223-4108 - Miller Smith Silverline 220 Series High Purity Oxygen Regulator CGA 540

Precision Control for Analytical Applications

The Miller Smith 223-41-08 Silverline High Purity Analytical Two Stage Regulator is engineered for environments where gas purity and pressure stability are non-negotiable. Designed specifically for high-purity, non-corrosive pure gases and mixtures, this regulator is a staple in laboratories and industrial settings requiring exacting standards. Its primary application lies in the control of carrier gases or calibration mixtures used in gas chromatography, including thermal conductivity, flame ionization, flame photometry, and electron capture processes.

Advanced Two-Stage Design

Unlike single-stage counterparts, this two-stage regulator provides a constant delivery pressure regardless of fluctuations in the supply cylinder. As the cylinder pressure decays from full to nearly empty, the 223-41-08 maintains a steady output, eliminating the need for frequent manual adjustments. This feature is critical for long-duration analytical runs where pressure drift could compromise data integrity.

Superior Materials and Construction

Purity is maintained through a combination of high-quality materials. The regulator features a stainless steel diaphragm, which not only offers precise control over pressure but also ensures that the gas stream remains uncontaminated by rubber or elastomeric off-gassing. The seat is filtered to further enhance gas stream purity and extend the service life of the unit by preventing debris from damaging the sealing surface. The rugged brass bar stock body, bonnet, and gauges are fully plated, providing superior protection against corrosion and maintaining a clean, professional appearance suitable for lab environments.

Safety and Usability

Safety is paramount in high-pressure gas handling. This model includes a built-in capturable preset safety relief valve that protects regulator components from over-pressurization. Additionally, the design is robust enough to withstand vacuums generated during purging operations, a common procedure in high-purity gas delivery. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance.
