Airgas Model N245E580 Brass High Purity Single Stage Pressure Regulator With 1/4” FNPT Connection And Non-Lubricated Check Valve regulator and the threaded-seat design allows

and the threaded-seat design allows for internal vacuum purging

This series is ideally suited for chromatographic carrier gas applications including FID

This creates consistencies in processes and extendscolumn life in GC applications

Because these regulators are not typically recommended for direct connection to cylinders

Airgas Model N245E580 Brass High Purity Single Stage Pressure Regulator With 1/4” FNPT Connection And Non-Lubricated Check Valve regulator and the threaded-seat design allowsThese brass, single stage, high purity regulators are recommended for non corrosive analytical and process applications where precise flow control is not critical. A specially designed, convoluted, stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. These regulators come with a CGA nipple that has a special
