High-performance Agilent 1100 Series G1311A quaternary HPLC pump for flexible gradient elution in liquid chromatography.
The Agilent Technologies 1100 Series Quaternary Pump G1311A is a precision liquid chromatography pump designed to deliver accurate and reproducible solvent flow in HPLC systems. Featuring a quaternary solvent mixing configuration, this pump enables flexible gradient elution essential for complex sample separations in molecular diagnostics and bioprocessing research.
Widely used in analytical chemistry, biomedical engineering, and synthetic biology research, the G1311A is critical for applications involving gradient elution chromatography, liquid chromatography-mass spectrometry (LC-MS) sample preparation, and quantitative bioanalysis. Its robustness and flexibility make it a valuable asset in laboratories focusing on molecular cloning workflows and clinical diagnostics requiring high solvent mixing accuracy.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
