What is the Harvard Apparatus PHD Ultra™ Syringe Pump?

The Harvard Apparatus PHD Ultra™ is a high-performance, fully programmable syringe pump designed for precision fluid delivery across a wide range of life science and research applications. Featuring an advanced graphical touchscreen interface and a robust mechanical drive mechanism, the PHD Ultra delivers accurate, smooth flow from picoliter-per-minute rates up to 216 ml/min, making it suitable for everything from single-cell microinjection to large-volume animal perfusion.

The PHD Ultra (Infuse/Withdraw) supports two-way operation with a 2-syringe rack accommodating syringe sizes from 0.5 µl to 140 ml. Its intuitive touchscreen with built-in wizards simplifies setup for complex or repetitive protocols, while EZ PRO software enables PC-based control and automation for high-throughput applications.

Key Features

• Exceptional Flow Range: Delivers flow rates from picoliters per minute to 216 ml/min, providing unmatched versatility for microfluidics, cell culture perfusion, microdialysis, and large-volume animal studies.
• Graphical Touchscreen with Wizards: The intuitive touchscreen interface includes built-in programming wizards and templates that simplify complex or repetitive infusion protocols without requiring a PC.
• 2-Syringe Rack (0.5 µl–140 ml): Accommodates a wide range of syringe sizes from the same rack, eliminating the need for separate pump platforms when switching between experiments.
• Advanced Mechanical Drive: A new drive mechanism delivers smoother flow and higher linear force, improving accuracy at low flow rates and reducing pulsation artifacts.
• EZ PRO Software Compatibility: Integrates with Harvard Apparatus EZ PRO software for PC-based programming, data logging, and remote control via USB or RS-485 communication.
• Compatible with HAPC Pump Controller: Can be operated standalone or as a channel within the Harvard Apparatus Pump Controller (HAPC) for centralized multi-pump coordination.
