220-0109 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 580 15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-01-09 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for non-corrosive pure gases and mixtures, this regulator excels in applications requiring absolute consistency, such as gas chromatography (thermal conductivity, flame ionization, flame photometry, and electron capture). The two-stage design is critical for these sensitive operations, as it ensures that the delivery pressure remains constant even as the cylinder pressure drops from full to nearly empty, eliminating the need for constant manual adjustments.

Superior Materials and Construction

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to provide superior protection against corrosion and to maintain a clean, professional appearance suitable for lab settings. A key feature of the 220 Series is the stainless steel diaphragm, which offers precise control over pressure and prevents the off-gassing or contamination often associated with elastomeric diaphragms. This ensures that the high purity of your carrier gases or calibration mixtures is maintained from the cylinder to the instrument. Additionally, the regulator features a filtered seat that further enhances gas stream purity and extends the service life of the unit by preventing debris from damaging the seating surface.

Safety and Usability

Safety and ease of use are paramount in the design of the Miller Smith 220-01-09. It includes a built-in capturable preset safety relief valve that protects regulator components from over-pressurization. The unit is also robust enough to withstand vacuums generated during purging operations, a common requirement in high-purity gas handling. Operators will appreciate the large, 2-1/2 inch single-scale gauges that are easy to read at a glance. With a maximum inlet pressure of 3500 PSIG and a delivery range of 0-15 PSIG, this regulator is optimized for low-pressure applications where precision is non-negotiable.
