Micropumps controllable flow rate pump

A miniature fluid system usually handles trans-portatiOTi of fluids filled with particles and/or biomacromolecules such as protein solution or cell lysate. This system, also called a microfluidic system, works with a flow rate of the order of pl/s to nl/s and where its microchaiuiels have diameters less that a millimeter. Due to the small flow rate required by the system, it depends Ml micropumping to provide the fluid flow. A micropump, a device that produces a small-scale fluid flow, uses electrical or mechanical stimulus to drive the flow [3]. An example of a pump used in micropumping is the syringe prrmp. Crment trends are to develop microfluidic systems for precise control of gas and liquid flows. The designs typically consist of integrated microfluidic components such as pumps, valves, and sensors [4].
