outer surface of the module structure. Valve structure on the module structure is movable between a first position in which the port structure is closed and a second position in which the port structure is opened, the valve structure including actuator structure for moving a valve member between the first and second positions. Liquid transfer structure, including transport structure and probe structure carried on the transport structure, is adapted to cause movement of the valve structure from its first position to its second position concurrently with the movement of the probe structure into alignment with the chamber port structure for delivery of a quantity of sample material to the sample chamber and subsequent flow through the flow network array for interaction with an auxiliary fluid and transfer to an associated utilization device under the influence of an external pressure source.
