Traditional Five-Port Electrolytic Cell 5-1000 mL ATOMFAIR®

This semi-sealed cell requires proper sealing of ground glass joints and O-ring compression fittings to prevent electrolyte leakage. Gas purging must be switched to overhead-only during measurements to avoid solution disturbance and electrode interference.

• Sealing Integrity: Inspect ground glass joints and O-rings before each use to ensure airtight sealing.
• Gas Purging Protocol: Use the F-type inlet for dual-mode purging, but maintain only overhead purging during electrochemical measurements.
• Electrode Compatibility: This cell requires extended-length electrodes for proper immersion; rotating disk electrodes are not compatible without increased overhead gas flow.
• Salt Bridge Positioning: The integrated salt bridge reduces uncompensated resistance by positioning the reference electrode close to the working electrode.
• Material Compatibility: The high-borosilicate glass and PTFE lid provide chemical resistance to common electrolytes but verify compatibility with aggressive solvents.

This procedure guides the safe assembly, gas purging, and operation of the semi-sealed electrochemical cell. Proper sealing and purging technique are critical to obtain accurate electrochemical measurements.

Required Equipment: Extended-length electrodes, Gas supply line

1. Inspect Seals
   Inspect all ground glass joints and O-rings for cracks, debris, or wear before assembly.
2. Assemble Electrodes
   Insert extended-length working, counter, and reference electrodes into the appropriate ports and tighten compression fittings to achieve a leak-free seal.
3. Purge the Cell
   Connect the gas supply to the F-type inlet and purge the electrolyte both below and above the surface.
4. Switch to Overhead Purging
   Adjust the gas flow to overhead-only before starting measurements to prevent solution disturbance and electrode interference.
5. Adjust for RDE Use
   Increase the overhead gas flow rate when using a rotating disk electrode to maintain an inert atmosphere above the electrolyte.

The ATOMFAIR Single-Layer Traditional Five-Port Electrolytic Cell features an integrated salt bridge that reduces uncompensated resistance and a dual-mode F-type gas inlet for purging above and below the liquid surface. However, it is incompatible with rotating disk electrodes and requires extended-length electrodes, which must be purchased separately.

Positive

• Integrated salt bridge reduces resistance: The salt bridge positions the reference electrode close to the working electrode, effectively lowering uncompensated solution resistance for improved measurement accuracy.
• Dual-mode gas purging capability: The F-type inlet tube allows gas purging both above and below the liquid surface, with the ability to switch to overhead-only during measurements to minimize solution disturbance.

Trade-offs

• Incompatible with rotating disk electrodes: The semi-sealed design does not support RDE use; for such applications, increased overhead gas flow is required to maintain atmosphere protection, which may compromise measurement conditions.
• Requires extended-length electrodes: Standard-length electrodes are not suitable due to the deeper cell geometry; extended-length electrodes must be ordered separately, adding to procurement complexity and cost.
