Abstract
A containment device, such as a cuvette, for use in amplifying and detecting nucleic acid material at a contained detection site. A waste compartment provided downstream from the detection site is provided with fold lines that give the compartment a bi-stable configuration, so that it can expand to relieve back-pressure that otherwise builds up in such a containment device. Also, optimal locations of flow paths between compartments are described to minimize back-flow of upstream reagents into the feeder paths that are yet to be used by subsequent compartments.
