223-0006 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 223-00-06 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 tool for applications requiring absolute consistency, such as gas chromatography (thermal conductivity, flame ionization, flame photometry, and electron capture). The 220 Silverline Series distinguishes itself with a robust two-stage design, which allows for precise control from full to nearly empty cylinders, eliminating the delivery pressure decay often seen in single-stage alternatives.

At the heart of this regulator is a stainless steel diaphragm, chosen for its ability to provide precise pressure control while maintaining the integrity of the gas stream. This feature is critical for preventing contamination in sensitive analytical workflows. The regulator also features a filtered seat that adds an extra layer of gas stream purity and significantly extends the service life of the unit by trapping particulates. Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to offer superior protection against environmental corrosion and wear.

Safety and ease of use are paramount in the 223-00-06 design. It includes a built-in capturable preset safety relief valve to protect components from over-pressurization. The large 2-1/2 inch single-scale gauges are easy to read, ensuring operators can monitor cylinder and delivery pressure at a glance. Furthermore, the regulator is capable of withstanding vacuums generated during purging operations, making it highly versatile for complex gas delivery setups. With a delivery range of 0-200 PSIG and a CGA 350 connection, it is perfectly suited for hydrogen, methane, and other compatible specialty gases.
