Precision Agilent 1100 Series G1311A quaternary pump delivers accurate solvent gradients in HPLC systems.
The Agilent Technologies 1100 Series Quaternary Pump G1311A is a robust HPLC pump engineered for precision solvent delivery in high-performance liquid chromatography workflows. Featuring a quaternary solvent mixing configuration, it supports four independent solvent channels enabling complex gradient elutions essential for accurate analytical chromatography.
This pump is critical in bioprocessing and molecular diagnostics research where reproducible gradient elution and solvent accuracy directly impact compound separation and quantitation. Its modular design facilitates integration into biopharmaceutical production pipelines and synthetic biology laboratories requiring reliable high-pressure solvent delivery. The G1311A model supports advanced applications such as gene editing workflow analyses and complex liquid chromatography-mass spectrometry (LC-MS) setups, making it an essential instrument in biotechnology and clinical diagnostics.
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.
