631-4110 - Miller Smith Silverline 630 Series Two-Stage Lecture Bottle Regulator CGA 590

Compact Reliability for Laboratory Environments

When your workspace is limited but your need for precision is high, the Miller Smith 631-41-10 Silverline Regulator is the professional's choice. This high-purity, two-stage regulator is specifically designed for use with lecture bottles, making it a staple in research laboratories, educational facilities, and testing centers. With the backing of Miller Smith's legacy in gas equipment, you can trust this device to deliver consistent performance in low-flow applications involving non-corrosive gases.

Stable Pressure Delivery

Fluctuating gas pressure can ruin experiments and damage sensitive equipment. The 631-41-10 solves this problem with its advanced two-stage architecture. By regulating the pressure in two steps, it eliminates the "decay" effect often seen in single-stage regulators attached to small tanks. Whether your lecture bottle is full at 3500 PSI or nearing empty, this regulator maintains a steady 0-15 PSI output, allowing you to focus on your work rather than constantly tweaking the dial.

Built to Last

Durability meets precision in the Silverline 630 Series. The regulator is constructed from solid brass bar stock, ensuring it can withstand the rigors of daily use. To enhance its longevity and appearance, the exterior components—including the body, bonnet, and gauges—are chrome-plated. This finish resists tarnishing and is easy to clean, a vital feature for clean-room or lab settings. The internal mechanism is equally robust, featuring a brass piston first stage and a high-grade 316 stainless steel diaphragm for the second stage, ensuring accurate response to pressure changes.

User-Friendly Features

The Miller Smith 631-41-10 is designed with the user in mind. It features a large, ergonomic adjusting knob that makes setting precise pressures effortless, even when wearing gloves. The dual 1-1/2 inch gauges are clear and legible, providing instant visual confirmation of your gas supply status. Additionally, the unit comes with a CGA 590 connection, ensuring compatibility with standard cylinders for sulfur hexafluoride, industrial air, and other compatible gases. For safety, a capturable relief valve is integrated into the design, providing peace of mind during operation.
