ALZET Micro Osmotic Pumps）
Alzet Osmotic Pumps are osmotic pumps with a volume of only capsule size, which can be implanted subcutaneously or intraperitoneally in experimental animals to continuously and accurately administer test agents at a rate of µ l/hour, directly or through a catheter. This infusion can last for up to 6 weeks under the condition of the animal being awake and unrestrained, depending on the pump used.

Advantages of ALZET Micro Osmotic Pump -Ensure continuous exposure to the predetermined level of test drug -Can perform short-term administration of proteins and peptides -Provides a simple method for chronic quantitative administration in animals -Solved the inconvenience of administering medication at night and on weekends -Reduced the handling and stress effects on experimental animals -Small enough to be applied to mice and young rats -Can be administered to almost any organization -A cost-effective research tool

Alzet Osmotic Pumps comply with USP Medical Plastic Material Biocompatibility Standards and are suitable for implantation into experimental animals for specific site administration or for introducing drugs into the site of action through catheters, such as:Tumors and injuries in the spinal cord and cranial cavity, blood vessels, liver, spleen, and other organs.
Alzet pumps have successfully transported hundreds of drugs in 8000 life science experiments worldwide,Including proteins, peptides, growth factors, antisense in gene research and therapy, and the latest interfering RNA (RNAi), Antibiotics, chemotherapy drugs, hormones, steroids, and other short-lived compoundsEspecially in the research of cardiovascular and neurological diseases, continuous administration of ALZET Osmotic pumps can also be effectiveEstablishing animal models for various diseasesAnimal models of hypertension and Parkinson's disease. With the support of thousands of literature, it is able toAnimal cell administration, animal model construction, drug and molecular screening, pharmacological pharmacokinetics and efficacyIt plays an irreplaceable role in many fields.
