Harvard Apparatus PHD Ultra Microprocessor-Controlled Precision Syringe Pump with Dual Syringe Capability

The Harvard Apparatus PHD Ultra Syringe Pump is a microprocessor-controlled laboratory infusion system engineered for precise fluid delivery critical in biotechnology, molecular diagnostics, and bioprocessing applications. Featuring dual syringe capability, it supports both infusion and withdrawal functions with continuous operation mode.

Key technical specifications include:

• Flow rate range: from 1.56 picoliters/min (using a 0.5 µl syringe) up to 216 ml/min (using a 140 ml syringe), accommodating a wide range of volumetric scales for biomanufacturing and synthetic biology workflows.
• Flow accuracy: ±0.25% and reproducibility within 0.05%, ensuring reliable dosing for gene editing and calibration tasks.
• Driven by a 0.9° stepper motor with a small step-angle mechanism delivering microsteps at rates between 26 µsec and 27.5 seconds per microstep, effectively eliminating flow pulsation—essential for sensitive live-cell imaging and LC/HPLC analytical protocols.
• Programmable full-color touch screen interface with preprogrammed methods simplifies setup and calibration, integrating cross-sectional syringe data input for precise flow and volume control.
• Mechanical performance: max linear force of 75 lbs at full force selection and pusher travel rates ranging from 0.18 µm/min to 190.8 mm/min, making it suitable for demanding drug infusion and chromatography applications in clinical diagnostics.
• Environmental specs: operates efficiently within 4°C to 40°C temperature and 20% to 80% non-condensing humidity, compatible with typical laboratory conditions.
• Compact footprint (13 x 15 x 9 inches) and 11 lbs weight facilitate benchtop placement in cell biology and mass spectrometry research labs.

This pump is widely adopted in biotechnology research environments that require high precision fluid handling, including molecular cloning experiments and biopharmaceutical production pipelines. The embedded software enhances versatility by allowing users to create custom protocols, supporting advanced workflows in synthetic biology research and bioprocessing optimization.

Optimized for laboratory scientists, researchers, and medical professionals, the Harvard Apparatus PHD Ultra Syringe Pump delivers scalable precision and reproducibility essential for critical biomedical engineering and fluorescence analysis applications.
