212-0309 - Miller Smith Silverline 210 Series High Purity Regulator, CGA 580, 0-100 PSI

Precision Control for Analytical Applications

The Miller Smith 212-03-09 Silverline High Purity Analytical Single Stage Regulator is engineered specifically for applications demanding the utmost integrity in gas delivery. Part of the renowned 210 Silverline Series, this regulator is designed to control high purity, non-corrosive gases where precise maintenance of delivery pressure is required, although it is a single-stage design optimized for consistent inlet conditions. It is an ideal solution for instrument analysis, automotive emissions testing, biological laboratories, and chemical process plants where brass construction is acceptable but contamination must be minimized.

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to provide superior protection against environmental corrosion and to maintain a clean, professional appearance suitable for laboratory settings. A critical feature of this unit is the stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb impurities, the stainless steel interface ensures that the materials of construction do not contaminate the gas stream. This design is highly resistant to inboard diffusion of atmospheric contamination, preserving the purity of the analytical grade gases being regulated.

The 212-03-09 is equipped with a filtered seat mechanism which adds another layer of gas stream purity while simultaneously extending the service life of the regulator by preventing particulate damage. The unit features large, easy-to-read 2-1/2 inch single scale gauges, allowing operators to monitor cylinder and delivery pressure with accuracy. With a delivery range of 0-100 PSI and a CGA 580 inlet, it is perfectly suited for inert gases such as Nitrogen, Argon, and Helium. Furthermore, the regulator is designed to withstand vacuums generated during purging operations, a common requirement in high-purity gas handling protocols.
