To establish electro-synthetic methods in academic research as well as in the chemical industry commercial availability of suitable standardized electrochemical cells is crucial. To tackle this point, C. Gütz and S. R. Waldvogel developed a highly modular flow cell for the continuous electrosynthesis of fine chemicals and pharmaceutical active intermediates and agents. The setup allows identification of important process parameters for later up-scaling on a technical scale. This flow system can be purchased as ElectraSyn Flow to provide the electro-synthetic community with an adequate electrochemical equipment. (ElectraSyn flow).
