221-0306 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Precision Control for Analytical Applications

The Miller Smith 221-03-06 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 a critical component for applications where gas stream integrity and pressure stability are paramount. The Silverline 220 Series distinguishes itself with a robust yet refined construction, utilizing a stainless steel diaphragm that ensures precise control of pressure while eliminating the risk of elastomeric outgassing that could contaminate sensitive samples.

Unwavering Stability with Two-Stage Design

In analytical procedures such as gas chromatography, fluctuations in delivery pressure can lead to inconsistent baselines and inaccurate data. The 221-03-06 features a premium two-stage design, which functions by reducing the high cylinder pressure in two steps. This mechanical advantage allows the regulator to maintain a constant delivery pressure from the moment a full cylinder is opened until it is nearly empty. This "set it and forget it" reliability is essential for long-duration runs in thermal conductivity, flame ionization, and electron capture detection methods.

Engineered for Purity and Longevity

Every aspect of the Miller Smith 221-03-06 is built to preserve the purity of your gas supply. The unit incorporates a filtered seat, which not only adds a layer of protection against particulate contamination but also extends the service life of the regulator seat itself. The body, bonnet, and gauges are fully plated, providing superior protection against environmental corrosion and maintaining a clean, professional appearance suitable for lab settings. Furthermore, the regulator is designed to withstand vacuums generated during purging operations, ensuring that atmospheric contaminants can be effectively removed before gas flow begins.

Safety and Usability

Safety is integrated directly into the design with a built-in capturable preset safety relief valve, which protects downstream equipment and personnel from over-pressurization events. The large, 2-1/2 inch single scale gauges are designed for readability, allowing technicians to monitor cylinder and delivery pressure at a glance. With a delivery range of 0-60 PSIG and a CGA 350 inlet connection, this regulator is the definitive choice for professionals requiring exacting standards in specialty gas delivery.
