Restek's 21669 Ultra High Purity Air Regulator is designed for precise control of air flow in sensitive gas chromatography (GC) applications, particularly those utilizing Mass Spectrometry (MS), PhotoIonization Detection (PID), Flame Ionization Detection (FID), or Electron Capture Detection (ECD). This dual-stage regulator features a chrome-plated brass body for reduced internal volume compared to stainless steel counterparts, while still offering excellent durability and corrosion resistance.

The regulator boasts a 316L stainless steel diaphragm valve for leak-proof shutoff and a maximum inlet pressure rating of 3000 psig (20,684 kPa). The easy-to-read gauges display both inlet pressure (0 to 4000 psig) and outlet pressure (0 to 200 psig), allowing for precise control of gas flow. Additionally, the 0.25-inch NPTF outlet valve ensures compatibility with various GC setups.
