223-0008 - Miller Smith Silverline 220 Series High Purity Oxygen Regulator CGA 540

Precision Control for Analytical Applications

The Miller Smith 223-00-08 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 gas applications, this regulator excels in scenarios where maintaining gas integrity and constant delivery pressure is critical. The unit features a stainless steel diaphragm, which is essential for preventing the off-gassing and elastomeric contamination often associated with rubber diaphragms. This makes it an ideal choice for sensitive instrumentation such as gas chromatographs.

Advanced Two-Stage Design

Stability is paramount in analytical work. The 223-00-08 utilizes a two-stage regulation mechanism. The first stage reduces the high-pressure input from the cylinder to an intermediate pressure, while the second stage reduces it further to the precise working pressure required by your equipment. This configuration ensures that the delivery pressure remains constant even as the cylinder pressure drops from full to nearly empty, eliminating the need for frequent manual adjustments and ensuring the repeatability of your analytical results.

Construction and Safety

Durability meets purity in the Silverline series. The regulator is constructed from rugged brass bar stock, which is then plated—along with the bonnet and gauges—to provide superior protection against environmental corrosion and to maintain a clean aesthetic suitable for laboratory settings. A filtered seat is integrated into the design to trap particulates, further enhancing gas stream purity and extending the service life of the seat assembly. For safety, the unit includes a built-in capturable preset safety relief valve that protects downstream components from over-pressurization. Furthermore, the design is robust enough to withstand vacuums generated during purging operations, a common procedure in high-purity gas handling.
