222-4210 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 590

Precision Control for Analytical Applications

The Miller Smith 222-42-10 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 gases, this regulator is an essential tool for applications such as gas chromatography, where maintaining the integrity of carrier gases and calibration mixtures is paramount. The Silverline 220 Series distinguishes itself with a robust construction that prioritizes gas stream purity without compromising on durability.

Advanced Two-Stage Design

One of the standout features of the 222-42-10 is its true two-stage design. In analytical settings, pressure fluctuation can lead to inaccurate readings and compromised experiments. This regulator steps down cylinder pressure in two distinct stages, ensuring that the delivery pressure remains absolutely constant even as the supply cylinder empties. This "flat" delivery characteristic allows researchers and technicians to utilize the entire contents of a cylinder without constantly adjusting the regulator, providing peace of mind and operational efficiency.

Superior Materials for Purity

Contamination is the enemy of analytical work. To combat this, Miller Smith has equipped this regulator with a stainless steel diaphragm. Unlike rubber or neoprene diaphragms, stainless steel does not off-gas or absorb impurities, ensuring that the gas delivered to your instrumentation is as pure as the gas in the cylinder. Additionally, the regulator features a filtered seat that traps microscopic particles, protecting the internal mechanism and extending the service life of the unit. The body, bonnet, and gauges are fully plated, offering a clean, professional appearance and superior protection against environmental corrosion.

User-Friendly and Safe

Safety and ease of use are built into every aspect of the 222-42-10. It features large, 2-1/2 inch single-scale gauges that are easy to read at a glance. The unit also includes a built-in capturable preset safety relief valve, which protects the regulator components from over-pressurization. Capable of withstanding vacuums generated during purging operations, this regulator is as versatile as it is precise. With a delivery range of 0-100 PSIG and a CGA 590 connection, it is perfectly suited for handling industrial air, sulfur hexafluoride, and other compatible specialty gases.
