213-0005 - Miller Smith 210 Series Silverline High Purity Air Regulator CGA 346

Precision Control for Analytical Applications

The Miller Smith 213-00-05 Silverline High Purity Analytical Single Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for high purity, non-corrosive gases, this regulator ensures that the integrity of your gas stream is maintained from the cylinder to the instrument. The core of this performance lies in the stainless steel diaphragm, which provides precise pressure control and minimizes the hysteresis often found in elastomeric diaphragms. This feature is critical for applications such as gas chromatography, automotive emissions testing, and biological research where stable delivery pressure is paramount.

Contamination Resistance and Purity

In analytical settings, atmospheric contamination can compromise results. The 210 Silverline series addresses this with a design that is highly resistant to inboard diffusion. The regulator features a filtered seat that not only extends the service life of the component by trapping particulates but also adds a layer of assurance for gas stream purity. The materials of construction are carefully selected; while the body is rugged brass bar stock, it is fully plated, along with the bonnet and gauges, to prevent corrosion and ensure that the wetted surfaces do not introduce contaminants into the flow path. This makes it an excellent choice for chemical process plants where brass is acceptable but enhanced cleanliness is required.

Operational Versatility and Safety

The 213-00-05 is built to handle the realities of gas management. It is capable of withstanding vacuums generated during purging operations, a necessary procedure in high-purity setups to eliminate ambient air before gas flow begins. The unit comes equipped with a built-in capturable preset safety relief valve, adding a critical layer of safety for both the operator and downstream equipment. With a maximum inlet pressure of 3500 PSI and a delivery range suitable for up to 150 PSI applications, it covers a broad spectrum of analytical needs. The body is also tapped for rear panel mounting, facilitating clean and organized installation in gas cabinets or laboratory benches.

Clear Instrumentation

Monitoring pressure levels is effortless with the large 2-1/2 inch single scale gauges. These gauges are plated to match the body, offering superior protection against the environment while providing clear, easy-to-read metrics. The CGA 346 connection is specific to air service, ensuring compatibility with standard high-purity air cylinders used in industrial and laboratory settings. Whether you are setting up a new analytical station or upgrading existing equipment, the Miller Smith 213-00-05 delivers the reliability and purity required for precise scientific work.
