Precision liquid delivery with dual pistons, low-pressure mixing capabilities.
The Agilent 1100 Quaternary Pump model G1311A is engineered to deliver near pulse-free and stable solvent flow, featuring dual floating pistons in series with precision servo control. It offers a settable flow range from 0.001 to 10 ml/min, adjustable in 0.001 ml/min increments, supporting a flow range between 0.2 and 10.0 ml/min. With a pH range capability from 1.0 to 12.5, it is important to avoid using solvents with pH > 2.3 that contain acids harmful to stainless steel. The pump is equipped with low pressure quaternary mixing and gradient capabilities, utilizing a proprietary high-speed proportioning valve. The delay volume ranges from 800 to 1100 µl, depending upon back pressure. Ideal for precision liquid chromatography applications, this pump ensures optimal performance and reliability for advanced research needs.
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.
