252-0002 - Miller Smith 250 Series Silverline High Purity CO2 Regulator 0-100 PSI

High Purity Precision for Liquid Cylinders

The Miller Smith 252-00-02 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered for critical applications requiring precise gas control and minimal contamination. Part of the renowned 250 Silverline Series, this single-stage regulator is specifically designed for use with liquid cylinders (dewars), featuring a rear-entry back mount configuration that simplifies connection and reduces strain on piping systems. It is an essential component for laboratories, bulk gas distribution systems, and high-purity gas handling setups.

Constructed from rugged brass bar stock and finished with electroless nickel plating, the body and bonnet offer superior corrosion resistance and durability. The core of its high-purity performance lies in the large 1-7/8 inch stainless steel diaphragm. Unlike elastomeric diaphragms, stainless steel prevents off-gassing and maintains the integrity of the gas stream, ensuring that high-purity gases remain pure from the cylinder to the application. This makes it particularly effective for analytical applications where trace contamination cannot be tolerated.

This model is equipped with a CGA 320 inlet connection, standard for Carbon Dioxide (CO2), and delivers a pressure range of 0-100 PSIG. It incorporates Smith's exclusive Sure-Seat™ filtered seat technology, which protects the seating area from debris and contamination, significantly extending the service life of the regulator and reducing maintenance downtime. Large 2-1/2 inch single-scale gauges provide clear, easy-to-read pressure monitoring from a distance, ensuring operators can verify system status at a glance.
