222-0005 - Miller Smith Silverline 220 Series Two-Stage High Purity Air Regulator, CGA 346, 0-100 PSIG

Precision Control for Analytical Applications

The Miller Smith 222-00-05 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for high-purity air applications utilizing a CGA 346 connection, this regulator ensures that your sensitive instrumentation receives a consistent and contaminant-free gas flow. The core of its performance lies in the stainless steel diaphragm, which provides precise pressure control while eliminating the risk of elastomeric off-gassing that can compromise gas purity in sensitive workflows.

Two-Stage Stability

In analytical processes such as gas chromatography, maintaining a constant delivery pressure is non-negotiable. Single-stage regulators can suffer from "decay," where outlet pressure rises as the cylinder pressure falls. The Miller Smith 222-00-05 utilizes a two-stage design that steps down pressure in two increments. This configuration guarantees a steady 0-100 PSIG delivery pressure from a full cylinder down to a nearly empty one, providing the stability required for thermal conductivity, flame ionization, and other detector systems.

Rugged and Clean Construction

While built for precision, the Silverline series does not compromise on durability. The regulator features a rugged brass bar stock construction that is fully plated—including the body, bonnet, and gauges—to offer superior protection against corrosion and to maintain a clean aesthetic suitable for laboratory settings. The filtered seat prevents particulate contamination from entering the gas stream, further extending the service life of the regulator and protecting downstream equipment. Additionally, the unit is designed to withstand vacuums generated during purging operations, ensuring versatility in complex gas management setups.
