Osmotic Pumps

Unique with competitive price, RWD miniature infusion pump is designed for precise and continuous long-term dosing in mice and rats, durations for up to 4 weeks.

It can be implanted subcutaneously or intraperitoneal for systemic administration, or attached to a catheter to provide targeted delivery for the intravenous, intraarterial, brain, or cranial/calvarial infusion.

Overview

The osmotic pump consists of a robust shell under a semi-permeable membrane that allows animals’ fluids to pass through. Built-in high-pressure salt interlayer, which absorbs animal fluids, causing them to expand and squeeze the drug storage capsule. The stored liquid in the capsule can be delivered to specify tissue area continuously and accurately at a constant rate.

Applications

  • Cardiovascular disease model;
  • Addiction Research;
  • Emotion-based research;
  • Medication research for diabetes and other metabolic diseases;
  • Pain, injury, and other therapeutic drug infusions;
  • Cancer Drug Screening;

Tissue area of drug delivery

it can be implanted directly into the peritoneal cavity or the back of the neck to deliver the drug. It can also be applied to specific tissues, such as Vascular, cranial, spinal cord, lung, liver etc., by attaching catheters or other accessories.

Size of Pump

Models: 3 sizes, 100ul, 200ul, and 2ml. The pump rate is stable through in-vivo testing.

Benefits of material

Made by biocompatible material to avoid immune rejection after implantation in rats and mice. Each pump is also sterilized by irradiation to ensure no inflammatory reaction in mice and rats.

Advantages

Stable Pumping Rate

Predictable dosing and minimizes experimental variables to ensure reproducible and consistent results.

Reduced Stress Response to Mice and Rats

Different from the traditional multiple injections, it reduces the stress response by avoiding frequent animal handling, then ensures the experimental results and that animal welfare is guaranteed.

Wide Application, Easy to Perfom

Reducing the need for regular injections at night and weekends. It can be directly subcutaneously or intraperitoneally embedded for systemic drug delivery, or connected to a catheter for use in other specific tissues or organs such as blood vessels, cranial brain, liver, etc.

Clients Say

"Hello Cindy, They seemed to have worked quite well in our first batch of experiments. We are still analyzing and collecting the data but we saw significant cardiac hypertrophy in the mice with Ang-II in the osmotic pumps suggesting the pumps worked."
