252-8208 - Miller Smith 250 Silverline High Purity Oxygen Regulator, CGA 540, 0-100 PSI

Precision Control for High Purity Applications

The Miller Smith 252-82-08 Silverline High Purity Analytical Liquid Cylinder Regulator is a premium solution designed for the rigorous demands of laboratory and analytical environments. When dealing with high-purity gases, maintaining the integrity of the gas stream is paramount. This regulator addresses that need with a fully nickel-plated brass body, bonnet, and gauges. The nickel plating serves a dual purpose: it provides an aesthetically clean finish suitable for lab environments and, more importantly, offers superior corrosion resistance compared to standard brass, ensuring that the regulator itself does not introduce contaminants into your gas flow.

Engineered for Liquid Cylinders

Unlike standard industrial regulators, the 250 Silverline series is specifically engineered for use on liquid cylinders (dewars). It features a back-mount inlet connection, which positions the regulator correctly when attached to the liquid cylinder's gas use valve. This ergonomic design consideration simplifies installation and ensures the gauges are easy to read. Speaking of gauges, this model is equipped with large 2-1/2 inch single-scale gauges. These oversized dials make it incredibly easy for technicians to monitor cylinder volume and delivery pressure from a distance, enhancing safety and efficiency in busy laboratory settings.

Cryogenic Reliability

One of the critical challenges in regulating gas from liquid sources is the potential for cold temperatures to affect internal components. The Miller Smith 252-82-08 utilizes a large 1-7/8 inch stainless steel diaphragm. Stainless steel is the material of choice for cryogenic applications because it retains its flexibility and strength even when exposed to the lower temperatures often associated with high-withdrawal rates from liquid cylinders. This ensures precise pressure control and a long service life, preventing the drift and failure common in lesser regulators.

Exclusive Sure-Seat™ Technology

At the heart of this regulator is Smith’s exclusive Sure-Seat™ filtered seat technology. This innovative design incorporates a filter directly into the high-pressure seat assembly, preventing microscopic particles and contamination from entering the seating area. Debris is the number one cause of regulator failure and creep; by blocking it effectively, the Sure-Seat™ significantly reduces repair costs and downtime. With a delivery range of 0-100 PSIG and a CGA 540 connection for oxygen service, this regulator is the dependable choice for analytical work requiring stable, clean gas delivery.
