Product description

Precision digital syringe pump with flow rates from 0.002 µL/hr to 55.1 mL/min, ideal for molecular diagnostics.

The Harvard Apparatus 55-2222 Digital Syringe Pump is a precision fluid delivery system widely used in biotechnology, molecular diagnostics, and bioprocessing workflows. Designed for accurate control of infusion and withdrawal rates, this digital syringe pump supports syringe volumes ranging from 0.5 µL up to 140 mL.

Key technical features include:

  • Flow rate range: 0.002 µL/hr to 55.1 mL/min, adaptable for low-volume microfluidic and high-throughput applications.
  • User interface: LED display with numeric keypad allows precise input of syringe diameter and flow parameters.
  • Units of flow: Configurable in µL/hr, µL/min, mL/hr, and mL/min to suit diverse experimental protocols.
  • Optical encoder: Ensures accurate monitoring of lead screw rotation for maintaining constant flow rates during long-term biomanufacturing processes.
  • Safety indicator: Run LED flashes if syringe plunger motion ceases unexpectedly, critical for maintaining flow consistency in gene editing and synthetic biology research.
  • Connectivity: RS-232 remote interface facilitates integration into automated bioprocess control systems and laboratory instrumentation networks.

The 55-2222 model is essential for molecular cloning workflows requiring reproducible and stable fluid handling and is popular among researchers conducting live-cell imaging, fluorescence analysis, and biomedical engineering studies. This syringe pump’s robust build quality and versatility make it a standard choice in clinical diagnostics and biopharmaceutical production pipelines.

*Note: Syringes are not included but can be sourced separately depending on experimental needs.*

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
