221-0209 - Miller Smith Silverline 220 Series Analytical Two-Stage Regulator, CGA 580, 0-60 PSI

Precision Control for Analytical Applications

The Miller Smith 221-02-09 Silverline High Purity Analytical Two Stage Regulator is engineered specifically for the rigorous demands of laboratory and analytical environments. Designed to manage non-corrosive pure gases and mixtures, this regulator is an essential component for applications requiring absolute stability and purity, such as gas chromatography, thermal conductivity, flame ionization, and flame photometry. The core of its performance lies in its two-stage design, which allows for precise control from full to nearly empty cylinders. This ensures that delivery pressure remains constant regardless of fluctuations in cylinder pressure, a critical factor in maintaining the integrity of sensitive analytical results.

Constructed with a stainless steel diaphragm, the 221-02-09 eliminates the risk of outgassing or absorption often associated with elastomeric diaphragms, thereby preserving the purity of the gas stream. The filtered seat further enhances this purity while extending the service life of the regulator by preventing particulate damage. The unit is built from rugged brass bar stock and finished with a plated body and bonnet, offering superior protection against environmental factors. Additionally, the regulator is designed to withstand vacuums generated during purging operations, making it highly versatile for complex gas delivery systems. With a delivery range of 0-60 PSIG and a CGA 580 inlet, it is perfectly suited for inert carrier gases and calibration mixtures.
