222-4110 - Miller Smith 220 Series Silverline Two-Stage High Purity Regulator CGA 590

Precision Control for Analytical Applications

The Miller Smith 222-41-10 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed for use with high purity, non-corrosive gases, this regulator features a CGA 590 connection, making it suitable for specific industrial air and specialty gas applications. The hallmark of the 220 Silverline series is its ability to maintain gas stream purity, a critical factor in analytical processes such as gas chromatography.

At the core of this regulator is a stainless steel diaphragm. Unlike rubber or elastomer diaphragms, stainless steel does not off-gas or absorb contaminants, ensuring that the gas delivered to your instruments remains as pure as the source. This feature allows for precise control of pressure, essential for sensitive equipment like thermal conductivity detectors, flame ionization detectors, and electron capture devices. The regulator is also designed to withstand vacuums, making it robust enough for purging operations without compromising internal components.

The two-stage design of the 222-41-10 is a significant advantage for applications requiring unwavering pressure stability. As a gas cylinder empties, the inlet pressure drops, which can cause outlet pressure to fluctuate in single-stage regulators. This two-stage model compensates for these changes, delivering a constant 0-100 PSI output from a full cylinder down to a nearly empty one. Housed in a chrome-plated brass body and bonnet, the regulator is not only durable but also resistant to corrosion and easy to keep clean in a lab setting. It comes equipped with a 1/8-inch tube fitting and a brass needle valve for fine flow adjustments.
