223-4008 - Miller Smith Silverline 220 Series High Purity Oxygen Regulator CGA 540

Precision Control for Analytical Applications

The Miller Smith 223-40-08 Silverline High Purity Analytical Two Stage Regulator is engineered for environments where gas purity and pressure stability are paramount. Designed specifically for high purity, non-corrosive pure gases and mixtures, this regulator is an essential component for laboratory setups, including gas chromatography applications such as thermal conductivity, flame ionization, flame photometry, and electron capture. The unit features a stainless steel diaphragm that ensures precise control of pressure while maintaining the integrity of the gas stream, preventing contamination that could compromise sensitive analytical results.

One of the standout features of the 220 Silverline Series is its two-stage design. This configuration allows for precise control from full to nearly empty cylinders, providing a constant delivery pressure regardless of fluctuations in cylinder pressure. This is critical in analytical work where pressure drift can lead to inaccurate data. The regulator is also built to withstand vacuums generated during purging operations, adding to its versatility in complex gas delivery systems. The filtered seat further enhances gas stream purity and extends the service life of the regulator by trapping particulates before they reach the seating area.

Durability meets precision with a rugged brass bar stock construction that is fully plated—body, bonnet, and gauges—offering superior protection against corrosion and wear. The large 2-1/2 inch single scale gauges are easy to read, ensuring operators can monitor system status at a glance. Safety is integrated into the design with a built-in capturable preset safety relief valve that protects components from over-pressurization. With a delivery range of 0-150 PSIG and a CGA 540 connection, this regulator is the professional choice for high-purity oxygen service and compatible analytical gases.
