The PHD ULTRA
TM
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
TM
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.

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 Flo
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
Pressure-driven flow was continuous using a programmable push-pull syringe pump
(Harvard Apparatus, Holliston, MA). Media was equilibriated with 10% or 21% O
