220-4109 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580, 0-15 PSIG

Precision Control for Analytical Applications

The Miller Smith 220-41-09 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 component for applications requiring absolute stability and cleanliness, such as gas chromatography, thermal conductivity, flame ionization, and electron capture.

Advanced Two-Stage Design

Analytical processes require a steady flow of gas at a constant pressure. Single-stage regulators can suffer from decaying delivery pressure as the supply cylinder empties. The 220 Series utilizes a two-stage design that compensates for fluctuations in cylinder pressure, delivering a precise and constant outlet pressure from a full cylinder down to a nearly empty one. This feature is critical for maintaining the integrity of calibration mixtures and carrier gases.

Superior Materials and Construction

To ensure gas stream purity, the regulator features a stainless steel diaphragm that provides precise control while preventing contamination often associated with elastomeric diaphragms. The seat is filtered to protect the internal mechanism from particulates, extending the service life of the unit. The body, bonnet, and gauges are plated to provide superior protection against corrosion and to maintain a clean, professional appearance suitable for laboratory settings. The rugged brass bar stock construction ensures durability without compromising on precision.

Safety and Usability

Safety is paramount in high-pressure gas handling. This model includes a built-in capturable preset safety relief valve that protects components from over-pressurization. Additionally, the regulator is designed to withstand vacuums generated during purging operations, making it versatile for various setup procedures. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. Equipped with a CGA 580 inlet, it is compatible with standard inert gas cylinders (Nitrogen, Argon, Helium).
