223-0108 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 540

Precision Control for Analytical Applications

The Miller Smith 223-01-08 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for applications requiring absolute gas purity and unwavering pressure stability, this regulator is a critical component for gas chromatography, flame ionization, and thermal conductivity workflows. The Silverline 220 Series distinguishes itself with a construction that prioritizes both precision and cleanliness, ensuring that your carrier gases and calibration mixtures are delivered without contamination or fluctuation.

Advanced Two-Stage Design

In analytical settings, pressure stability is paramount. The 223-01-08 utilizes a sophisticated two-stage design that reduces cylinder pressure in two steps. This mechanism ensures that the delivery pressure remains constant throughout the entire life of the cylinder, from full to nearly empty. Unlike single-stage regulators that may experience a "decaying" outlet pressure as the inlet pressure drops, this Miller Smith regulator maintains a steady flow, eliminating the need for constant manual adjustments and ensuring the integrity of sensitive analytical results.

Superior Materials and Construction

To maintain high purity standards, the regulator features a stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or absorb contaminants, stainless steel provides a non-reactive barrier that preserves the chemical composition of the gas stream. The body, bonnet, and gauges are plated to resist corrosion and maintain a clean exterior suitable for laboratory environments. Furthermore, the seat is filtered to prevent particulate contamination, which not only protects the integrity of the gas stream but also significantly extends the service life of the regulator seat itself.

Safety and Versatility

Safety is integrated into the design with a built-in capturable preset safety relief valve, protecting downstream equipment from over-pressurization. The regulator is also robust enough to withstand vacuums generated during purging operations, a common procedure in high-purity gas handling. With a CGA 540 inlet, it is compatible with standard oxygen and compatible high-purity gas cylinders, delivering a pressure range of 0-150 PSIG suitable for a wide array of analytical instruments.
