Airgas Two Stage Brass 0-25 psi Analytical Cylinder Regulator With Needle Outlet CGA-346This 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 minimal dead

The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10–8 ccs helium

Optional 15 Ra electropolished with faceseal

easy reading

Product Type: Traffic Barrel Base

Attractive nickel-plating looks good and lasts for years of service

A PCTFE seat provides positive closure and is compatible with a wide range of mildly corrosive or corrosive gases

These regulators are typically used in conjunction with other high-pressure regulators or on house-line systems that limit inlet pressure to 250 psig (except on model N570K the inlet pressure limit is 10 psig)

convoluted Hastelloy® diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal

These regulators are nickel-plated to maintain their appearance through years of service

Environmental testing processes where the gases would have formaldehyde and HF would also benefit from using these products

This series is ideally suited for high-pressure testing

stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal
