220-0106 - Miller Smith Silverline 220 Series High Purity Analytical Regulator, CGA 350, 15 PSI

Precision Control for Analytical Applications

The Miller Smith 220-01-06 Silverline High Purity Analytical Two Stage Regulator is engineered specifically to meet the rigorous demands of laboratory and analytical environments. When precision is paramount, particularly in gas chromatography applications such as thermal conductivity, flame ionization, flame photometry, and electron capture, this regulator delivers unwavering performance. The core of its design features a high-grade stainless steel diaphragm, which is essential for maintaining the purity of the gas stream. Unlike elastomeric diaphragms that can off-gas or absorb contaminants, the stainless steel construction ensures that your carrier gases and calibration mixtures remain uncompromised from the cylinder to the instrument.

Stability is critical in analytical work, and the two-stage design of the 220 Series addresses this need by providing constant delivery pressure regardless of fluctuations in cylinder pressure. As a gas cylinder empties, the inlet pressure drops, which can cause single-stage regulators to exhibit a rise in outlet pressure. The Miller Smith 220-01-06 eliminates this variable, allowing researchers and technicians to focus on their results rather than monitoring their gas supply. The unit is also designed to withstand vacuums generated during purging operations, a common procedure in high-purity systems to remove atmospheric contaminants before introducing the process gas.

Durability meets cleanliness with the regulator's plated body, bonnet, and gauges. This plating not only provides an aesthetic, professional appearance suitable for laboratory settings but also offers superior protection against environmental corrosion. The filtered seat design further enhances reliability by trapping particulates that could damage the seating surface, thereby extending the service life of the regulator and maintaining the integrity of the gas flow. With a delivery range optimized for low-pressure applications (up to 15 PSI) and a CGA 350 connection suitable for hydrogen, methane, and other flammable gas mixtures, this regulator is the definitive choice for professionals requiring analytical-grade accuracy.
