Description

A pump of three valves, with a serpentine channel to watch the liquid flow. The chip also has two smaller valves, and a bypass channel with its own pinhole that makes the pump easier to test.

Developed at the Nordin Microfluidic and 3D Printing Lab, Brigham Young University.

Prints in a custom resin with NPS or avobenzone as the UV absorber.
