220-0009 - Miller Smith 220 Series High Purity Analytical Regulator, 0-15 PSI, CGA 580

Precision Control for Analytical Applications

The Miller Smith 220-00-09 Silverline High Purity Analytical Two Stage Regulator is engineered for the exacting demands of laboratory and analytical environments. Designed specifically for high purity, non-corrosive pure gases and mixtures, this regulator is an essential component for applications requiring absolute consistency and cleanliness, such as gas chromatography (thermal conductivity, flame ionization, flame photometry, and electron capture).

Advanced Two-Stage Design

Featuring a robust two-stage construction, the 220 Series regulator provides precise control from full to nearly empty cylinders. This design eliminates the fluctuation in delivery pressure often seen in single-stage regulators as the inlet pressure drops, ensuring a stable flow rate critical for sensitive calibration mixtures and carrier gases. The unit is rated for a maximum inlet pressure of 3500 PSIG and delivers a controlled output up to 15 PSIG.

Superior Materials and Construction

To maintain gas purity, the regulator utilizes a stainless steel diaphragm that prevents contamination and allows for precise pressure modulation. The seat is filtered to further enhance gas stream purity and extend the service life of the internal components. Constructed from rugged brass bar stock, the body, bonnet, and gauges are plated for superior protection against corrosion and wear. The regulator is also designed to withstand vacuums generated during purging operations, making it highly versatile for complex gas setups.

Safety and Usability

Safety is paramount in high-pressure gas handling. This model includes a built-in capturable preset safety relief valve that automatically reseats to protect components from over-pressurization. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. With a CGA 580 inlet, it is compatible with standard inert gas cylinders including Nitrogen, Argon, and Helium.
