632-4200 - Miller Smith Silverline 630 Series Two-Stage Lecture Bottle Regulator, 0-50 PSI

Precision Control for Laboratory Applications

The Miller Smith 632-42-00 Silverline High Purity Two-Stage Regulator is engineered to meet the exacting demands of laboratory environments. Designed specifically for lecture bottles and low-flow applications, this regulator combines a compact footprint with the robust performance expected from Miller Smith's Silverline series. The unit features a two-stage reduction system, which is critical for maintaining a steady delivery pressure as the gas supply in the cylinder decreases. This stability is paramount in analytical and research settings where pressure fluctuations can compromise data integrity.

High Purity Construction

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated to provide superior protection and a clean aesthetic suitable for lab use. The heart of the regulator features a 1-inch 316 stainless steel diaphragm in the second stage. This stainless steel interface ensures that the gas path remains uncontaminated by elastomeric outgassing, preserving the purity of non-corrosive specialty gases. The first stage utilizes a brass piston design, renowned for its durability and ability to handle high inlet pressures up to 3500 PSI.

User-Friendly Design

Space is often at a premium in laboratory fume hoods and benches. The 630 Series Silverline regulators boast a slim design that fits easily into tight quarters without sacrificing accessibility. The large adjusting knob allows for smooth, precise control of the delivery pressure within the 0-50 PSI range. Additionally, the unit comes equipped with a stainless steel needle valve on the outlet (1/8" tube connection), providing operators with fine-tune control over the flow rate directly at the source. Safety is also integrated into the design with a built-in capturable preset safety relief valve.

Reliable Performance

For professionals managing specialty gases, the 632-42-00 offers a reliable solution for non-corrosive gas delivery. The inclusion of sintered brass filters adds a layer of protection for internal components, preventing debris from causing premature wear or failure. Whether used for chromatography, calibration gases, or general research, this Miller Smith regulator delivers the consistency and purity required for high-stakes industrial and scientific work.
