221-0106 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 350, 0-50 PSI

Precision Control for Analytical Applications

The Miller Smith 221-01-06 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of modern laboratory environments. Designed specifically for high-purity, non-corrosive gas applications, this regulator is a cornerstone component for professionals utilizing gas chromatography, including thermal conductivity, flame ionization, flame photometry, and electron capture detectors. When precision is paramount, the Silverline 220 Series delivers uncompromised performance.

Unwavering Pressure Stability

One of the primary challenges in managing specialty gases is maintaining a constant delivery pressure as the source cylinder is depleted. The 221-01-06 utilizes a sophisticated two-stage design that effectively eliminates the "supply pressure effect." By stepping down the pressure in two distinct stages, the regulator ensures that the output remains rock-steady from a full cylinder down to a nearly empty one. This feature is critical for calibration mixtures and carrier gases where even minor fluctuations can skew analytical results.

Constructed for Purity

Contamination is the enemy of analytical accuracy. This regulator features a stainless steel diaphragm, which not only provides precise control over pressure adjustments but also ensures that the gas stream remains pure, as stainless steel does not outgas or absorb contaminants like elastomeric diaphragms might. Additionally, the unit includes a filtered seat that traps particulates, further enhancing gas stream purity and extending the service life of the internal components.

Rugged and Reliable Design

While built for delicate tasks, the physical construction of the Miller Smith 221-01-06 is robust. It is machined from rugged brass bar stock and finished with a high-quality plating on the body, bonnet, and gauges. This plating offers superior protection against environmental corrosion and wear. The regulator is also designed to withstand vacuums generated during purging operations, a necessary procedure in high-purity setups to eliminate atmospheric contamination before gas flow begins. With large, easy-to-read 2-1/2 inch gauges and a built-in capturable safety relief valve, this regulator combines safety, durability, and precision in one package.
