Product description

Stainless steel compressed air regulator for high-purity gases up to 4000 PSIG, with 316L diaphragm and integral filtration.

The Liquid Air 2123311-346 Stainless Steel Compressed Air Regulator is engineered for precise primary pressure control of non-corrosive, high-purity, and liquefied gases (up to grade 4.5). Designed for consistent pressure delivery despite supply fluctuations, it operates with a maximum inlet pressure of 4000 PSIG.

Key technical features include:

  • 316L stainless steel diaphragm minimizes inboard diffusion, enhancing gas purity critical in molecular diagnostics and bioprocessing environments.
  • CAPSULE seat design provides integral 360° multi-stage filtration, ensuring contaminant-free gas flow suitable for biotechnology and clinical diagnostics requiring ultra-clean gas streams.
  • Built-in standard relief valve safeguards the diaphragm and pressure gauges from overpressure damage, preserving regulator longevity in demanding industrial or laboratory settings.
  • High flow capacity supports multiple user locations, ideal for biomanufacturing pipelines where simultaneous gas delivery is essential.
  • Verified leak integrity via spectrometric helium leak detection confirms suitability for trace gas applications in synthetic biology and sensitive analytical workflows.

This compressed air regulator is essential in biomedical engineering, live-cell imaging, and other research fields emphasizing contamination control and precise gas delivery. Its robust stainless steel construction and advanced filtration make it a reliable component widely used in gene editing laboratories and biotechnology research facilities requiring stable gas pressure for critical experiments.

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.
