256-0002 - Miller Smith 250 Series Silverline CO2 Liquid Cylinder Regulator 0-500 PSIG

High Purity Analytical Control for Liquid Cylinders

The Miller Smith 256-00-02 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered for precision and purity in laboratory and analytical environments. Designed specifically for use with liquid cylinders (dewars), this regulator features a back-mount inlet configuration that simplifies connection to the gas use port of cryogenic vessels. The unit is equipped with a CGA 320 inlet, making it the standard choice for Carbon Dioxide (CO2) applications requiring high-purity delivery.

At the core of this regulator is a large 1-7/8 inch stainless steel diaphragm. Unlike neoprene or rubber diaphragms, stainless steel prevents off-gassing and absorption, ensuring that the purity of the gas stream is maintained from the cylinder to your instrument. This material choice also provides extended service life in cryogenic applications where temperature fluctuations can degrade lesser materials. The regulator controls the delivery of gas phase product, not liquid, providing a stable delivery pressure range of 0-500 PSIG.

Durability meets precision with the Silverline series. The entire body, bonnet, and gauges are nickel-plated, offering exceptional resistance to corrosion and wear. This plating is particularly beneficial in laboratory settings where chemical resistance is paramount. Smith’s exclusive Sure-Seat™ filtered seat technology adds another layer of protection, preventing microscopic particles from entering the high-pressure seating area, thereby reducing maintenance costs and downtime.

Operators will appreciate the large 2-1/2 inch single-scale gauges, which allow for easy pressure monitoring from a distance. Whether used for bulk gas distribution, high-purity gas handling, or general laboratory use, the Miller Smith 256-00-02 delivers reliable performance backed by the quality of the Miller Smith brand.
