223-0306 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 223-03-06 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 ensures that your critical applications receive a stable and contaminant-free gas flow. It is particularly well-suited for controlling carrier gases or calibration mixtures used in gas chromatography, including thermal conductivity, flame ionization, flame photometry, and electron capture processes.

Advanced Two-Stage Design

Stability is paramount in analytical work. The 223-03-06 features a robust two-stage design that provides precise control from full to nearly empty cylinders. Unlike single-stage regulators that may experience delivery pressure decay as the cylinder pressure drops, this unit maintains a constant delivery pressure regardless of fluctuations in the supply. This feature is essential for maintaining the integrity of sensitive analytical instruments and ensuring reproducible results in laboratory settings.

Superior Materials and Construction

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to offer superior protection against environmental factors and to maintain a clean aesthetic suitable for lab environments. The heart of the regulator is its stainless steel diaphragm, which provides precise pressure control while preventing the off-gassing or contamination often associated with elastomeric diaphragms. Additionally, a filtered seat is incorporated to add another layer of gas stream purity and to extend the service life of the regulator by preventing particulate damage.

Safety and Usability

Safety is integrated into the design with a built-in capturable preset safety relief valve, protecting the regulator components and downstream equipment from over-pressurization. The unit is also capable of withstanding vacuums generated during purging operations, making it versatile for various setup procedures. Large, easy-to-read 2-1/2 inch single scale gauges allow operators to monitor cylinder and delivery pressure at a glance. With a CGA 350 connection and a delivery range of 0-200 PSIG, this Miller Smith Silverline regulator is the professional choice for high-purity gas management.
