Harvard Apparatus PHD ULTRA 703007 Syringe Pump

Harvard Apparatus PHD ULTRA syringe pump, catalog number 703007, a microprocessor-controlled infusion/withdrawal syringe pump used in laboratory and R&D settings for precise, programmable fluid delivery in microfluidics, dosing, calibration and general dispensing work. The unit is a self-contained benchtop pump with a color touchscreen interface on the front panel, allowing pumping methods to be set up and run directly at the pump without a computer. The pump carries a dual syringe rack on the pusher block, with adjustable clamp bars and retaining posts for holding multiple syringes side by side. The rear panel provides RS-232, USB, RS-485 in/out for daisy-chaining multiple pumps, a 15-pin digital I/O connector, foot switch input, analog in #1/#2 and analog out #1/#2 positions, a power switch and an IEC inlet with fuse holder. The nameplate shows the unit is rated 100-240 VAC, 50/60 Hz, 0.5 A, and is ETL listed, CE marked, FCC and RoHS compliant. The pump is shown as removed from service and sitting on a bench. The rear panel nameplate on the pictured unit reads Catalog No. 703007, Serial No. D-401318, while the listing records serial D-401410; the serial should be confirmed against the asset at pickup. A handwritten yellow label on the left side of the housing reads "modified feed rate," and the unit carries a facility asset tag and internal routing tags. Condition, operating hours and functional status were not reported, and no syringes, cables or accessories other than what is visible in the photos are included.
