Product description

Agilent G1312B binary HPLC pump with 5.0 mL/min flow and operation up to 600 bar.

The Agilent 1260 Infinity G1312B Binary HPLC Pump is an analytical HPLC solvent delivery module designed for high-pressure gradient formation through binary high-pressure mixing. Its dual-channel, series-connected dual-piston architecture supports precise solvent metering for liquid chromatography, pharmaceutical analysis, biotechnology workflows, and molecular diagnostics.

Key Features

  • Binary gradient pump with two integrated, identical pump assemblies
  • High-pressure gradient mixing for analytical HPLC applications
  • Flow rate up to 5.0 mL/min
  • Flow range of 0.05 to 5.0 mL/min
  • Operating pressure up to 600 bar (7,800 psi) at flow rates up to 5 mL/min
  • Rapid conversion between standard and low-delay-volume configurations
  • Strong gradient performance at low B-solvent percentages and narrow flow rates
  • Electronic damping control for reduced baseline noise
  • Each pump assembly includes a pump drive, pump head, active inlet valve with replaceable cartridge, and outlet valve

Technical Specifications

  • Weight: 15.5 kg
  • Dimensions (W × D × H): 180 × 345 × 435 mm
  • Flow accuracy: ±1% or 10 µL/min, whichever is greater
  • Pressure: Up to 600 bar (7,800 psi), according to the listed operating specification

The listing also references a pressure capability of up to 400 bar in the general description. Buyers should verify the exact pressure configuration and operating limits of the individual unit before integration into an HPLC system.

Included

  • Agilent 1200 Series G1312B binary pump
  • Power cable
  • Operating manual provided as a PDF by email

This Agilent binary HPLC pump has been function-tested and is suitable for analytical liquid chromatography, gradient separations, biotechnology research, and biopharmaceutical laboratory workflows.

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.
