201-0012 - Miller Smith Silverline 200 Series High Purity Line Regulator, 0-50 PSI

Precision Control for Analytical Applications

The Miller Smith 201-00-12 Silverline High Purity Analytical Line Regulator is engineered specifically for the rigorous demands of laboratory and research environments. Designed to manage low inlet pressures in pressure-sensitive applications, this regulator is a critical component for systems supplying gas chromatographs, mass spectrometers, and research sampling stations. Its primary function is to maintain the integrity of high-purity inert and non-corrosive gases, ensuring that the downstream analysis remains uncompromised by contaminants or pressure fluctuations.

Advanced Construction for Purity

At the heart of the 200 Series Silverline regulator is a stainless steel diaphragm. Unlike elastomeric diaphragms that can outgas or permit diffusion, stainless steel provides a non-permeable barrier that preserves the purity of the gas stream while offering precise control over delivery pressure. The regulator also features a filtered seat, which not only adds another layer of protection for gas stream purity but also significantly extends the service life of the unit by preventing particulate damage to the seating surface. The body, bonnet, and gauges are constructed from rugged brass bar stock and are fully plated, offering superior protection against environmental corrosion and wear.

Operational Versatility

This single-stage line regulator is rated for a maximum inlet pressure of 1200 PSI and delivers a consistent output range of 0-50 PSI (displayed on a 0-60 PSI scale). It is specifically designed to withstand vacuums generated during purging operations, a common procedure in high-purity gas handling to eliminate atmospheric contaminants before use. The unit comes equipped with a large, easy-to-read 2-1/2 inch single scale gauge and features a 1/4" MPT connection paired with a 1/8" stainless steel tube fitting, making it ready for integration into standard analytical tubing systems. The body is also tapped for rear panel mounting, facilitating organized and secure installation in instrument racks or laboratory benches.
