223-0106 - Miller Smith Silverline 220 Series Analytical Two-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 223-01-06 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 pure gases and mixtures, this regulator is an essential component for applications where gas stream integrity and constant delivery pressure are paramount. The Silverline 220 Series represents a convergence of durability and precision, utilizing a rugged brass bar stock construction that is fully plated to ensure superior protection against environmental factors while maintaining a clean aesthetic suitable for laboratory settings.

At the heart of this regulator is a stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb contaminants, the stainless steel construction ensures that the purity of the gas stream remains uncompromised from the cylinder to the instrument. This feature is particularly critical in gas chromatography applications, such as thermal conductivity, flame ionization, flame photometry, and electron capture, where even trace impurities can skew results. The diaphragm also provides precise control of pressure, allowing for minute adjustments necessary for sensitive analytical equipment.

The two-stage design of the 223-01-06 is a key advantage for long-duration processes. As a gas cylinder empties, the inlet pressure drops, which can cause delivery pressure to fluctuate in single-stage regulators. This two-stage model compensates for these changes, delivering a steady, unwavering flow from a full cylinder down to nearly empty. This reliability eliminates the need for constant monitoring and adjustment by technicians. Additionally, the unit features a filtered seat to trap particulates, extending the service life of the regulator, and a built-in capturable preset safety relief valve to protect downstream components from over-pressurization. With large 2-1/2 inch easy-to-read gauges and a CGA 350 connection, this regulator is the professional's choice for hydrogen and compatible specialty gas service.
