222-0306 - Miller Smith Silverline 220 Series Two-Stage High Purity Regulator, CGA 350, 0-100 PSI

Precision Analytical Control with Miller Smith Silverline

The Miller Smith 222-03-06 Silverline High Purity Analytical Two-Stage Regulator is engineered specifically for the demanding requirements of laboratory and analytical applications. Part of the renowned 220 Silverline Series, this regulator is designed to manage high purity, non-corrosive pure gases and mixtures with exceptional precision. It is an ideal choice for critical applications such as gas chromatography, including thermal conductivity, flame ionization, flame photometry, and electron capture processes where gas stream purity is paramount.

Advanced Two-Stage Design

Analytical work requires stability. The two-stage design of the 222-03-06 ensures that delivery pressure remains constant, even as the cylinder pressure drops from full to nearly empty. This eliminates the need for frequent manual adjustments and ensures that sensitive instruments receive a steady flow of gas, preventing baseline drift and ensuring accurate calibration results. The regulator features a stainless steel diaphragm which provides precise control of pressure while maintaining the integrity of the gas stream, preventing off-gassing or contamination that can occur with elastomeric diaphragms.

Construction and Durability

Built from rugged brass bar stock, the body, bonnet, and gauges are fully chrome-plated. This not only gives the regulator a professional laboratory aesthetic but also provides superior protection against corrosion and wear. The unit includes a filtered seat to trap particulates, further enhancing gas purity and extending the service life of the internal components. Large, easy-to-read 2-1/2 inch single scale gauges allow operators to monitor cylinder and delivery pressure at a glance. Safety is also a priority, with a built-in capturable preset safety relief valve that protects components from over-pressurization while allowing for safe venting if necessary.

Application Suitability

With a CGA 350 inlet connection, this regulator is compatible with standard cylinders for gases such as Hydrogen and Methane mixtures often used in analytical settings. The 0-100 PSIG delivery range offers versatile control for various instrument requirements. Whether used for carrier gases or calibration mixtures, the Miller Smith 222-03-06 delivers the reliability and purity required for high-level scientific work.
