Harvard Apparatus PHD Ultra Syringe Pump

Description

Harvard Apparatus PHD Ultra and PHD 2000 Syringe Pumps

The Harvard Apparatus PHD syringe Pumps are built to handle either infusion or infusion and withdrawal. They provide high accuracy for flexible use in mass spectroscopy, calibration, drug and nutritional infusions, microdialysis, dispensing chromatography, and LC/HPLC applications. These microprocessor-controlled syringe pumps feature an easy-to-navigate full-color touch screen that displays operation in real time with on-screen graphics. This unit also comes with preprogrammed methods.

The small step-angle stepping motor of the PHD Ultra drives a lead screw and pusher block, with a step rate range of 26 µsec to 27 sec per µstep, to eliminate flow pulsation. Depending on the syringe, the flow rate is between 1.56 pl/min- 216 ml/min, with a flow accuracy of 0.35% and reproducibility within 0.05%. The accompanying software for the Harvard PHD Ultra and touch color display allows users to create methods from selecting common syringe models, inputting custom specifications, calculating cross-sectional areas, and calibrating the flow rate and volume accumulation.

The Harvard PHD 2000 Syringe Pump provides reliable and steady infusion with microprocessor control and high accuracy. This infusion pump holds two syringes and can hold syringes from 0.5uL to 140 mL. The flow rate of this syringe pump provides smooth advancement and super low rates, with a micro-stepping motor that can get down to 0.0001 uL/hour and is very quiet while operating. This infusion pump is simple to work with a digital, bright, easy-to-read display and numerical touch keypad. The Harvard PHD 2000 Syringe Pump delivers an average nominal force of 50 lbs and has an accuracy of 0.35% and a reproducibility within 0.05%.
