Rotating cylinder and glass cell

Rotating cylinder test cells can be used to accelerate the erosion corrosion effects of carbon dioxide (CO2). The diagram below shows the main features of such equipment:

1. Reference electrode
2. Gas inlet
3. Gas outlet
4. Luggin capillary
5. Platinum counter electrode
6. Rotating cylinder
8. Temperature probe
9. Water in from loop
10. pH-electrode
11. Working electrode
