632-0007 - Miller Smith 630 Series Silverline Two-Stage Lecture Bottle Regulator CGA 510

Precision Control for Laboratory Applications

The Miller Smith 632-00-07 Silverline High Purity Two Stage Lecture Bottle Regulator is a specialized instrument designed to meet the rigorous demands of laboratory and analytical environments. Engineered as part of the renowned 630 Series, this regulator addresses the specific challenges associated with lecture bottles, where space is at a premium and precise pressure control is non-negotiable. The unit features a compact footprint without sacrificing the robust performance metrics expected from Miller Smith equipment.

At the core of its performance is the two-stage regulation mechanism. In lecture bottle applications, where cylinder volume is low, pressure decay can occur rapidly. A single-stage regulator would require constant adjustment to maintain the desired output. The 632-00-07 utilizes a brass piston first stage to step down the high inlet pressure (up to 3500 PSI), followed by a sensitive second stage that smooths out fluctuations. This ensures a stable delivery pressure of 0-50 PSI throughout the life of the cylinder, providing consistent flow for critical instrumentation and experiments.

Material integrity is paramount in high-purity applications. This model incorporates a 1-inch 316 stainless steel diaphragm in the second stage. Unlike elastomeric diaphragms that can off-gas or absorb contaminants, stainless steel ensures that the gas stream remains pure and unaffected by the regulator materials. The body, bonnet, and gauges are constructed from rugged brass bar stock and plated for superior protection against environmental corrosion. Sintered brass filters are integrated into the design to trap particulates, further extending the service life of the internal components.

Operational safety and ease of use are also key features. The regulator includes a built-in capturable preset safety relief valve, adding a layer of protection against over-pressurization. The large adjusting knob provides tactile feedback, allowing operators to dial in precise pressure settings with ease. With a CGA 510 inlet connection, this regulator is ready to interface with compatible specialty gas cylinders immediately.
