Five-necked Electrochemical Cell Set up

Captions

---

1. Five-neck cells are available as a specialised design, with or without a water jacket
2. The cell features five ground-glass taper ports: one central port and four side ports
3. an F-shaped dual port
4. Top port: Bubbling port used to introduce gas into the electrolyte via a submerged tube.
5. Blanket port: Directs gas into the headspace above the electrolyte to maintain a positive inert gas atmosphere
6. The dual-port design is particularly useful for corrosion studies and when using RDE/RRDE electrodes, where achieving a physical seal can be challenging.
7. Water seal: Once filled, it acts as a one-way valve, regulating internal pressure and isolating the system from the external environment
8. Use PTFE taper ports to achieve a secure seal around electrodes
9. A Luggin capillary is provided for the reference electrode port
10. Next, we’ll demonstrate electrode installation. (Electrodes are not included.)
11. Let’s begin with the working electrode
12. The port is large enough to accommodate RDE and RRDE electrodes
13. Use the blanket port to maintain positive gas pressure where a physical seal is difficult to achieve
14. A user-selected working electrode holder or disk electrode can be used with the cell
15. The port provides a secure seal for bespoke electrodes up to 20 mm wide when mounted with a compatible electrode holder
16. Follow these steps to achieve a secure seal
17. Select an appropriate reference electrode for your system
18. The Luggin capillary allows placement of the reference electrode closer to the working electrode
19. Note: Fill the salt bridge and allow equilibrium to establish before assembly
20. Use the supplied PTFE thread seal to secure the Luggin capillary if required
21. Make sure the Luggin Capillary is directed towards the Working Electrode
22. Let’s now install the counter (auxiliary) electrode
23. A platinum wire can be used  
24. Alternatively, a coil, plate, mesh, or graphite rod may be used. Here, a reinforced 10 mm × 10 mm platinum mesh is shown
25. A range of spare parts is included to support your research are PTFE Tape, Glass Port Covers, Additional FKM fluoroelastomer O-ring, Extra POM electrode securing screws and O-rings, PTFE Electrode Stoppers, Glass Stoppers
26. Please refer to the manual for additional information
