ABSTRACT:
A splitter for multi-layer microfluidic devices is provided. The splitter includes multiple forked channels defined in two or more device layers. The forked channels communicate fluidically at overlap regions. The overlap regions, in combination with symmetrical channel geometries balance the fluidic impedance in the system and promote even splitting.
