High-precision quaternary HPLC pump G1311A delivering flexible solvent gradients for liquid chromatography.
The Agilent Technologies 1100 Series Quaternary Pump G1311A is a high-performance solvent delivery module designed for *liquid chromatography* applications, particularly suited for high-performance liquid chromatography (HPLC) workflows. This quaternary pump supports flexible gradient elution by mixing up to four solvents with high precision, making it essential for *molecular diagnostics*, *bioprocessing*, and *synthetic biology* research where accurate solvent gradients are critical.
Key technical specifications include:
This pump is widely adopted in biotechnology laboratories for precise solvent mixing required in *chromatographic separation*, *gene editing workflows*, and *biopharmaceutical production pipelines*. Its robust design and compatibility make it a critical component in analytical chemistry and biomedical engineering applications focused on *live-cell imaging* and *fluorescence analysis* that depend on reproducible chromatographic methods.
Built in Germany with reliable engineering standards, the G1311A offers stable solvent delivery performance, ensuring consistent and reproducible eluents for research domains such as *cell imaging*, *neuroscience metabolite analysis*, and *clinical diagnostics*. This makes it a preferred choice among scientists requiring precision in gradient-based liquid chromatography workflows, providing versatility in bioprocessing and synthetic biology experiments.
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.
