222-2000 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, 0-100 PSI

Precision Control for Analytical Applications

The Miller Smith 222-20-00 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 gases, this regulator is an essential component for applications such as gas chromatography, thermal conductivity, flame ionization, and electron capture. Its robust construction and precise engineering ensure that sensitive instruments receive a stable and contaminant-free gas supply.

Superior Design and Materials

At the core of the 220 Series Silverline regulator is a stainless steel diaphragm. Unlike elastomeric diaphragms, stainless steel prevents off-gassing and absorption, maintaining the integrity of the gas stream. This feature is critical for analytical work where even trace impurities can compromise results. The regulator body, bonnet, and gauges are plated to provide superior protection against environmental corrosion, ensuring longevity and maintaining a clean appearance in laboratory settings. The unit is constructed from rugged brass bar stock, providing a solid foundation for high-pressure operations.

Unwavering Performance

The two-stage design of the 222-20-00 is its defining performance feature. By reducing pressure in two steps, the regulator maintains a constant delivery pressure of 0-100 PSIG regardless of fluctuations in the cylinder pressure. This means that as your gas cylinder empties, the output pressure remains rock-steady, eliminating the need for constant manual adjustments. Additionally, the regulator features a filtered seat to trap particulates, further enhancing gas purity and extending the life of the internal components. It is also designed to withstand vacuums generated during purging operations, making it highly versatile for complex gas management systems.
