Here, we report the design and application of an electrochemical flow cell that provides excellent mixing and enables high current densities on research-relevant scales (<= 1 g, up to 10 g scale). The cell design, embedding a turbulence promoter and cooling layers, as well as pressure stability, allows the use of high current densities and provides a tool for efficient high-throughput synthesis applications. The cell performance was demonstrated for reaction conditions screening and material production (436 mmol scale) with a current density of 1000 mA/cm(2) in the oxidative bis-methoxylation of furan as a reaction model.
