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.
