Alternative Divided Cell with a Filtered Glass Tube: A Cheap, Simple, and Easy Apparatus for Electro-organic Synthesis

H-type divided electrochemical cell is an important experimental apparatus for electro-organic synthesis by using reactive species, which is generated on the surface of the anode or the cathode. However, the preparation of H-type divided electrochemical cell at the laboratory level was expensive and not cheap. In this paper, we propose the insertion of cylinder tube equipped with the glass filter into sample tube, in order to enable anyone to easily and affordably achieve a divided electrochemical cell in organic synthesis.
