221-4109 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580

Precision Control for Laboratory and Analytical Work

When your work demands absolute precision and gas purity, the Miller Smith 221-41-09 Silverline regulator is the professional's choice. Designed for the exacting standards of gas chromatography, flame ionization, and thermal conductivity applications, this regulator ensures that your carrier gases and calibration mixtures are delivered with unwavering stability. Unlike single-stage regulators that allow outlet pressure to rise as the tank empties, this two-stage model maintains your set pressure from a full cylinder down to the last few pounds, allowing you to focus on your results rather than adjusting your equipment.

The Silverline series is built to last and designed to perform. The exterior features a sleek, plated finish that resists corrosion and looks professional in any laboratory setting. Inside, a stainless steel diaphragm provides the delicate touch needed for fine pressure adjustments while ensuring that the regulator itself does not contaminate your high-purity gas stream. This makes it an excellent solution for labs using Argon, Nitrogen, or Helium where maintaining the chemical integrity of the gas is as important as controlling the flow.

Ease of use is a hallmark of the Miller Smith design. The large, easy-to-read 2-1/2 inch gauges let you monitor your gas supply at a glance, reducing eye strain and reading errors. The regulator is also equipped with a filtered seat, which acts as a first line of defense against debris that can cause leaks or creep, ensuring a long, trouble-free service life. Whether you are setting up a new chromatograph or upgrading your lab's gas delivery system, the 221-41-09 delivers the reliability and purity required for critical analytical tasks.
