SP Wilmad-LabGlass Suprasil Electrolytic Assembly, Varian, Radiopan

Flat Electrolytic Cells have two 10/30 outer joints, one for the Gas Bubbler and one Platinum Electrode at the top and a single 5/20 outer joint at the bottom for the other Platinum Electrode. The flat section is either CFQ or Suprasil®. The remainder of the Flat Cell is CFQ. You need a minimum of 15 mL of sample solution to make contact with the electrodes and gas bubbler. The cell width for JEOL® spectrometers is 10mm outside; product number WG-810-J-A (-Q). For all other spectrometers, the cell width is 10.5 mm outside, product number WG-810-A (-Q).

The Gas Bubbler Assembly is a three-piece Pyrex® chamber which holds part of your sample. It has three 10/30 outer joints at the top for the Gas Bubbler and two Calomel Electrodes. The lower 10/30 inner joint fits into the top of the Flat Electrolytic Cell. Nitrogen should be bubbled through the solution before and during your experiment to remove paramagnetic oxygen and mix the sample during electrolysis; product numbers WG-810-B-1, WG-810-B-2, WG-810-G.

Platinum Electrodes are prepared using 0.016 in. (0.4 mm) diameter wire. The upper electrode, WG-810-C, uses 8 in. (203 mm) of platinum and acts as the working electrode in oxidation reactions. The lower electrode, WG-810-D, has only 2 in. (50 mm) of platinum and acts as the auxiliary electrode in oxidation reactions. If you add a few drops of mercury to the cell, the lower electrode can be used as the working cathode in reduction reactions. Each Platinum Electrode incorporates a Pt-to-W weld. The tungsten (W) external wire lets you quickly clip your potentiostat leads to the electrode.
