220-0000 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator 15 PSI

High Purity Precision for Analytical Applications

The Miller Smith 220-00-00 Silverline High Purity Analytical Two Stage Regulator is a premium solution designed for the rigorous demands of laboratory and analytical environments. When working with carrier gases or calibration mixtures for gas chromatography, maintaining gas purity and pressure stability is non-negotiable. This regulator addresses these needs with a robust two-stage design that takes high-pressure cylinder gas and steps it down to a precise, consistent working pressure of up to 15 PSI. Unlike single-stage regulators that may see outlet pressure rise as the cylinder empties, the 220 Series maintains a flat delivery curve, ensuring your sensitive instruments receive a steady flow from full cylinder to empty.

Advanced Contamination Control

One of the standout features of the 220-00-00 is its stainless steel diaphragm. In high-purity applications, standard elastomeric diaphragms can release trace contaminants or absorb gases, compromising analytical results. The stainless steel construction prevents this off-gassing and absorption, preserving the integrity of the gas stream. Additionally, the regulator features a filtered seat which not only aids in maintaining purity but also protects the internal seating mechanism from particulate damage, significantly extending the service life of the unit.

Designed for the Lab

The regulator is built with a plated body, bonnet, and gauges, offering superior resistance to environmental corrosion and maintaining a clean, professional appearance suitable for laboratory settings. The large 2-1/2 inch gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. With 1/4" FNPT inlet and outlet ports, this unit offers versatility for various piping configurations or custom connection requirements. Whether used for thermal conductivity, flame ionization, or electron capture detectors, the Miller Smith 220-00-00 delivers the reliability and purity required for critical analytical work.
