• Resumen

  • Reducing the volume of chemical waste is a fundamental principle of green chemistry. However, many experiments in the undergraduate analytical teaching laboratory ask for relatively large samples to achieve reasonable accuracy and precision. We developed a simple electrochemical cell that requires only 0.20 mL of sample to reliably produce ideally shaped cyclic voltammograms. The cell can be easily disassembled for cleaning and polishing of the working electrode.
