Infusion pumps, on the other hand, are designed for delivering larger volumes of fluids over an extended period.[9] Unlike syringe pumps, infusion pumps can accommodate a broader range of fluids and medications, making them versatile tools in various laboratory settings. They provide continuous and controlled infusion, ensuring receiving the necessary medications or fluids at the prescribed rate and duration. They can be used in:

1. Drug Infusion in Animal Studies: Infusion pumps enable precise and controlled administration of drugs to animals in research studies, ensuring accurate dosing and minimizing variability in drug delivery.
2. Microdialysis Experiments: Infusion pumps are utilized in microdialysis techniques to deliver perfusion fluid at a constant rate, allowing for the collection of small-molecule analytes from extracellular fluid in animal models for pharmacokinetic studies or neurochemical monitoring.
3. Continuous Infusion in Physiology Experiments: In physiological research, infusion pumps are used for continuous delivery of fluids or substances to animal models, facilitating experiments such as glucose tolerance tests, hormone infusion studies, or drug metabolism investigations.
4. Tissue Perfusion Systems: Infusion pumps are integral components of tissue perfusion systems used in ex vivo experiments, enabling researchers to maintain organ or tissue viability by delivering oxygenated perfusate with nutrients and maintaining physiological conditions.
5. Drug Screening Assays: In laboratory settings, infusion pumps are employed in automated drug screening assays to deliver test compounds or candidate drugs to cell cultures or biological samples at precise concentrations and rates, facilitating high-throughput screening studies.
6. In Vitro Pharmacology Studies: Infusion pumps are utilized in in vitro pharmacology experiments to mimic physiological conditions by continuously delivering substances to cell cultures or tissue preparations, allowing for the investigation of pharmacological responses and drug interactions.
7. Behavioral Studies in Animal Models: In behavioral research, infusion pumps are used to deliver substances such as drugs, neurotransmitters, or neuromodulators directly into the brain or peripheral circulation of animal models, enabling researchers to study the effects on behavior and neural circuits.
8. Perfusion of Isolated Organs: Infusion pumps are employed in the perfusion of isolated organs such as hearts or kidneys in ex vivo experiments, allowing researchers to study organ function, metabolism, or responses to pharmacological interventions under controlled conditions.
