Infusion That Fits Your Research

IPRECIO close-up with blue reservoir




iPRECIO Micro Infusion Pumps

All infusible compounds are not created equal, so why should your infusion methods be? There are lots of available laboratory infusion tools for acute studies, static infusion rates, or tethered infusions, but when you need variable, non-tethered, chronic infusion, perhaps you’ve felt that the options are not so obvious.

We understand that sometimes your research requires infusion tools that can adapt to your study designs. The iPRECIO® Micro Infusion Pump from Primetech Corporation is the world’s first implantable, programmable, refillable infusion pump for mice and other small animals. Combined with top-class support from DSI, with the iPRECIO® Micro Infusion Pump, you have accurate, flexible, chronic infusion delivered just the way you need it.

Combine the Power of Telemetry with
High Precision Infusion

IPRECIO System with

A Complete Infusion Telemetry Solution

DSI transmitters are designed to collect and transmit chronic data from conscious freely moving animals. Our comprehensive physiologic monitoring platform provides flexibility and accuracy not available from any other vendor. Telemetric monitoring supports the 3R’s, by reducing animal numbers, refining study design and replacing labor intensive study methods.

Adding telemetry to a chronic infusion protocol using the iPRECIO® infusion pump enables researchers to run better studies and increase the likelihood of new discoveries in various research applications.

Researchers can wirelessly monitor a fully ambulatory infusion model that is chronically delivered test article at accurate rates. The best of both worlds with no wires or tubes.

The Freedom to Deliver Substances During  Behavioral Assessments  

01 IR Actimeter


Optimize Your Behavioral Assessments

Methods to administer agents in animal models typically require restraint, sedation or anesthesia, which can all have an impact on animal behavior. Implantable infusion provides full recovery after initial surgery, allowing the animal to return to normal physiological conditions prior to scheduled or continuous administration. This not only improves animal welfare, it also delivers a positive impact on experimental conditions and relevance of the study results achieved.

Common Applications Include: 
  • PKPD Studies
  • Neurodegenerative Diseases
  • Neuromuscular Disorders
  • Mood Disorders
  • Exercise
  • Addiction 
  • Spinal Cord Injury
  • Circadian Rhythm 

Take the Stress Out of Your Respiratory Data

FP WBP 2-Site System - Mouse

Confidently Measure Respiratory Function in Unstressed, Unrestrained Subjects While Infusing

Whole Body Plethysmography (WBP) is a way to measure respiratory function in animals (or people) without the use of anesthesia or restraint. The system relies on a specially designed chamber in which the subject is placed. A sensitive pressure transducer is connected to measure pressure changes inside the chamber. 

The combination of iPRECIO implantable infusion and WBP allows for the collection of respiratory endpoints before, during and after infusion. This is particularly useful when studying depressive effects of opiates, barbiturates, and certain benzodiazepines, the pulmonary effects caused by chemotherapy, heart medications and antibiotics or treatments for pulmonary conditions such as asthma, pulmonary fibrosis and COPD. 

Infusion Applications and References

With a wide range of compatible solvents and vehicles, iPRECIO Micro Infusion pumps are used as a platform to:

  • Evaluate both non-optimized and optimized compounds
  • Maximize the information content about target engagement (PK/PD)
  • Minimize confounding variables due to stress and human interactions
  • Simulate humanized exposure profiles for translational researc
