610-00020000 - Miller Smith 610 Series High Purity CO2 Regulator, 0-25 PSI, CGA 320

Precision Control for High Purity Applications

The Miller Smith 610 Series Silverline High Purity Brass Single Stage Regulator is engineered specifically for analytical and laboratory environments where gas purity is paramount. Designed to manage non-corrosive gases such as Carbon Dioxide (CO2), this regulator features a CGA 320 inlet connection and delivers a precise pressure range up to 25 PSI. The core of its performance lies in the specially designed stainless steel diaphragm, which offers superior sensitivity and accuracy compared to standard elastomeric diaphragms. This construction eliminates the risk of off-gassing and absorption associated with rubber components, ensuring that the gas stream remains uncontaminated from the cylinder to your instrument.

To further safeguard system integrity, the 610 Series utilizes a metal-to-metal seal between the body and the diaphragm. This design choice creates a leak-tight barrier that maintains the high purity standards required for gas chromatography, mass spectrometry, and other sensitive analytical techniques. A 316 stainless steel filter is integrated into the inlet to trap any particulate matter, protecting the regulator seat and downstream equipment from debris. The filtered seat design adds another layer of reliability, extending the service life of the regulator even in demanding duty cycles.

Safety and versatility are also key components of the 610-00-02-00-00 model. The bonnet is threaded for panel mounting and includes a capturable vent (1/16" FNPT), allowing for the safe piping of vented gases away from the work area in the unlikely event of a diaphragm failure. The body is machined from brass nickel-plated bar stock, providing a robust and corrosion-resistant housing that stands up to the rigors of daily use. With a delivery range that accommodates vacuum applications (up to 30" HG) and positive pressure up to 25 PSI, this regulator offers the flexibility needed for complex gas delivery systems.
