Airgas Two Stage Brass 0-50 psi Analytical Cylinder Regulator with Needle Outlet CGA-350Item Details This analytical series of high purity brass, two stage regulators is recommended for non corrosive analyticaland process applications where precise pressure control isrequired. This series is ideally suited for chromatographiccarrier gas applications including FID, TCD, ECD, HID, andnon corrosive gas mixtures for analytical instrumentation. These units feature stainless steel diaphragms and bar stockbodies with low internal volume and

They are also equipped with a reverse-flow check valve to prevent backflow of gas into the regulator on the outlet

This two-stage regulator is recommended for use with non-corrosive gases in applications where an ultra-low delivery pressure is required

Round construction and elevated bottom encourage circulation of air around the can to disperse heat and reduce moisture buildup and rusting

The needle valve model hasthe valve built into the regulator body reducing the gas path

Rated to 3

The regulator body is machined from brass bar stock
