220-2005 - Miller Smith 220 Series Silverline Two-Stage High Purity Regulator CGA 346

Precision Control for Analytical Applications

The Miller Smith 220-20-05 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 pure gases and mixtures, this regulator is an essential tool for professionals utilizing gas chromatography techniques such as thermal conductivity, flame ionization, flame photometry, and electron capture. Its robust construction and precision engineering ensure that your critical processes receive a stable and contaminant-free gas supply.

Uncompromised Purity and Stability

At the heart of the 220 Series is a stainless steel diaphragm that provides precise control over outlet pressure while maintaining the integrity of the gas stream. Unlike standard rubber diaphragms, stainless steel prevents off-gassing and contamination, which is crucial for analytical accuracy. The regulator also features a filtered seat that traps particulates, further enhancing gas stream purity and extending the service life of the unit. The two-stage design is particularly beneficial for applications requiring constant delivery pressures; it automatically compensates for the drop in cylinder pressure as the tank empties, ensuring a steady flow from full to nearly empty.

Durable and Safe Construction

Built from rugged brass bar stock, the body, bonnet, and gauges are fully plated to offer superior protection against corrosion and wear in laboratory settings. The large 2-1/2 inch single scale gauges are easy to read, allowing for quick monitoring of tank and delivery pressures. Safety is paramount in high-pressure gas handling, which is why this model includes a built-in capturable preset safety relief valve. Additionally, the regulator is designed to withstand vacuums generated during purging operations, adding versatility to its operational capabilities. With a delivery range of 0-15 PSI and a CGA 346 connection, this regulator is the definitive choice for high-purity air and analytical gas regulation.
