H Pumps Harvard Apparatus SYRINGE PUMPS arvard Apparatus offers a broad selection of syringe, peristaltic and continuous flow pumps to suit almost every application. Syringe pump models have been expanded to include new innovative pumps with the widest range of flow rates and forces of any manufacturer. Recent additions are the PHD ULTRA™ CP, capable of delivering flow at constant pressure, and the PHD ULTRA™ XF with force capability in excess of 1,000 lbs., ideal for high flow rates and viscous solutions. With more than 100 years of success and a proven track record of designing and manufacturing high quality reliable syringe and peristaltic pumps, only Harvard Apparatus has the scientific depth and fluidics knowledge to recommend the right pump and accessories for your application. Our superior technical experts are available to assist you from start to finish. Harvard Apparatus invented the lead screw based syringe pump in the 1950’s and introduced the first microprocessor pump, in the 1980’s. Our syringe pumps are so accurate, even at low flow rates, that they have become the standard for mass spectrometry calibration, animal infusion and anywhere accurate volumes must be delivered. Our PHD ULTRA™ and Pump 11 Elite Series have set a new standard in syringe pumps. They are easy to use with an intuitive interface controlled via touch screen. The PHD ULTRA™ and Pump 11 Elite are suitable for a wide range of applications including mass spec calibration, drug and nutritional studies, macro to micro reactors, LP chromatography, electrospinning, aerosols and macrofluidics to microfluidics. Running a syringe pump has never been easier. The Pump 11 Pico Plus Elite is best suited for low flow rate studies and small volume injections. It is ideal for applications including: microdialysis, animal drug and nutritional studies, cellular injection, and more. The NEW Harvard Peristaltic Pumps provide digital control over a wide range of flow rates for applications including: dispensing/dilution, organ/tissue perfusion, and fluid circulation. Harvard Apparatus offers an expanded line of component pumping modules for OEM and specialized system development. Pump 11 Pico Plus Elite Results you can count on! Since 2011, there have been more than 2,000 scientific publications referencing the use of Harvard Apparatus pumps in areas including: infusion, microfluidics, perfusion, electrospinning, and more. You can count on our expert technical support to provide product recommendations and application support to advance your studies. If you don’t find what you need, please contact us!
