254-2002 - Miller Smith Silverline 250 Series High Purity CO2 Liquid Cylinder Regulator 0-200 PSI

Precision Control for Analytical Applications

The Miller Smith 254-20-02 Silverline High Purity Analytical Liquid Cylinder Regulator is engineered to meet the rigorous demands of laboratory and analytical environments. Designed specifically for use with Carbon Dioxide (CGA 320), this regulator ensures that the purity of your gas stream is maintained from the cylinder to your instrument. The core of this performance lies in the large 1-7/8 inch stainless steel diaphragm. Unlike rubber or neoprene diaphragms that can off-gas or absorb impurities, stainless steel provides a non-contaminating surface that reacts precisely to pressure changes, ensuring stable delivery pressure even as the cylinder drains.

In analytical chromatography and high-purity gas handling, contamination is the enemy. Miller Smith addresses this with their exclusive Sure-Seat™ technology. This filtered seat design prevents microscopic particles and debris from entering the seating area, which is a common cause of regulator creep and failure. By protecting the seat, the regulator maintains a tight seal and consistent performance over a longer lifespan, reducing the risk of downtime in critical experiments or processes.

Optimized for Liquid Cylinders

Liquid cylinders present unique challenges for regulators, particularly regarding orientation and accessibility. The 254-20-02 features a rear entry (back mount) inlet connection, which allows the regulator to mount flush and securely to the liquid cylinder's gas use valve. This ergonomic design keeps the gauges facing forward and easy to read. The large 2-1/2 inch single scale gauges are designed for clarity, allowing technicians to monitor cylinder and delivery pressure from a distance. With a delivery range of 0-200 PSI, this unit is versatile enough for a wide variety of laboratory applications requiring medium pressure control.

Durability and Safety

Safety and longevity are paramount in the Silverline series. The body, bonnet, and gauge cases are nickel-plated, offering superior protection against corrosion and wear compared to standard brass regulators. This plating is especially beneficial in laboratory environments where chemical vapors may be present. Additionally, the regulator includes a built-in capturable preset safety relief valve, adding an extra layer of protection for both the equipment and the operator.
