Assembling the NIST Microfluidic Device

Caption

Double-sided tape is cut with channels and ports that will align when folded (A). The polymer membrane that supplies the valve function for the microfluidic device is sandwiched between (B). The completed apparatus (C) has ports for fluid flow into and out of the device, as well as a valve inlet for air. Air pressure pushes the membrane into the flow channel, blocking fluid movement.
