SVC-3C Oxygen-free Voltammetry cell - for application at low temperature

By using SVC-3C oxygen-free Voltametry cell, researchers can get rid of influence of oxygen in the cell by bubbling nitrogen gas, and also run the experiments at low temperatures.

SVC-3 Voltammetry cell

Features

For low temperature measurement, three special attention need:
1. Fluctuation of temperature-dependent reference electrode potential.
2. Increase of the solution resistance due to a decrease of supporting electrolyte salt solubility.
3. Incorporation of condensation of water vapor.

Using SVC-3C Voltammetry Cell:
1. Reference electrode is setting away, using sample holder.
2. Micro electrode is used to allow for a measurement in high resistivity solution.
3. This cell is closing.
