Concoa Purity Plus Gas Regulator Two Stage CGA 580 Inlet

CONCOA 2123351-84-580 Purity Plus Gas Regulator – Dual-Stage, CGA 580

The CONCOA 2123351-84-580 is an advanced dual-stage pressure regulator designed for the ultra-stable delivery of high-purity inert gases. Machined from high-grade brass barstock, the 212 Series minimizes internal surface area and outgassing, ensuring that analytical carrier gases reach their destination without absorbing atmospheric contaminants. The dual-stage pressure reduction mechanism completely eliminates the "supply-pressure effect," preventing the delivery pressure from drifting upward as the cylinder empties. Pre-configured with a CGA 580 inlet connection, this regulator is the industry standard for securing Nitrogen, Argon, and Helium cylinders. Featuring a 4000 PSIG inlet gauge, a 200 PSIG outlet gauge, and a precision 1/4-inch MPT needle valve for fine flow metering, it provides an all-in-one solution for safely interfacing high-pressure tanks with delicate downstream instrumentation.

Technical Performance and Design

• Dual-Stage Precision: Two independent pressure reduction chambers work in tandem to guarantee a perfectly flat pressure curve, ensuring consistent gas flow to critical instruments without the need for constant manual readjustment.

• CGA 580 Inlet Connection: Utilizes the standard bullet-nose and right-hand male thread required for inert gases, providing a secure, metal-to-metal seal that safely manages cylinder pressures up to 3000+ PSIG.

• Brass Barstock Construction: The dense, non-porous brass body provides superior leak integrity and protects against ambient contamination, a critical requirement for high-purity gas chromatography (GC) or mass spectrometry (MS) carrier gases.

• Integrated Needle Valve: The 1/4" MPT outlet assembly features a built-in metering valve, allowing the operator to shut off or finely tune the outgoing gas flow directly at the cylinder head.

Key Benefits & Applications

• Analytical Instrumentation: The perfect high-purity regulator for supplying inert carrier gases to Gas Chromatographs (GC), ICP-MS systems, and sensitive environmental analyzers.

• Set-and-Forget Reliability: The dual-stage design allows technicians to set the delivery pressure once; the regulator will hold that exact pressure from a full tank all the way down to empty.

• Purging & Blanketing: Highly effective for creating stable inert environments in chemical reactors, Schlenk lines, and semiconductor manufacturing equipment.

• Safe Operations: Heavy-duty construction and easy-to-read, dual-scale dials protect laboratory staff from the severe hazards of uncontrolled high-pressure gas release.
