Using a GAM II, gas and liquid phases do not come into direct contact with each other at any point

The Gas Addition Module II (GAM II) from Uniqsis is a coil reactor that permits gas to be introduced to reactions performed under flow-through conditions by diffusion through gas-permeable membrane tubing.

Using a GAM II, gas and liquid phases do not come into direct contact with each other at any point. As the gas dissolved in the flowing liquid phase is consumed, more gas rapidly diffuses though the gas-permeable membrane tubing to replace it. For chemists looking to perform efficient carbonylation or hydrogenation reactions - the design of the GAM II ensures the flowing liquid phase does not contain any undissolved gas bubbles, thereby delivering greater stability, consistent flow rates and reproducible residence times.

Available in two versions, the GAM II can be cooled or heated just as with more conventional coil reactors. To ensure efficient heat transfer, the standard outer reactor tubing can be manufactured from 316L stainless steel. Alternatively, a thick-walled PTFE version of the GAM II is available to offer improved chemical compatibility and visualisation of the reaction mixture through the opaque tubing walls.

Based on a standard Uniqsis coil reactor mandrel, the GAM II is compatible with the company’s range of high-performance flow chemistry systems and other reactor modules.
