What are ALZET® Osmotic Pumps?

ALZET Osmotic Pumps are small, implantable pumps for research in mice, rats, and other laboratory animals.

Sold empty and filled by the researcher, these minipumps deliver drugs, hormones, and other test agents at continuous and controlled rates without the need for external connections or frequent handling. With durations ranging from one day to six weeks, the pumps’ unattended operation eliminates the need for repeated nighttime or weekend dosing by lab personnel. Their use has been described in thousands of studies.

ALZET pumps can deliver systemically when implanted subcutaneously or intraperitoneally or they can be attached to a catheter for targeted delivery in which the effects of a test agent are localized in a particular tissue or organ. These pumps have been used for dosing to a wide variety of sites including the brain, spinal cord, bone, liver, organ or tissue transplants, and wound healing sites.
