Single-stage brass oxygen regulator with dual gauges (CGA 540) for precise gas pressure control in laboratory applications.
The Liquid Air 104HDF-O2-158 is a single-stage brass oxygen regulator designed for accurate pressure regulation in laboratory gas delivery systems. Featuring dual pressure gauges, it monitors both inlet and outlet pressures to ensure reliable control of oxygen flow from compressed gas cylinders with CGA 540 fittings. This regulator is essential for applications requiring stable oxygen delivery such as molecular diagnostics, bioprocessing, and biomedical engineering workflows. Its corrosion-resistant brass body provides durability and longevity under rigorous laboratory conditions. Widely used in synthetic biology research and clinical diagnostics, the 104HDF-O2-158 supports safe and precise oxygen regulation critical to biomanufacturing and cell culture processes.
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.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options 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.
