Osmotic Pumps

Our osmotic pumps are used for laboratory animals such as mice and rats, to achieve long-term continuous drug delivery in animal experiments.

Once implanted in the animal body, it delivers drugs in a long-term continuous mode using the principle of osmosis.

Small sizes, easy to operate, up to 4-week continuous drug delivery, to save time by eliminating the need for frequent animal handling.

3 models sizes are available: 100μl, 200μl, 2ml.

The mini osmotic pump has become the best tool for continuous dose of unrestrained laboratory animals. It can be implanted subcutaneously or intraperitoneally in animals. With minimal side effects and experimental variables, it reduces the risk of stress due to frequent animal handling. It is used for continuous delivery of a wide range of drugs, including antibodies, growth factors, cytokines, chemotherapeutics, addictive drugs, hormones, steroids and more.

Osmotic Pumps consist of three concentric layers: the inner drug reservoir, the osmotic layer, and the outer. When the pump is implanted, water is absorbed through the outer membrane. The water entering the pump expands the osmotic layer, which compresses the flexible, impermeable reservoir.

Advantages

Animals are continuously infused at the predetermined dose for extended periods, including nights and weekends;
Easy to use, without complex programming or software to learn;
Once implanted, they operate unattended for up to 4 weeks, eliminating the need for repetitive dosing & frequent animal handling;
Small size, available for use in mice, rat and larger animals;
Catheter attachment enables direct administration of agents into a specific organ or tissue.
