Product description

Stainless steel hydrogen regulator with 4000 PSIG max inlet, 316L diaphragm, 360° filtration, for high-purity gas control.

The Liquid Air 2122381-350 hydrogen regulator is engineered for precise primary pressure control of non-corrosive, high-purity, or liquefied gases up to grade 4.5. Constructed with a 316L stainless steel diaphragm, it effectively prevents inboard diffusion, ensuring integrity in sensitive gas delivery systems critical for biotechnology and molecular diagnostics.

Key features include:

  • Maximum inlet pressure: 4000 PSIG, suitable for demanding laboratory and bioprocessing gas applications.
  • CAPSULE seat design with integral 360° filtration across both stages, optimizing particle retention and flow stability.
  • Standard relief valve incorporated to safeguard diaphragm and gauges, enhancing operational safety in controlled environments.
  • High flow capacity facilitates simultaneous usage at multiple laboratory or biomanufacturing stations.
  • Spectrometric helium leak testing assures leak integrity, critical for maintaining ultra-high purity during synthetic biology and biopharmaceutical gas delivery pipelines.

This stainless steel hydrogen regulator supports consistent pressure control regardless of supply pressure fluctuations, making it essential for molecular cloning workflows, live-cell imaging gas environments, and bioprocessing gas regulation in advanced biotechnology research.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Yes. Every verified supplier states which service partners cover the instrument, and we list that alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
