2230002 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator 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. As part of the renowned 220 Silverline Series, this regulator is specifically designed for applications where gas purity and pressure stability are non-negotiable. The unit features a CGA 320 inlet connection, making it suitable for high-purity Carbon Dioxide and compatible gas mixtures used in sensitive instrumentation.

Advanced Two-Stage Design

In analytical processes such as gas chromatography, fluctuations in carrier gas pressure can lead to shifting retention times and inaccurate data. The 223-00-02 utilizes a two-stage pressure reduction mechanism. The first stage reduces the high cylinder pressure to an intermediate level, while the second stage delivers the precise working pressure to your equipment. This configuration ensures that the delivery pressure remains constant (0-200 PSIG) even as the cylinder pressure drops from full to empty, eliminating the need for constant manual adjustments.

Material Integrity and Purity

Contamination is the enemy of high-purity applications. This regulator is constructed with a stainless steel diaphragm rather than a standard elastomeric one. Stainless steel eliminates the risk of off-gassing and absorption/desorption cycles that can introduce impurities into the gas stream. Furthermore, the regulator includes a filtered seat that not only protects the internal components from particulate damage but also enhances the overall purity of the gas stream. The body and bonnet are machined from rugged brass bar stock and fully plated to resist external corrosion and maintain a clean laboratory aesthetic.

Safety and Versatility

Safety is paramount when handling high-pressure cylinders. The Miller Smith 223-00-02 is equipped with an automatic reseating safety relief valve that protects downstream components from over-pressurization. Additionally, the design is robust enough to withstand vacuums generated during purging operations, a common procedure in high-purity gas handling to remove atmospheric contaminants before use. With large, easy-to-read 2-1/2 inch gauges, operators can monitor cylinder and delivery pressure at a glance.
