The Uniqsis Gas Addition Module II (GAM II) is a serpentine reactor that allows gases to be added “on demand” to reactions proceeding by diffusion through gas permeable membrane tubes under flow conditions.

With GAM II, your gas and liquid phases never touch directly. As the gas dissolved in the flowing liquid phase is consumed, more gas rapidly diffuses through the gas permeable membrane tube to replace it. For chemists looking to run efficient carbonylation or hydrogenation reactions, the new GAM II design ensures that the flowing liquid phase is free of undissolved gas bubbles, providing greater stability, constant flow rates, and reproducible residence times.
Available in 2 different versions – GAM II can be cooled or heated like a more traditional serpentine reactor. For the most efficient heat transfer, standard reactor external piping can be made from 316L stainless steel. Alternatively, a thick-walled PTFE version of the GAM II can be used, which provides improved chemical compatibility and the ability to view reaction mixtures through opaque walls. Based on the standard Uniqsis serpentine reactor mandrel, the GAM II serpentine reactor is fully compatible with the full range of high performance flow chemistry systems and other reactor modules.
