ABSTRACT:
A microfluidic analyzer module. The module is constructed of a plurality of channel forming laminate layers that are directly bonded together without adhesive or other possible contaminant source located proximate the flow channels. The channel forming laminate layers define a network of fluid flow channels. A valve containing layer is directly, adhesivelessly bonded over the channel containing layers. A flexible valve member integral with the valve layer opens and closes communication between feed and sensor channels of the channel network.
