Used two-stage helium gas regulator with dual pressure gauges and manual pressure adjustment.
The Koike Sanso Kogyo PPR-HE is a used helium gas regulator designed to reduce high-pressure helium from a gas cylinder to a stable lower delivery pressure for laboratory equipment and analytical instruments.
The dual-gauge configuration enables operators to monitor cylinder residual pressure and secondary-side pressure during helium supply. Its compact design is suitable for installation near experimental systems, gas analysis equipment, and other laboratory instrumentation requiring controlled helium delivery.
*This is used laboratory equipment sold as-is. Original performance and functionality may differ from new-equipment specifications.*
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.
