222-4009 - Miller Smith Silverline 2-Stage High Purity Regulator CGA 580 0-100 PSI

Precision Control for Analytical Applications

The Miller Smith 222-40-09 Silverline High Purity Analytical Two Stage Regulator is engineered for professionals who demand exactitude in gas delivery. Designed specifically for high purity, non-corrosive gas applications, this regulator is a staple in laboratories and industrial settings requiring stable pressure control. The two-stage mechanism is the core of its performance, allowing for constant delivery pressure from full to nearly empty cylinders. This feature is critical for applications such as gas chromatography, where fluctuations in carrier gas pressure can compromise results.

Uncompromised Purity and Durability

Constructed with a rugged brass bar stock body, the regulator is fully plated—including the bonnet and gauges—to provide superior protection against environmental corrosion and wear. Inside, a stainless steel diaphragm ensures precise control of pressure while maintaining the purity of the gas stream, preventing the off-gassing or contamination often associated with rubber diaphragms. A filtered seat further enhances purity by trapping particulates, thereby extending the service life of the internal components. This unit is also capable of withstanding vacuums generated during purging operations, making it versatile for complex setups.

Safety and Ease of Use

Safety is paramount in high-pressure gas handling. The 222-40-09 features a built-in capturable preset safety relief valve that protects regulator components from over-pressurization. Operators can easily monitor system status via the large 2-1/2 inch single scale gauges, which provide clear readings of both cylinder and delivery pressures. With a delivery range of 0-100 PSI and a CGA 580 inlet, this regulator is optimized for inert gases like Nitrogen, Argon, and Helium, making it an essential tool for precision analytical work.
