222-2008 - Miller Smith Silverline 220 Series High Purity Two-Stage Oxygen Regulator CGA 540

Precision Control for Analytical Applications

The Miller Smith 222-20-08 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for high purity, non-corrosive gases, this regulator is an essential component for applications requiring absolute stability and cleanliness, such as gas chromatography (thermal conductivity, flame ionization, flame photometry, and electron capture). Its robust construction and precision engineering ensure that carrier gases and calibration mixtures are delivered with unwavering accuracy.

Advanced Two-Stage Design

One of the critical challenges in analytical gas delivery is maintaining a constant outlet pressure as the supply cylinder depletes. The 222-20-08 utilizes a sophisticated two-stage design that compensates for fluctuations in inlet pressure. This means that from a full cylinder down to nearly empty, the delivery pressure remains stable at your set point (0-100 PSI), eliminating the need for constant manual adjustments and ensuring the integrity of sensitive analytical results.

Superior Materials and Construction

To maintain gas stream purity, the regulator features a stainless steel diaphragm which provides precise pressure control while preventing contamination that can occur with elastomeric diaphragms. The seat is filtered to further enhance gas purity and extend the service life of the unit by trapping particulates. The body, bonnet, and gauges are plated, offering superior protection against environmental corrosion and maintaining a clean, professional appearance suitable for laboratory settings.

Safety and Reliability

Safety is paramount in high-pressure gas handling. This Miller Smith regulator includes a built-in capturable preset safety relief valve that protects components from over-pressurization. Furthermore, the design is capable of withstanding vacuums generated during purging operations, a common procedure in high-purity systems. With a maximum inlet pressure rating of 3500 PSI and a CGA 540 connection, it is ready for standard high-pressure oxygen or high-purity gas cylinders.
