Frosted Joint Sealing
Supports compatible electrodes and sealing components while helping reduce evaporation and contamination.
SEALED DUAL-CHAMBER ELECTROCHEMICAL CELL
H-type Sealed Electrolytic Cell (Two Electrodes)
Designed for electrochemical experiments in which the anolyte and catholyte must remain separated. The frosted-joint dual-chamber structure supports a two-electrode configuration, while the central connection accepts a compatible membrane, such as Nafion, to reduce direct mixing and cross-interference.
PRODUCT OVERVIEW
Product Overview
Designed for controlled solution separation, ion transport
and compartmentalized electrode reactions.
The cell consists of two independent electrolyte chambers connected through a central membrane interface. A compatible ion-exchange membrane or separator can be installed between the chambers to maintain ionic conduction while limiting convective mixing. Frosted ports accommodate the working and counter electrodes used in common two-electrode experiments. Electrode placement can be adjusted to suit the experimental design.
Before ordering:
Select the capacity according to the required volume per
chamber and confirm the electrode diameter, port arrangement,
membrane type, sealing requirements and chemical compatibility.
Ion-exchange membranes and electrodes are sold separately.
DESIGN FEATURES
Product Features
A compact dual-chamber platform for separated electrolytes
and two-electrode testing.
Dual-chamber Separation
Keeps the anolyte and catholyte separate when reactants, products or electrolytes should not mix directly.
Two-electrode Support
Accommodates working and counter electrodes positioned in separate chambers for routine electrochemical tests.
Replaceable Membrane
The central interface accepts compatible separators, including selected Nafion membranes.

HOW TO USE
Operating Procedure
Clean, prepare and leak-test the cell using a method
compatible with the intended electrolyte.
Confirm the Setup
Check capacity, electrode dimensions, ports, membrane
and both electrolytes.
Prepare the Membrane
Cut, soak or activate the membrane according to the
supplier's instructions.
Install and Leak-test
Mount the membrane flat, tighten evenly and perform a
low-risk leak test.
Add Electrolytes
Fill both chambers slowly and leave sufficient free
space for the electrodes.
Install Two Electrodes
Insert the working and counter electrodes into their
respective chambers and confirm immersion positions.
Remove Bubbles
Check the membrane and electrode surfaces and reposition
them if required.
Start the Test
Verify wiring, liquid levels and sealing before starting
the electrochemical program.
Drain and Clean
Remove the solutions promptly, clean appropriately and
dry all parts completely.
CARE & PRECAUTIONS
Care and Precautions
Avoid incompatible cleaners, mechanical impact, thermal
shock and forced assembly.
Before the Experiment
- Verify chemical compatibility among the electrolyte, cell body, seals, membrane and electrodes.
- Inspect all frosted joints, the membrane interface and sealing surfaces.
- Keep the membrane flat and free from folds, particles and misalignment.
- Confirm the diameter and insertion depth of both electrodes before installation.
After the Experiment
- Drain both chambers promptly to prevent deposits or crystallization.
- Use a compatible solvent selected for the remaining chemicals.
- Avoid abrasive tools, sudden temperature changes and mechanical impact.
- Dry all parts completely and store them clean and protected from dust.
FAQ
Frequently Asked Questions
All answers are expanded for quick specification and
operating checks.
Are the membrane and electrodes included?
No. The membrane, working electrode and counter electrode must be selected and purchased separately.
How should I select the capacity?
Consider the required volume per chamber, electrode immersion depth, reaction duration and available sample volume while allowing sufficient free space.
Can a Nafion membrane be used?
Yes, provided its dimensions and chemical compatibility match the experiment. Prepare it according to the membrane supplier's instructions.
Why should the liquid levels be similar?
A large level difference can create pressure across the membrane and cause permeation, deformation or uneven sealing stress.
What should I check if leakage occurs?
Stop the experiment and inspect membrane alignment, surface contamination, connection uniformity and the condition of the sealing components.
Can the electrode ports be customized?
If the standard arrangement is unsuitable, provide the electrode diameters, insertion depths, port quantities and positions before ordering.
