WPI Two-syringe Microdialysis Pump

Syringe pumps for high metering precision at low, pulse-free rates

World Precision Instruments

Developed especially for use in microdialysis experiments, the SP101iZ from WPI produces very fine syringe movement. The modified SP100i gearing features a sixfold gear reduction compared to standard models allowing pumping at much smaller flow rates. The SP101i is a dual barrel infusion only pump.



  • Automatic dispensing of small volumes
  • Very precise flow rate control
  • Hands-free operation with foot pedal
  • Better flow performance with accuracy +/- 0.35%


The SP101iZ is sturdy, reliable and extremely simple to set up and use with an LCD to prompt you through setup. First, select the syringe from the table stored in the pump's memory and displayed on the LCD. Next, enter the volume to be dispensed. Finally, enter the flow rate, press "start". Its fast and simple. Your settings are permanently stored in memory - there's no need to re-enter them each day. The volume dispensed is tracked continuously on the LCD, then when the preset volume has been dispensed, the pump shuts off automatically.
