RWD Osmotic Pumps

With competitive prices, RWD miniature infusion pumps are designed for precise and continuous long-term dosing in mice and rats, durations for up to 6 weeks, which relieves researchers who are burdened by multiple injections.

Osmotic Pumps can be implanted subcutaneously or intraperitoneally for systemic administration or connected to a catheter to provide targeted delivery for blood vessels, brain, spinal cord, lung, liver, or other specific areas of infusion.

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

The pump can be implanted directly into the peritoneal cavity or the back of the neck to deliver the drug. The pump rate is stable through in-vivo testing.

*Made of 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.

Applications include cardiovascular disease model, addiction research, emotion-based research, medication research for diabetes and other metabolic diseases, pain, injury, and other therapeutic drug infusions, and cancer drug screening.

• Predictable dosing minimizes experimental variables to ensure reproducible and consistent results.
• Reduces the stress response by continuous administration without frequent animal handling. Ensures experimental results and animal welfare is guaranteed.
• Wide application, easy to operate. Reduces the need for regular injections at night and on weekends.
