The Gas Addition Module from Uniqsis provides a safe and efficient means of performing gas-liquid reactions under continuous flow-through conditions. Its primary purpose is to provide a solvent feed stream pre-saturated with gas, but it can also be used as a reactor in its own right.
Fast, controllable gas saturation: Developed by scientists at Cambridge University in the UK1, the ingenious ‘tube-in-tube’ design promotes rapid diffusion of pressurised gas through gas-permeable tubing to quickly generate a continuous gas saturated solvent stream in typically less than 10 seconds (for H2). No undissolved gas bubbles to disrupt control of pressure and residence time!
Wide variety of applications at your fingertips: Compatible with a wide range of reactive gases (e.g. CO, CO2, H2, D2, ethene, ethyne, SO2) and organic solvents (e.g. THF, MeCN, MeOH, PrOH). Effortlessly perform heterogeneous and homogeneous gas-liquid reactions such as hydrogenation, ozonolysis, carbonylation, and direct synthesis of carboxylic acids.
Flexible: Connect in-line with any FlowSyn or other continuous flow reactor system.
Safe: Integral safety features (protective glass cover and gas pressure release valve) and the use of small gas volumes ensure safe operation in the lab. In addition, the convenient optional Portable Gas Reservoir (UQ1098) avoids the need to bring bulky pressurised gas cylinders into the lab.
