  Title A single channel capillary microviscometer Type Journal Article
  Year 2013 Publication Microfluidics and Nanofluidics Abbreviated Journal Microfluid Nanofluid  
  Volume 15 Issue 4 Pages 475-479  
  Abstract We have developed a microviscometer analyzing the fluid dynamics in a single

channel glass microfluidic chip with a closed end. The device is able to test sample

volumes of a few microliters by inserting one drop in the inlet. The fluid enters the

channel driven by capillary pressure and an optical sensor registers the motion. The

equation that describes the fluid dynamics is function of the channel geometry,

atmospheric pressure, fluid viscosity and capillary pressure. Knowing the first two the

last parameters can be obtained as fitting parameters from the meniscus position as a

function of time plot. We have successfully tested Newtonian fluids with different

viscosities and capillary pressure.
