223-0002 - Miller Smith Silverline 220 Series High Purity CO2 Regulator, Two Stage, CGA 320

Precision Control for Analytical Applications

The Miller Smith 223-00-02 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 applications such as gas chromatography, including thermal conductivity, flame ionization, flame photometry, and electron capture processes. Its robust two-stage design ensures that delivery pressure remains constant, even as the cylinder pressure drops from full to nearly empty, providing the stability required for sensitive instrumentation.

Superior Construction and Purity

At the heart of the 223-00-02 is a stainless steel diaphragm that offers precise control over pressure while maintaining the integrity of the gas stream. This material choice eliminates the risk of elastomeric contamination, making it ideal for high-purity workflows. The regulator also features a filtered seat which not only adds another layer of gas stream purity but also significantly extends the service life of the unit by preventing debris from damaging the seating surface. The entire body, bonnet, and gauges are plated, offering superior protection against corrosion and wear in demanding environments.

Safety and Usability

Safety is paramount in high-pressure gas handling. This Miller Smith regulator includes a built-in capturable preset safety relief valve that protects components from over-pressurization. The unit is also designed to withstand vacuums generated during purging operations, adding to its versatility. Operators will appreciate the large, 2-1/2 inch single scale gauges that make monitoring cylinder and delivery pressure effortless. With a CGA 320 fitting tailored for Carbon Dioxide and a delivery range up to 150 PSI, this Silverline series regulator combines reliability, precision, and durability in one sophisticated package.
