Asynt – Uniqsis gas management module

The Gas Addition Module 1 (GAM 1) provides a safe and efficient means of performing gas-liquid reactions under continuous flow-through conditions.

Based on an ingenious ‘tube-in-tube’ design developed by scientists at Cambridge University in the UK1, it promotes rapid diffusion of pressurised gas through gas-permeable tubing to quickly create a gas saturated solvent stream in typically less than 10 seconds.

Liquid (usually in the form of an organic solvent) is passed through a gas-permeable inner tube which is nested inside a closed, thick-walled outer tube filled under pressure with a reactive gas. The gas is able to diffuse across the membrane into the liquid phase, but the liquid cannot move in the opposite direction.

  • Add to an existing FlowSyn or other flow reactor system
  • Rapidly generate a continuous gas-saturated solvent stream
  • Effortlessly perform gas-liquid reactions in flow
  • Optional Portable Gas Reservoir
  • Built-in features for safe gas management


The Gas Addition Module is 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) and is designed to be connected in-line with any FlowSyn continuous flow reactor. Its primary purpose is to provide a solvent feed stream pre-saturated with gas, but it can also be used at ambient temperature as a reactor in its own right.

An alternative gas-liquid reactor (GAM II) that is able to supply gas on demand to a flowing reaction is also available.
