Bomba de Laboratorio Harvard Apparatus 703007

Harvard Apparatus PHD ULTRA syringe pump, catalog number 703007, serial number B-71243. The PHD ULTRA is a microprocessor-controlled infusion/withdrawal syringe pump used in R&D and analytical laboratories for precise, programmable fluid delivery in microfluidics, dosing, calibration and general dispensing applications. It is a self-contained benchtop unit with a color touchscreen interface on the front panel, allowing pumping methods to be entered and run directly at the pump without a connected computer. The pump is built on a stepper-motor driven lead screw and guide rail assembly with a moving pusher block, and carries a multi-position syringe rack with clamp bars and retaining posts for holding syringes on the rack. The rear panel, visible in photos 2 and 3, provides an RS-232 port, USB, RS-485 in/out for daisy-chaining multiple pumps, a 15-pin digital I/O connector, analog in, a foot switch jack, a remote pump communication position, the power rocker switch and the fused IEC inlet. The nameplate lists 100-240 VAC, 50/60 Hz, 0.5 A operation and carries CE, ETL and RoHS markings, along with a caution label noting the unit is for research use only and not for clinical use on patients. The unit is shown as-removed on a lab bench with its IEC power cord present. Cosmetically the chassis and pusher block show paint spatter and general lab wear. Condition beyond what the photos show was not recorded; the display is not lit in any photo, so operation has not been verified. Sold as-is, for inspection by the buyer.
