Airgas Single Stage Brass 0-250 psi Analytical Cylinder Regulator CGA-350 Switchover This two-stage regulator is recommendedThis analytical series of high purity brass single stage regulators is recommended for non corrosive analytical and process applications where precise pressure control is not required. The check valve cylinder connection prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. Machined from brass bar stock, this regulator body has minimal
