Abstract
A microfluidic purge valve in a microfluidics system includes a notch defined in the valve seat of a microfluidic valve. The notch is sized so that gas entrained within a liquid pumped through the microfluidics system can pass freely therethrough but the liquid cannot. The notch is sized so that the resistant force generated by the surface tension of the liquid is equal to or greater than the force generated by the fluid pressure.
