Chrome-Plated Brass Barstock, Single Stage Cylinder Regulator for Inert Medical Laboratory Gas Applications

The CONCOA 305 Series regulator is designed for medical laboratory use. It provides point-of-use pressure control for gases in cylinders with pressures below 500 PSIG (35 BAR), or primary pressure control for inert gas applications that can tolerate minor outlet pressure fluctuations due to cylinder depletion. Like most CONCOA regulators, the 305 Series is rated for maximum inlet pressures of 3000 PSIG (210 BAR) or higher, depending on configuration.

The regulator can include a standard 2–15 LPM flow gauge calibrated for carbon dioxide, or a custom 2–15 LPM calibration for any non-corrosive gas or gas mixture. CONCOA uses a thermal mass flowmeter to size the outlet orifice according to the specific gas and desired flow. While the 305 Series features medical-standard inlet and outlet connections, it is not intended for therapeutic use in humans. For applications requiring constant outlet pressure or flow, CONCOA recommends the 315 Series two-stage regulator.
