213-0308 - Miller Smith 210 Silverline High Purity Oxygen Regulator CGA 540

Precision Gas Control for Analytical Applications

The Miller Smith 213-03-08 Silverline High Purity Analytical Single Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for non-corrosive specialty gases, this regulator ensures that the integrity of your gas stream remains uncompromised from the cylinder to your instrument. The core of its performance lies in the stainless steel diaphragm, which provides not only precise pressure control but also maintains a metal-to-metal seal that eliminates the outgassing associated with elastomeric diaphragms. This feature is critical for applications such as gas chromatography, automotive emissions testing, and biological research where even trace contamination can skew results.

Superior Contamination Resistance

In high-purity applications, atmospheric contamination is a constant threat. The 210 Silverline series addresses this with a design that is highly resistant to inboard diffusion. The regulator is constructed from rugged brass bar stock, which is then fully plated—including the body, bonnet, and gauges—to offer superior protection against environmental corrosion and to maintain a clean aesthetic suitable for laboratory settings. Furthermore, the unit is capable of withstanding vacuums generated during purging operations, ensuring that lines can be effectively cleared without damaging the internal components of the regulator.

Reliable and Safe Operation

Safety and longevity are paramount in the design of the 213-03-08. It features a filtered seat that traps particulate matter before it can damage the seating surface, significantly extending the service life of the regulator and ensuring consistent performance over time. A built-in capturable preset safety relief valve provides an added layer of protection against over-pressurization. The large, 2-1/2 inch single-scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. With a delivery range of 0-150 PSI and a CGA 540 connection, this regulator is the ideal choice for high-purity oxygen service in analytical setups.
