222-0008 - Miller Smith Silverline 220 Series Two-Stage High Purity Oxygen Regulator, 0-100 PSI, CGA 540

Precision Control for Analytical Applications

The Miller Smith 222-00-08 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 ensures that your sensitive instrumentation receives a stable and contaminant-free gas supply. The core of its performance lies in its two-stage design, which reduces cylinder pressure in two steps. This mechanism guarantees a constant delivery pressure of 0-100 PSI, regardless of fluctuations in the supply cylinder pressure, a critical feature for long-duration chromatography runs or calibration processes where baseline stability is paramount.

Constructed with a focus on purity, the 220 Silverline series features a stainless steel diaphragm. Unlike elastomeric diaphragms, stainless steel prevents off-gassing and absorption, ensuring the integrity of the gas stream is maintained from the cylinder to your instrument. The regulator also incorporates a filtered seat, which not only adds another layer of protection for gas purity but also extends the service life of the seat by preventing particulate damage. The body, bonnet, and gauges are fully plated, providing a clean, professional appearance and superior protection against environmental factors.

Safety and usability are also key components of the 222-00-08. It includes a built-in capturable preset safety relief valve to protect downstream components from over-pressurization. The large, 2-1/2 inch single-scale gauges are easy to read, allowing for quick checks of tank and delivery pressure. Furthermore, the design is robust enough to withstand vacuums generated during purging operations, making it a versatile choice for complex gas delivery systems.
