223-4010 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator CGA 590

Precision Control for Analytical Applications

The Miller Smith 223-40-10 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 gas applications, this regulator is an essential tool for professionals utilizing gas chromatography, thermal conductivity, flame ionization, and electron capture systems. Its robust construction and precision engineering ensure that your critical processes receive a stable and contaminant-free gas supply.

Uncompromised Purity and Stability

At the heart of the 223-40-10 is a stainless steel diaphragm. Unlike standard rubber or neoprene diaphragms, stainless steel does not off-gas or absorb impurities, ensuring that the high purity gas from your cylinder reaches your instrumentation without degradation. This feature is critical for analytical accuracy where even trace contaminants can skew results. Furthermore, the regulator features a filtered seat which traps microscopic particles, preventing seat damage and extending the operational life of the unit while maintaining stream purity.

Two-Stage Performance

Analytical work requires consistency. Single-stage regulators can suffer from "decaying inlet characteristic," where delivery pressure rises as the cylinder pressure falls. The Miller Smith 220 Series utilizes a two-stage design, effectively stepping down pressure in two intervals. This mechanism guarantees a constant delivery pressure of 0-150 PSIG throughout the entire life of the cylinder, from full to nearly empty. This stability eliminates the need for constant manual adjustments and ensures repeatable results in sensitive equipment.

Durability and Safety

The regulator body, bonnet, and gauges are fully chrome-plated, providing a clean, professional aesthetic that resists corrosion and wear in laboratory settings. It includes a built-in capturable preset safety relief valve to protect downstream equipment from over-pressurization. With a maximum inlet pressure rating of 3500 PSIG and a CGA 590 connection, this regulator is ready for heavy-duty service with compatible gases like Industrial Air and Sulfur Hexafluoride.
