Abstract: A biological fluid sample analysis cartridge is provided that includes a collection port and a body. The body has one or more internal channels in selective fluid communication with the collection port. The collection port includes a collection bowl, and a slide valve assembly operable to be selectively positioned in an open position and a closed position. In the open position, the collection bowl is accessible for sample deposition, and in the closed position the collection bowl is inaccessible for sample deposition.

Abstract: Flexible pouch and flexible cartridge devices for fluid sample processing, related methods of making and using, related manufacturing systems and related instrumentation systems are described. Flexible pouches provide broad advantage in a wide variety of fields by overcoming the need for complex instrumentation, dedicated devices, and relatively high cost in conventional fluid sample devices. Flexible cartridge devices are particularly advantageous in control of fluid handling, rapid adaptation to a number of configurations by the end user, multiple uses for a single configuration, and in cost and ease of manufacture.

Abstract: A system for dispensing microdrops of reagent in small, precisely metered quantities maintains the fluid reagent to be dispensed in a reservoir under a controlled pressure. The reagent is dispensed through multiple nozzles connected to solenoid-actuated valves that control the flow of the reagent from the reservoir to the nozzles. Each valve is connected to one of the nozzles and electrical pulses are supplied separately to each of the valves to separately control the opening and closing of each valve to dispense predetermined quantities of the reagent through each nozzle at predetermined times.

Abstract: An array of reaction assemblies for heating and cooling a plurality of reaction vessels. Each reaction vessel assembly including a heat conductive reaction block having an exterior wall and a reaction vessel receiving cavity formed in the block inwardly of the exterior wall. A thermoelectric module is mounted in heat transfer engagement with the exterior wall of the heat conductive reaction block. A fluid heat exchange element is mounted in heat transfer engagement with the thermoelectric module. The thermoelectric module has its junctions to selectively remove heat from the exterior wall of the reaction block or to supply heat to this exterior wall. Each thermoelectric module has thermoelectric junctions cascaded for increased heating and cooling range and a plurality of these junctions to increase capacity.
