This electrochemical cell requires a user-supplied ion-exchange membrane and extended-length electrodes for operation. The semi-sealed design prohibits use in absolute sealing or vacuum applications.
- Membrane Compatibility Constraint: Verify membrane compatibility with the electrolyte before assembly to prevent chemical degradation or leakage.
- Seal Integrity Requirement: Inspect all O-rings and compression seals before each use to ensure proper containment of electrolyte and gases.
- Temperature Control Specification: The integrated water bath jacket enables precise thermal regulation for temperature-dependent electrochemical studies.
This procedure describes the assembly, membrane installation, and gas purging setup for the two-compartment electrolytic cell. Proper seal verification and electrode alignment are critical for accurate electrochemical measurements.
Required Equipment: User-supplied ion-exchange membrane, Extended-length working and reference electrodes, Sub-surface sparger (straight or L-type)
- Inspect seals and components
Inspect all O-rings, PTFE plugs, and glass surfaces for damage or debris before beginning assembly. - Install the ion-exchange membrane
Secure the user-supplied ion-exchange membrane between the cathode and anode chambers using the chain-sealed connections to ensure a leak-free seal. - Position the electrodes
Insert the working and reference electrodes into the same compartment and rotate the 360° PTFE inner core to achieve precise alignment. - Tighten the compression fittings
Tighten the POM outer cap to compress the O-rings around the PTFE plug, creating a gas-tight seal for each electrode port. - Connect the gas sparger
Attach the sub-surface sparger (straight for CO2 reduction or L-type for nitrogen reduction) to the gas inlet port for purging. - Fill and purge the cell
Fill each compartment with electrolyte and purge with the appropriate gas for at least 15 minutes to remove dissolved oxygen. - Connect the water bath jacket
Connect the double-layer jacket to a circulating water bath set to the desired experimental temperature before starting measurements.
How does the co-located working and reference electrode design in the ATOMFAIR double-layer electrolytic cell reduce uncompensated resistance (iR drop)?
The cell places the working and reference electrodes in the same compartment, minimizing the distance between them and thereby reducing uncompensated resistance (iR drop) for more accurate electrochemical measurements. This design is explicitly stated to effectively lower iR drop by the manufacturer.
What type of ion-exchange membrane is compatible with this replaceable-membrane electrolytic cell, and what precautions are needed?
The cell uses a user-supplied ion-exchange membrane; the chain-sealed connections enable quick replacement without compromising seal integrity. The manufacturer advises verifying membrane compatibility with the electrolyte before use and inspecting O-rings and seals prior to assembly.
What are the installation and operational requirements for the ATOMFAIR double-layer electrolytic cell regarding electrode length and sealing?
Extended-length electrodes must be used. The glass sealing uses an external threaded port with a 360° rotatable PTFE inner core for precise alignment, secured by a POM outer cap, and electrode seals are achieved via compression fittings with O-rings on the PTFE plug. The cell is not intended for absolute sealing or vacuum applications, and O-rings should be inspected before each use.
This ATOMFAIR® double-layer replaceable-membrane electrolytic cell offers a semi-sealed two-compartment design with co-located electrodes to reduce iR drop, an integrated water jacket for thermal control, and chain-sealed membrane connections for easy replacement, available in capacities from 30 mL to 250 mL.
Positive
- Co-located working and reference electrodes: Positions the working and reference electrodes in the same compartment to minimize uncompensated resistance (iR drop), improving measurement accuracy in three-electrode configurations.
- Integrated thermostatic water bath jacket: Double-layer glass construction includes a water jacket for precise temperature control, enabling temperature-dependent electrochemical studies such as reaction kinetics and thermal stability analysis.
Trade-offs
- Not suitable for absolute sealing or vacuum: The semi-sealed design is not intended for absolute sealing or vacuum applications; users must ensure proper sealing for their specific requirements and avoid high-vacuum conditions.
- Requires extended-length electrodes and user-supplied membrane: The cell design requires extended-length electrodes for proper insertion, and the ion-exchange membrane must be sourced separately, adding compatibility verification steps before use.
