Medenus RS251 Gas Pressure Regulator & Shut Off Valve

The CONCOA 315 Series is a chrome-plated brass, dual-stage cylinder regulator designed for inert and non-corrosive gases in medical laboratory applications. Its two-stage design ensures stable outlet pressure or flow by compensating for gradual cylinder pressure drops. The regulator provides point-of-use control across five pressure ranges, from 0–15 PSIG (0–2 BAR) to 0–200 PSIG (0–14 BAR). It comes with a standard 2–15 lpm flowgauge calibrated for CO₂ (for lasers and cell growth chambers) or a custom thermal mass flowmeter-calibrated gauge for specific gases. While suitable for medical lab use, it is not intended for therapeutic use in humans.
