King size reference electrodes

Everyone needs a reference

In addition to small reference electrodes, larger and sturdier reference electrodes are also available. Various electrodes are available depending on the experiment conditions. Please also note a reference electrode dedicated to EIS measurements, where a capacitance in parallel is added to remove all the high frequencies artefacts of the reference electrodes.

More details on the electrodes are given in the specifications section. Please note that an adapter is recommended to connect these references to Bio-Logic instruments and that bridge tubes are also available to prevent the electrode from being contaminated by the electrolyte.
