Shimadzu DGU-20A5R degassing unit removes dissolved gases from HPLC mobile phases, enhancing chromatographic stability.
The Shimadzu Prominence DGU-20A5R is a specialized degassing unit engineered for high-performance liquid chromatography (HPLC) systems. It effectively eliminates dissolved gases from mobile phases, which is critical for maintaining a stable baseline and ensuring precise chromatographic results in analytical chemistry and molecular diagnostics workflows. Its compact design (16.5 x 15.7 x 4.4 inches) and lightweight (8.8 lbs) enable seamless integration into biotechnology laboratories focused on bioprocessing and gene editing applications.
Key technical specifications include:
This degasser is indispensable in biopharmaceutical production pipelines and synthetic biology research where precise mobile phase conditions are fundamental. It supports fluorescence analysis, live-cell imaging sample preparation, and other biotechnology research requiring solvent purity and chromatographic consistency. The DGU-20A5R is widely adopted among molecular biology researchers and clinical diagnostic laboratories for its robust performance in removing gas interference during chromatographic separation.
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.
