221-0007 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 510

Uncompromised Control for Specialty Gases

When your work depends on the absolute consistency of your gas supply, the Miller Smith 221-00-07 Silverline Regulator delivers the performance you need. Designed for professionals working with specialty gases and high-precision instruments, this two-stage regulator eliminates the "decay" often seen in single-stage regulators. As your cylinder empties, typical regulators allow the outlet pressure to rise, requiring constant manual adjustment. The 221-00-07 maintains your set pressure from a full cylinder down to nearly empty, allowing you to focus on your process rather than monitoring your gauges.

Ideal for Sensitive Instrumentation

This regulator is the perfect companion for sensitive equipment like gas chromatographs, thermal conductivity detectors, and flame ionization units. The high-purity construction features a stainless steel diaphragm, which is crucial for preventing contamination in your gas line. Standard rubber diaphragms can release trace chemicals or absorb the gas passing through them, altering the composition of your calibration mixtures. By using stainless steel, Miller Smith ensures that the gas entering your instrument is exactly the same as the gas leaving the cylinder. The plated finish on the body and gauges not only looks professional but also resists tarnishing and corrosion, keeping your setup clean and functional for years.

Built for the Long Haul

Durability meets precision in the Silverline series. The regulator includes a filtered seat that acts as a barrier against microscopic debris, a common cause of regulator failure and creep. This attention to detail extends the life of the regulator and reduces maintenance downtime. The large 2-1/2 inch gauges are designed for clarity, allowing for quick checks of your gas status at a glance. Whether you are managing carrier gases in a lab or controlling specialty mixtures in a manufacturing environment, the Miller Smith 221-00-07 provides the reliability, safety, and precision required for high-stakes applications.
