NanoFab Tool: Microfluidic Test Station

Photo Microfluidic Test Station

The CorSolutions microfluidic test station consists of a digital microscope, PneuWave pneumatic pump, and microfluidic probes to enable non-destructive, rapid connection and testing of micro- and nano-fluidic devices. This system provides closed-loop control of fluid by pressurizing the fluid vessel, then measuring the resulting fluid flow. This technique provides pulse-free flow with a fast response time to changing flow rates or pressure. The system is also capable of fully programmable fluid delivery and user-defined pressure profiles (including ramp up & ramp down) with simultaneous data logging. This system can accommodate devices up to 4 inches by 6 inches. 

Specifications/Capabilities

  • XY translational stage with 4-inch by 6-inch travel
  • Top and bottom LED illumination
  • Digital microscope with 25X to 200X magnification, motorized Z axis
  • Four fluidic connectors (1/16 & 1/32 inch tubing gaskets)
  • Closed loop, flow control of 2 independent fluid channels (0.1-50µL/min)
  • Pulse-free flow with fast response time 
  • Voltage probe mount
