Electrochemical cell for simultaneous measurements of optical properties

The main part of the cell is formed by a hollow Teflon cylinder, which also restricts its volume. As a bottom face, a glass working electrode covered with a conducting material is used; top face is formed by a glass coverslip. The system is leakproof owing to EPDM rubber rings and via pressing the whole inner part together between two plastic plates. Openings in the Teflon cylinder allow circulation of analytes and insertion of electrodes.
