High-purity 99.9995% hydrogen generator delivering 160 ml/min at 0.3–6.89 barg for GC use.
The Parker Hydrogen Generator 20H is designed to provide a reliable hydrogen gas supply for gas chromatography (GC) applications. It delivers a flow rate of 160 ml/min with a hydrogen purity of 99.9995%, operating at a pressure range between 0.3 and 6.89 barg. This generator is essential for laboratories engaged in molecular diagnostics, biotechnology, and analytical chemistry, where stable and ultra-high purity hydrogen is critical for accurate chromatographic analysis. Its precise pressure control and consistent output make it ideal for bioprocessing workflows and synthetic biology research requiring dependable gas sources. The hydrogen purity and flow specifications ensure optimal performance in fluorescence analysis and other sensitive detection methods in clinical diagnostics and biomedical engineering fields.
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.
