223-0010 - Miller Smith 223 Series Silverline High Purity Two-Stage Regulator CGA 590

Precision Control for Analytical Applications

The Miller Smith 223-00-10 Silverline High Purity Analytical Two-Stage Regulator is engineered for environments where gas purity and pressure stability are non-negotiable. Designed specifically for the control of carrier gases and calibration mixtures, this regulator is a staple in laboratories utilizing gas chromatography techniques such as thermal conductivity, flame ionization, and electron capture. The core of its performance lies in its two-stage design, which ensures that delivery pressure remains constant even as the cylinder pressure drops from full to nearly empty. This feature is critical for long-duration analytical runs where pressure fluctuation could compromise data integrity.

Advanced Construction and Materials

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to provide superior protection against environmental corrosion and wear. Inside, a stainless steel diaphragm offers precise response to pressure changes while maintaining the integrity of the gas stream. Unlike rubber or neoprene diaphragms, stainless steel does not off-gas or absorb contaminants, making it ideal for high-purity applications. Additionally, the regulator features a filtered seat which prevents particulate contamination from entering the sealing area, thereby extending the service life of the unit and ensuring the delivered gas remains pure.

Safety and Versatility

Safety is paramount in high-pressure gas handling. The 223-00-10 includes a built-in capturable preset safety relief valve that protects downstream equipment and the regulator itself from over-pressurization. The unit is also designed to withstand vacuums generated during purging operations, a common procedure in switching out high-purity cylinders. With a delivery range of up to 150 PSIG and a CGA 590 inlet connection, this regulator is versatile enough for a variety of non-corrosive specialty gas mixtures. The large 2-1/2 inch single scale gauges make monitoring cylinder and delivery pressure effortless, ensuring operators can maintain precise control at all times.
