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

Precision Control for Analytical Applications

The Miller Smith 220-40-10 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. When precision is paramount, particularly in applications such as gas chromatography, thermal conductivity, and flame ionization, the stability of your gas delivery system can make or break your results. This regulator is part of the esteemed Silverline 220 Series, designed specifically for high purity, non-corrosive pure gases and mixtures.

Unwavering Pressure Stability

One of the primary challenges in gas delivery is the fluctuation of outlet pressure as the supply cylinder drains. The 220-40-10 utilizes a robust two-stage design to combat this issue. By reducing the pressure in two steps, the regulator maintains a constant delivery pressure of 0-15 PSIG regardless of the inlet pressure changes. This feature allows users to utilize the full content of their cylinders without constantly adjusting the regulator, ensuring seamless operation from a full tank down to a nearly empty one.

Superior Materials for Gas Purity

Contamination is the enemy of analytical accuracy. To ensure the integrity of your gas stream, this regulator features a stainless steel diaphragm. Unlike rubber or neoprene diaphragms that can off-gas or absorb impurities, stainless steel provides a non-reactive barrier that preserves the purity of the carrier gas. Additionally, the seat is filtered to prevent particulate contamination, extending the service life of the unit and protecting downstream instrumentation.

Built for Durability and Safety

The body, bonnet, and gauges are constructed from rugged brass bar stock and finished with a high-quality chrome plating. This not only gives the regulator a professional aesthetic but also provides superior protection against corrosion and wear. Safety is integrated into the design with a built-in capturable preset safety relief valve, which protects the regulator components from over-pressurization. Furthermore, the unit is engineered to withstand vacuums generated during purging operations, making it a versatile tool for complex gas setups.
