Airgas Model 2172C3502 Stainless Steel Ultra-High Purity Two Stage Regulator With CGA-350 ConnectionTied diaphragm regulators resist attack from strong acid forming gases and facilitate safe handling of corrosive, toxic and reactive gases with an inlet pressure of up to 3000 psig (207 bar). They are especially useful in semiconductor manufacturing applications. Two stage design is recommended for use where constant delivery pressure is desired.

Also for chromatography processes where the gas cannot be compromised by any interaction
