220-8309 - Miller Smith Silverline 220 Series High Purity 2-Stage Regulator, CGA 580, 0-15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-83-09 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed for use with high-purity, non-corrosive gases such as Nitrogen, Argon, and Helium (CGA 580), this regulator ensures the integrity of your gas stream is maintained from the cylinder to the instrument. It is an ideal choice for gas chromatography applications, including thermal conductivity, flame ionization, flame photometry, and electron capture detectors, where stable pressure and gas purity are critical for accurate results.

Uncompromised Purity and Stability

At the core of the 220 Series is a stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb contaminants, stainless steel provides a non-reactive surface that preserves the purity of carrier gases and calibration mixtures. The regulator also features a filtered seat, which adds a layer of protection against particulate contamination, extending the service life of the seat and ensuring reliable performance over time. The two-stage design is essential for analytical work; it reduces the cylinder pressure in two steps, delivering a constant outlet pressure of 0-15 PSI regardless of fluctuations in the supply cylinder pressure. This means you can run your tests from a full cylinder down to nearly empty without constantly adjusting the regulator.

Durable and Functional Design

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to resist corrosion and maintain a clean appearance in laboratory settings. The large 2-1/2 inch single scale gauges are easy to read, allowing for quick verification of tank and delivery pressures. Safety is paramount, with a built-in capturable preset safety relief valve protecting downstream components from over-pressurization. Additionally, the design is robust enough to withstand vacuums generated during purging operations, ensuring versatility in various setup procedures.
