Ultra-High-Purity Brass Line Regulator

By Restek
Ultra-High-Purity Brass Line Regulator

This single-stage regulator is used for ultra-high purity carrier gas for sensitive GC applications using MS, PID, HID, or ECD detection methods. Regulator is constructed of chrome-plated brass with a stainless steel regulator diaphragm to ensure ultra-high purity control of gases. Regulator features a check valve in the CGA fitting that keeps air out during cylinder change-out and a metal valve diaphragm to ensure leak-free shut-off. 150 psig maximum delivery pressure supports ECD operation. Use when you need to reduce line pressure by 20 psi of more.
