220-4209 - Miller Smith 220 Series Silverline Analytical Regulator, CGA 580, 0-15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-42-09 Silverline High Purity Analytical Two Stage Regulator is engineered specifically for the rigorous demands of laboratory and analytical environments. When dealing with sensitive instrumentation such as gas chromatographs, thermal conductivity detectors, or flame ionization detectors, the stability and purity of the carrier gas are paramount. This regulator addresses these needs with a robust two-stage design that maintains a constant delivery pressure of 0-15 PSI, regardless of fluctuations in the supply cylinder pressure. This feature eliminates the "decay" or "droop" often seen in single-stage regulators as the tank empties, ensuring your baseline readings remain stable throughout the entire cylinder lifespan.

Material Integrity and Purity

Contamination is the enemy of analytical accuracy. The 220 Series Silverline regulator features a high-quality stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb impurities, stainless steel provides a non-reactive barrier that preserves the integrity of high-purity gases. This makes it an ideal choice for non-corrosive pure gases and calibration mixtures where parts-per-million or parts-per-billion accuracy is required. Furthermore, the seat is filtered to trap any particulate matter before it enters the regulation mechanism, extending the service life of the unit and adding another layer of protection for your downstream equipment.

Designed for the Lab Environment

Beyond its internal mechanics, the exterior of the Miller Smith 220-42-09 is finished with a plated body, bonnet, and gauges. This plating not only provides a clean, professional aesthetic suitable for laboratory settings but also offers superior protection against environmental corrosion. The large 2-1/2 inch single-scale gauges are designed for readability, allowing technicians to monitor cylinder and delivery pressure at a glance. The regulator is also engineered to withstand vacuums generated during purging operations, a critical capability for maintaining system purity during cylinder changeouts. With a maximum inlet pressure of 3500 PSI and a CGA 580 connection, this unit is compatible with standard high-pressure inert gas cylinders including Nitrogen, Argon, and Helium.
