OVERVIEW

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.

FAQ

A two-stage regulator reduces the cylinder pressure in two steps, which provides a constant delivery pressure regardless of the decreasing pressure in the supply cylinder. This eliminates the need for frequent adjustments as the tank empties.

The CGA 580 fitting is the standard connection for inert gases such as Argon, Nitrogen, and Helium. It is not compatible with flammable gases or oxygen.

Stainless steel diaphragms are non-reactive and do not absorb or off-gas impurities like rubber diaphragms can. This is essential for maintaining the purity of analytical gases.

Yes, the Miller Smith 220 series regulators are designed to withstand vacuums generated during purging operations, which is critical for removing contaminants from the system lines.

This specific model (220-42-09) is designed for low-pressure applications with a delivery range of approximately 0-15 PSIG.

No, this regulator is recommended for high purity, non-corrosive pure gases and mixtures. Corrosive gases require regulators made from specific materials like Monel or Hastelloy.

The regulator is rated for a maximum inlet pressure of 3500 PSI, making it safe for use with standard high-pressure cylinders.

Yes, it includes two large 2-1/2 inch single scale gauges: one for monitoring the cylinder pressure and one for the delivery pressure.
