Mix Two Gases Directly from their Bottles

The BM-2M connects directly to a gas cylinder and mixes two gases in any ratio with inlet pressures up to 300 bar achieving a maximum outlet pressure of 8 bar. Integrated relief valves protect the downstream system from overpressure. The system is certified for use with Ar, He, CO₂ and N₂, with a mixing accuracy of 1%. The mixer weighs 3.5 kg and fits between the cylinder’s heads. — WITT-Gasetechnik GmbH & Co. KG, Witten, Germany
