Small reference electrodes
Compatible with small analytical cells
Reference electrodes need to have an intrinsic redox potential that is stable. A large variety of small reference electrodes is available to cover all different electrolytes and applications.
In electrochemistry, the most basic equipment to be able to perform your experiment is a reference electrode. A reference electrode has a fixed electrochemical potential and is used to apply a potential difference to the electrode. Depending on your electrolyte and your system, you might want to prefer using chloride-based reference electrodes (Calomel, Ag/AgCl) or sulfate-based electrodes (Hg/HgSO4). Small reference electrodes are compatible with small analytical cells. Replacement kits are also available.
Aqueous media
Various electrodes are offered using either ceramics or porous glass as material for the junction.
