Microfluidic multi-splitter
First Claim
Patent Images
1. A microfluidic device comprising:
- a plurality of device layers wherein at least two of the device layers are stencil layers;
wherein the stencil layers define a first forked channel, a second forked channel, and a third forked channel;
wherein the second forked channel is in fluid communication with the first forked channel at a first overlap region;
wherein the third forked channel is in fluid communication with the first forked channel at a second overlap region.

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.
