223-4102 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator, CGA 320, 0-150 PSI

Precision Control for Analytical Applications

The Miller Smith 223-41-02 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 tool for applications requiring absolute stability and cleanliness, such as gas chromatography. The unit features a CGA 320 inlet connection, making it suitable for high-purity Carbon Dioxide service.

At the core of the 220 Series Silverline is a stainless steel diaphragm. Unlike elastomeric diaphragms, stainless steel does not outgas or absorb contaminants, ensuring that the purity of your gas stream is maintained from the cylinder to your instrument. This feature allows for precise pressure control, critical for sensitive detectors like thermal conductivity, flame ionization, and electron capture devices. The regulator also incorporates a filtered seat, which further protects the internal components from particulate damage and extends the service life of the unit.

Reliability is paramount in analytical work. This regulator utilizes a two-stage design, which reduces the cylinder pressure in two steps. This configuration provides a constant delivery pressure of 0-150 PSI regardless of fluctuations in the supply cylinder pressure, allowing you to utilize the full content of the cylinder without constant adjustment. Constructed from rugged brass bar stock and finished with chrome plating, the body, bonnet, and gauges are protected against corrosion and wear, ensuring long-term durability in professional settings.
