Gas regulator YR-90 for O2, N2, Ar, H2, He, N2O, CO2 with 0.2–0.99 MPa outlet pressure, ideal for gas flow control in labs.
The Yamato YR-90 Gas Regulator is designed for precise control of inert and reactive laboratory gases including oxygen (O2), nitrogen (N2), argon (Ar), hydrogen (H2), helium (He), nitrous oxide (N2O), and carbon dioxide (CO2). It features a robust C3604B brass body, FKM plus PTFE diaphragm, and PCTFE valve materials providing chemical resistance and mechanical durability suitable for diverse bioprocessing and molecular diagnostics environments. The regulator supports inlet pressures from 2 to 15 MPa and delivers a stable outlet working pressure from 0.2 to 0.99 MPa, with a standard flow rate of 120 L/min and a maximum flow capacity of 150 L/min for nitrogen, ensuring controlled gas delivery essential for synthetic biology workflows and clinical diagnostics. Operating temperature spans from -10°C to 40°C, with a design limit up to 75°C. Its integrated 40 μm filter prevents particulate contamination, key for maintaining purity in biomanufacturing and laboratory synthetic biology applications. Weighing 1.4 kg, the YR-90 gas regulator is a compact and reliable solution widely employed in biotechnology research laboratories requiring precise gas flow control for bioprocessing and cell culture systems. Please note this unit is *used and sold as-is*, and may not meet original new performance standards—confirm conditions prior to purchase.
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.
