OVERVIEW

Precision Control for Analytical Excellence

When your work involves sensitive analytical instruments like gas chromatographs, thermal conductivity detectors, or flame ionization sensors, the quality of your gas delivery system is just as important as the gas itself. The Miller Smith 220-82-05 Silverline High Purity Regulator is built to ensure that your carrier gases and calibration mixtures are delivered with absolute consistency and purity. Unlike standard industrial regulators, the Silverline series is crafted to meet the exacting standards of laboratory environments where even minute fluctuations or contaminants can skew results.

Why Choose a Two-Stage Design?
In analytical applications, stability is key. As a gas cylinder empties, the pressure inside drops. A standard regulator might allow the outlet pressure to creep up or fluctuate in response. The Miller Smith 220 Series utilizes a two-stage design that compensates for these changes automatically, providing a rock-steady flow from a full cylinder down to nearly empty. This means you can run long-duration tests without constantly monitoring or adjusting your regulator settings.

Built for Purity
Contamination is the enemy of accurate analysis. That is why this regulator features a stainless steel diaphragm. Unlike rubber or neoprene, stainless steel does not absorb gases or release plasticizers, ensuring that the gas reaching your instrument is exactly what came out of the cylinder. The nickel-plated body not only looks professional on your lab bench but also provides superior protection against environmental corrosion. With large, easy-to-read 2-1/2 inch gauges and a filtered seat assembly, the Miller Smith 220-82-05 is the reliable choice for professionals who cannot afford to compromise on accuracy.

FAQ

A two-stage regulator provides constant delivery pressure regardless of fluctuations in the cylinder's inlet pressure. This is critical for analytical applications where stable flow is required as the cylinder empties.

CGA 346 is typically used for industrial air or specific high-purity gas mixtures. Always verify your cylinder's valve connection matches the regulator before use.

Stainless steel diaphragms are non-porous and do not off-gas or absorb contaminants, ensuring the high purity of the gas stream is maintained for sensitive analytical instruments.

Yes, the Miller Smith 220 Series is designed to withstand vacuums generated during purging operations without damaging the internal components.

This model has a delivery range of 30" Hg (vacuum) to 30 PSIG, allowing for precise low-pressure control.

No, the 220 Silverline series is recommended for high purity, non-corrosive pure gases and mixtures. For corrosive gases, a regulator with a stainless steel body would be required.

Yes, it features a built-in capturable preset safety relief valve to protect components from over-pressurization.

The regulator is rated for a maximum inlet pressure of 3500 PSIG.
