Over the years again and again we have constructed new intermediate vessels for various applications. Normally those intermediate vessels are assembled with a ceramics diaphragm on the top. The task of intermediate vessels is, to bring the reference electrode through a highly conductive electrolyte as close as possible to the sample, so that IR-waste is as small as possible. So we have intermediate vessels in curved form for rotating disk- and ring-disk electrodes, where the diaphragm faces up. We have some with a diaphragm mounted on the side, which are used for rotating cylinder electrodes. And we have some with a very thin top, for example to measure in batteries at positions, which are difficult to reach. The lower picture shows such an intermediate vessel. If you need an intermediate vessel, which you can't find on our website, just request. You can find several types on this page.
