Surface acoustic wave sensor development workstation at the Biophysical Technology Laboratory, Chalmers University of Technology, Göteborg, Sweden.
In this real life measurement situation, the pump utilizes four channels to supply differential pressures, driving sample and washing solutions across a microfluidics-integrated surface acoustic resonance sensor. Operation parameters: Flow rate: 240 nl/s at 250 mbar pressure. The fluid flow passes through a PDMS channel device with 40×40µm quadratic channels, plasma bonded to the silicon oxide-coated SAR/EIS tandem sensor dice. The http-based control interface for the pump is here embedded in a labview GUI, and additionally accessible through web browsers on WiFi-connected PCs and mobile phone devices.
