Syringe Pumps PHD ULTRA™ Push/Pull Syringe Pump SYRINGE PUMPS PHD ULTRA™ Push/Pull Syringe Pump Pressure-driven flow was continuous using a programmable push-pull syringe pump (Harvard Apparatus, Holliston, MA). Media was equilibriated with 10% or 21% O2 in a gas exchanger made with gas-permeable silastic tubing1. KEY FEATURES Compensating Flows: The control of continuous infusion and simultaneous withdrawal of liquids while monitoring fluid levels Perfusion Across Tissue Beds: Directional control of flows across tissue beds using switching valves Continuous Flow with High Accuracy and Smooth Flow: Pump Any Volume Large or Small with Smooth, Non Pulsating Flow Continuous Accurate Flow for High Pressure Systems: Unlike peristaltic pumps, syringe pumps can pump against high pressures Easily Sterilized Flow Path: By replacing syringe and tubing with a sterilized set, this pump can maintain it’s sterility The PHD ULTRA™ Push-Pull syringe pump provides virtually pulse free, high accuracy and high precision flow. Complex programs can be written using on-board EZ Pro software to reduce shear stress during cell deposition and adhesion during tissue and organ development. Conversely, the same complex programs can be used to create particular shear forces on developing cells. The PHD ULTRA™ Push Pull combines the high accuracy of our ULTRA line of pumps. Harvard Apparatus also has a wide array of temperature control products to provide complete environmental control. Our 2 year warranty and robust construction allow these pumps to work continuously for extended periods of time with unsurpassed reliability. For complete specifications see facing page.
