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.

 

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.




 

 

Example of the SVC-3C Voltammetry Cell application at low temperature

SVC-3C Oxygen-free Voltammetry Cell was tested at -40°C, by Department of Chemistry, Graduate School of Science, Osaka University.
