The Miller Smith 220-40-09 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 component for applications requiring absolute stability and cleanliness, such as gas chromatography (thermal conductivity, flame ionization, flame photometry, and electron capture). The core of its performance lies in its two-stage design, which provides precise control from a full cylinder down to nearly empty, eliminating the delivery pressure fluctuations often seen in single-stage counterparts as the inlet pressure decays.
Maintaining the integrity of the gas stream is paramount in analytical work. The 220-40-09 features a stainless steel diaphragm that not only offers precise response to pressure changes but also prevents the off-gassing or absorption issues associated with elastomeric diaphragms. This ensures that the gas delivered to your instruments remains as pure as the source. Additionally, the regulator includes a filtered seat, which adds another layer of protection by trapping particulates that could otherwise damage the seat or contaminate the downstream process, thereby extending the service life of the unit.
While designed for delicate analytical tasks, the Silverline 220 Series is built to last. The body, bonnet, and gauges are fully plated, providing superior protection against corrosion and wear in laboratory settings. The regulator is constructed from rugged brass bar stock, ensuring durability without compromising on precision. It is also capable of withstanding vacuums generated during purging operations, a critical feature for maintaining system purity during cylinder changeovers. Safety is integrated into the design with a built-in capturable preset safety relief valve that protects components from over-pressurization.
