611-81090000 - Miller Smith High Purity Brass Regulator, Single Stage, 0-50 PSIG, CGA 580

Precision Gas Control for Analytical Applications

The Miller Smith 611-81090000 is a premium High Purity Brass Regulator designed to meet the rigorous demands of analytical instrumentation, laboratory research, and specialty gas delivery systems. Engineered with a focus on maintaining gas purity, this regulator features a high-quality brass barstock body that reduces the risk of contamination often associated with forged bodies. The internal construction typically utilizes a stainless steel diaphragm, a critical feature for high purity applications, as it prevents the off-gassing and absorption issues common with elastomeric diaphragms found in standard industrial regulators. This ensures that the gas reaching your instruments remains as pure as the source supply.

Single-Stage Stability

Operating as a single-stage device, this regulator takes high-pressure cylinder gas and reduces it to a working pressure in a single step. While two-stage regulators are often preferred for constant delivery pressure as the cylinder drains, this single-stage model offers a compact and cost-effective solution for applications where inlet pressure decay is monitored or where the highest level of delivery pressure constancy is not the primary critical factor compared to purity and material compatibility. It provides a stable delivery pressure range of 0-50 PSIG, making it exceptionally suitable for applications requiring low to medium pressure control with high precision.

Connectivity and Compatibility

Equipped with a CGA 580 inlet connection, this regulator is compatible with a wide range of inert gases, including Argon, Nitrogen, and Helium. This versatility makes it a staple in various industrial and scientific settings. The outlet is configured with a 1/8-inch tube fitting (likely stainless steel based on the SKU designation), facilitating secure and leak-free connections to standard laboratory tubing and instrumentation lines. Whether used for gas chromatography, carrier gas regulation, or precise purging applications, the Miller Smith 611-81090000 delivers the reliability and performance expected from a leader in gas equipment manufacturing.
