220-2002 - Miller Smith 220 Series Silverline High Purity Two-Stage CO2 Regulator, 0-15 PSI

Precision Gas Control for Analytical Laboratories

The Miller Smith 220-20-02 Silverline High Purity Analytical Two Stage Regulator is engineered to meet the exacting standards of modern laboratory environments. Designed specifically for high-purity, non-corrosive gas applications, this regulator excels in tasks requiring absolute consistency and cleanliness, such as gas chromatography. The unit features a CGA 320 inlet connection, making it suitable for Carbon Dioxide (CO2) service in analytical settings.

Advanced Two-Stage Design

One of the primary challenges in gas delivery is the "decay" effect, where delivery pressure fluctuates as the cylinder pressure drops. The 220-20-02 utilizes a robust two-stage design that effectively eliminates this issue. By stepping down the pressure in two intervals, the regulator provides a constant, unwavering delivery pressure from a full cylinder down to a nearly empty one. This feature is critical for thermal conductivity, flame ionization, and electron capture detectors where flow stability directly impacts data accuracy.

Superior Materials and Construction

To ensure the integrity of your gas stream, Miller Smith has equipped this regulator with a stainless steel diaphragm. Unlike rubber or neoprene diaphragms, stainless steel does not off-gas or absorb contaminants, ensuring that the purity of your carrier gases or calibration mixtures remains uncompromised. Additionally, the regulator body, bonnet, and gauges are fully plated, offering superior protection against corrosion and maintaining a clean, professional appearance suitable for lab environments.

Safety and Durability

Safety is paramount in high-pressure gas handling. This model includes a built-in capturable preset safety relief valve that protects downstream components from over-pressurization. The seat is filtered to trap particulates, extending the service life of the regulator and further enhancing gas purity. Furthermore, the design is robust enough to withstand vacuums generated during purging operations, adding versatility to its operational capabilities.
