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


  • Drug administration
  • Chemical applications with slow incorporation of fixed volumes of fluids

Developed especially for use in microdialysis experiments, these pumps produce very fine syringe movement. The modified SP100i gearing features a sixfold gear reduction compared to standard models, allowing pumping at much smaller flow rates. (See sensors such as ISO-NO and Micro-C for detection of dialysates.) The SP101i is a dual barrel infusion only pump.
