222-0109 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 580

Precision Control for Analytical Applications

The Miller Smith 222-01-09 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 professionals requiring absolute consistency in gas delivery. The 220 Silverline Series stands out with its robust construction and precision components, making it the ideal choice for applications such as gas chromatography, thermal conductivity, flame ionization, and electron capture.

Advanced Two-Stage Design

One of the primary advantages of the 222-01-09 is its two-stage design. Unlike single-stage regulators that allow delivery pressure to rise as the cylinder pressure drops (the decaying cylinder effect), this two-stage unit maintains a constant delivery pressure from a full cylinder down to nearly empty. This feature is critical in analytical work where even minor pressure fluctuations can compromise test results or calibration standards. The regulator effectively steps down the pressure in two phases, ensuring a smooth and steady flow of carrier gases or calibration mixtures.

Superior Materials for Gas Purity

To maintain the integrity of high-purity gas streams, Miller Smith has equipped this regulator with a stainless steel diaphragm. This material choice prevents the off-gassing and contamination often associated with elastomeric diaphragms, ensuring that the gas reaching your instruments remains as pure as the source. Additionally, the regulator features a filtered seat which not only aids in maintaining stream purity but also protects the internal components from particulate damage, significantly extending the service life of the unit.

Durability and Safety

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to provide superior protection against corrosion and wear. The large 2-1/2 inch single scale gauges are easy to read, allowing for quick monitoring of tank and delivery pressures. Safety is paramount in high-pressure gas handling; therefore, this model includes a built-in capturable preset safety relief valve to protect downstream components from over-pressurization. Whether used for purging operations or steady-state analysis, the Miller Smith 222-01-09 delivers reliability you can trust.
