200-8112 - Miller Smith 200 Series Silverline High Purity Analytical Line Regulator, 0-30 PSIG

Precision Control for Analytical Applications

The Miller Smith 200-81-12 Silverline High Purity Analytical Line Regulator is a premium solution designed specifically for the rigorous demands of laboratory and research environments. Engineered as part of the renowned 200 Silverline Series, this single-stage line regulator excels in applications requiring low inlet pressure and high sensitivity, such as supplying gas chromatographs, mass spectrometers, and complex research sampling systems. Its architecture is optimized for high purity inert and non-corrosive gas delivery, ensuring that the integrity of your analytical results is never compromised by the gas supply equipment.

Advanced Material Construction

At the heart of the 200-81-12 is a stainless steel diaphragm. Unlike elastomeric diaphragms that can suffer from permeability and outgassing, the stainless steel construction provides a non-contaminating seal that preserves the purity of the gas stream. This feature is critical for analytical work where even trace impurities can skew data. The regulator body is machined from rugged brass bar stock and finished with plating on the body, bonnet, and gauges. This plating not only offers a professional aesthetic suitable for laboratory settings but also provides superior protection against environmental corrosion and wear.

Operational Excellence and Safety

This regulator is designed to handle the practical realities of gas system management. It is fully capable of withstanding vacuums generated during purging operations, a common procedure in high-purity systems to eliminate contaminants before use. The unit features a filtered seat which serves a dual purpose: it adds another layer of assurance for gas stream purity and significantly extends the service life of the regulator by preventing particulate damage to the seating surface. With a maximum inlet pressure rating of 1200 PSIG and a delivery range covering 30" HG vacuum to 30 PSIG, it offers versatile performance for various downstream applications. The large 2-1/2 inch single scale gauges allow for precise monitoring, and the body is tapped for rear panel mounting, facilitating clean and organized installation in instrument racks or benches.
