Suitable for standard H-type cells and compatible electrochemical accessories.
AmazonProduct Overview
The H-type replaceable membrane electrochemical cell consists of two independent chambers separated by an ion-exchange membrane. The cathode chamber is used for the working electrode, while the anode chamber is used for the counter or auxiliary electrode. Users can install a suitable membrane according to the experiment.
The two chambers are secured with stainless-steel clips for easy disassembly and membrane replacement. The reference electrode can be placed on the same side as the working electrode to shorten the measurement distance and reduce the influence of solution resistance.
Both sealed and open configurations are available. The sealed version supports nitrogen purging, gas introduction, evacuation, and gas collection. The open version is intended for routine electrochemical testing.
Structural Features
- Vessel material: high-borosilicate glass.
- Lid material: polytetrafluoroethylene (PTFE).
- Good resistance to acids, bases, and a wide range of electrolytes.
- Two-chamber structure with a replaceable ion-exchange membrane.
- Separated chambers reduce the influence of anode-side products on the cathode chamber.
- Stainless-steel clip fixation allows convenient disassembly.
- Capacities include 10, 20, 30, 50, 100, 150, 200, 250, 300, and 500 mL.
Differences Between Sealed and Open Versions
| Item | Sealed Version | Open Version |
|---|---|---|
| Suitable Experiments | Sealing, gas introduction, evacuation, nitrogen purging, and gas collection | Routine electrochemical testing |
| Vessel and Lid | Threaded opening with a large sealing ring | Flat opening without threads |
| Electrode Ports | Threaded ports with sealing components | Through-holes without sealing bolts |
| Gas Ports | Four standard Φ3.2 mm gas ports | No gas ports by default; ports can be customized |
| Membrane Maintenance | Clip-fixed and easy to replace | Clip-fixed and easy to replace |
Default Port Layout
Sealed Version
Left cathode chamber: two Φ6.2 mm electrode ports and two Φ3.2 mm gas ports. Right anode chamber: one Φ6.2 mm electrode port and two Φ3.2 mm gas ports. All electrode and gas ports are threaded and supplied with sealing components.
Open Version
Left cathode chamber: two Φ6.2 mm electrode through-holes. Right anode chamber: one Φ6.2 mm electrode through-hole. Gas ports and other port positions can be customized.
Standard Φ6.2 mm ports are suitable for electrodes approximately 6 mm in diameter. Confirm the port diameter or request customization before using electrodes of other diameters.
Applications
- Two-chamber electrolysis and ion-exchange membrane experiments.
- Battery materials and electrolyte research.
- Fuel-cell and redox-system testing.
- Separate cathode and anode reaction studies.
- Nitrogen purging, deoxygenation, and gas collection.
- Electrocatalysis, corrosion, and water-treatment research.
- Experiments requiring reduced influence of anode products on the cathode chamber.
Use
- Select the sealed or open configuration according to the experiment.
- Install the ion-exchange membrane between the two chambers and secure it with the stainless-steel clips.
- Install the working, auxiliary, and reference electrodes according to the function of each chamber.
- For the sealed version, check that the vessel, lid, large sealing ring, and electrode sealing rings are correctly installed.
- Close unused threaded ports with solid sealing screws.
- Connect gas tubing to the Φ3.2 mm gas ports when gas handling is required.
- After adding electrolyte, check for leaks and air bubbles.
- Use at normal temperature and pressure, preferably at 20–40°C.
- Clean the vessel, lid, and membrane-contact areas promptly after the experiment.
Frequently Asked Questions
How should I choose between the sealed and open versions?
Choose the sealed version for gas purging, evacuation, gas collection, or deoxygenation. Choose the open version for routine three-electrode testing.
Are the ion-exchange membrane and electrodes included?
No. The membrane and electrodes must be selected separately according to the experiment.
What electrode diameter fits the Φ6.2 mm ports?
The standard ports are mainly suitable for electrodes approximately 6 mm in diameter. Confirm the port diameter in advance for other electrode diameters.
Can different electrolytes be used in the two chambers?
Yes. The ion-exchange membrane separates the two chambers, allowing different electrolytes to be used according to the experimental design.
Can the center membrane be replaced?
Yes. Release the clips and replace the user-supplied ion-exchange membrane.
Must every port on the sealed version be used?
No. Unused ports should be closed with the supplied solid sealing screws to maintain the seal.
