222-0102 - Miller Smith Silverline 220 Series Two-Stage High Purity CO2 Regulator, 0-100 PSI

Precision Analytical Control for High Purity Applications

The Miller Smith 222-01-02 Silverline High Purity Analytical Two-Stage Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for Carbon Dioxide (CO2) applications utilizing a CGA 320 connection, this regulator ensures the integrity of your gas stream is maintained from the cylinder to the instrument. The core of its performance lies in the stainless steel diaphragm, which provides precise pressure control while eliminating the risk of elastomeric off-gassing that can contaminate sensitive samples.

Stability is paramount in analytical work, and the two-stage design of the 220 Series excels by delivering a constant outlet pressure regardless of fluctuations in the supply cylinder. As the cylinder pressure drops, single-stage regulators often experience a rise in delivery pressure; the 222-01-02 eliminates this variable, allowing for reliable, unattended operation. This makes it an ideal choice for gas chromatography applications, including thermal conductivity, flame ionization, flame photometry, and electron capture detectors where carrier gas stability is critical.

Durability meets precision with a rugged brass bar stock body that is fully plated, along with the bonnet and gauges, offering superior protection against corrosion and maintaining a clean, professional appearance in the lab. The unit features a filtered seat to trap particulates, extending the service life of the regulator and further protecting downstream equipment. With a delivery range of 0-100 PSI and large, easy-to-read 2-1/2 inch gauges, monitoring and adjusting parameters is straightforward and accurate.

Safety and versatility are built-in, featuring a capturable preset safety relief valve to protect against over-pressurization. Additionally, the regulator is designed to withstand vacuums generated during purging operations, ensuring it integrates seamlessly into complex gas delivery manifolds and systems.
