223-2010 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 590

Precision Control for Analytical Applications

The Miller Smith 223-20-10 Silverline High Purity Analytical Two-Stage Regulator is engineered for environments where precision and purity are paramount. Designed specifically for high-purity, non-corrosive gas applications, this regulator is a staple in laboratories utilizing gas chromatography, thermal conductivity, flame ionization, and electron capture systems. The core of its performance lies in its two-stage design, which takes the high pressure from the cylinder and steps it down in two increments. This mechanical advantage ensures that the delivery pressure remains absolutely constant, even as the cylinder pressure drops from full to nearly empty, eliminating the need for constant manual adjustments during critical procedures.

Material integrity is critical in analytical settings, which is why the 223-20-10 features a stainless steel diaphragm. Unlike elastomeric diaphragms that can off-gas or absorb impurities, stainless steel ensures that the gas stream remains uncontaminated, preserving the integrity of your calibration mixtures and carrier gases. The regulator also includes a filtered seat, which not only adds another layer of gas stream purity but also protects the internal seating mechanism from particulate damage, significantly extending the service life of the unit.

Durability meets precision with the Silverline series. The body and bonnet are machined from rugged brass bar stock, providing a solid foundation that is then plated for superior protection against environmental corrosion and wear. The large 2-1/2 inch single-scale gauges are easy to read at a glance, allowing operators to monitor cylinder and delivery pressure with accuracy. Furthermore, the unit is designed to withstand vacuums generated during purging operations, making it highly versatile for complex gas management setups. With a delivery range of 0-200 PSIG and a CGA 590 connection, this regulator is the professional's choice for consistent, high-purity gas delivery.
