The World's First Totally Implantable, Programmable Micro Infusion Pumps for Mice and Small Animal Infusion

  • Models available for mice (SMP-310) or rats (SMP-200)
    • Accurate patented Rotary Finger Method. Every pump is factory tested and calibrated
    • Better than ±5% accuracy
    • Programmable infusions protocols (simple and complex)
  • Totally implanted in subcutaneous space
  • Refillable (reservoir) percutaneously via refill port with re-sealable septum
  • With iPRECIO® catheters, test your drug's effects nearly anywhere
  • Easy to use menu driven software for infusion protocol programming


The pump can be completely implanted in small laboratory animals subcutaneously. Thus, the animal moves freely without any restrain (i.e. tethering) during drug infusion. Additionally, infection risk is reduced, and the animal is likely to be significantly less stressed than in a tethered infusion model.


You can replenish any medical fluid in the pump via percutaneous access to the pump refill septum and reservoir after implantation of the pump.
So, long-term drug infusion can continue until the installed battery life has run out.
The reservoir is elastic and configured in such a geometry as to allow gentle palpation to confirm an approximate level of fluid in the reservoir.

Refillable pump


Using the easy to use state of the art iPRECIO® software, header information along with infusion protocol details are entered and ultimately downloaded to the pump's memory. See individual pump model pages for specifications on flow rates and available modes.

The programmable feature will make iPRECIO pumps indispensable for applications where accurate flow infusion, recovery/washout periods, constant/variable dose or complex circadian infusion studies are necessary.



The technology driving the infusion is a patented "Rotary Finger" method. This method is a unique form of peristalsis. The precise "micro-stick" pushes a rubber tube in the pump in a uniform and sequential manner. The accuracy of iPRECIO is +/-5%.
