220-4107 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 510, 15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-41-07 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for high purity, non-corrosive pure gases and mixtures, this regulator is an essential component for applications requiring absolute stability and cleanliness, such as gas chromatography. Whether controlling carrier gases for thermal conductivity, flame ionization, flame photometry, or electron capture detectors, the 220 Series delivers the consistent performance necessary for accurate results.

Advanced Two-Stage Design

Stability is paramount in analytical settings. This regulator features a robust two-stage design that allows for precise control from a full cylinder down to nearly empty. Unlike single-stage regulators that may experience a rise in delivery pressure as the cylinder pressure decays, the 220-41-07 maintains a constant delivery pressure regardless of fluctuations in the supply. This ensures that sensitive instruments receive a steady flow, eliminating variables that could compromise data integrity.

Superior Materials and Construction

To maintain gas stream purity, the regulator is constructed with a stainless steel diaphragm. This material choice prevents the off-gassing and contamination often associated with elastomeric diaphragms, ensuring that the gas delivered is as pure as the source. The seat is filtered to further enhance purity and extend the service life of the unit by preventing particulate damage. The body, bonnet, and gauges are plated to provide superior protection against environmental factors and to maintain a clean, professional appearance suitable for laboratory settings.

Safety and Versatility

Safety is integrated into the design with a built-in capturable preset safety relief valve, protecting downstream components from over-pressurization. Additionally, the regulator is engineered to withstand vacuums generated during purging operations (up to 30" Hg), making it highly versatile for complex gas management systems. With a maximum inlet pressure of 3500 PSI and a precise delivery range of 0-15 PSI via a CGA 510 connection, this Miller Smith regulator is the reliable choice for critical analytical tasks.
