Replaceable Membrane H Type Electrochemical Cell for Three Electrode Gas Aeration Experiments

Product Overview

This advanced replaceable membrane electrochemical cell represents a significant evolution in H-type cell design, specifically engineered to meet the stringent demands of modern electrochemical research. By dividing the system into distinct working and counter electrode compartments separated by an easily replaceable membrane, this system minimizes cross-contamination and allows for precise control of half-cell reactions. The integration of a built-in Luggin capillary directly at the junction of the reference and working electrode chambers solves a major pain point in traditional designs by significantly reducing solution resistance and ohmic drop during testing.

Ideal for a wide range of applications, this equipment is the preferred choice for researchers in electrocatalysis, lithium-ion battery development, hydrogen evolution reactions, and carbon dioxide reduction. Its dual-chamber design makes it uniquely suited for systems requiring absolute separation of anodic and cathodic products, such as photoelectrochemical water splitting and redox flow battery membrane crossover studies. Industrial procurement teams and academic research labs alike rely on this unit to deliver highly reproducible cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance spectroscopy data.

Built with absolute confidence in long-term reliability, the cell body is fabricated from premium high borosilicate glass, known for its exceptional chemical inertness and resistance to thermal shock. Paired with our precision-machined polytetrafluoroethylene (PTFE) sealing components, this cell guarantees leak-free operation and maintains structural integrity even under highly acidic, basic, or volatile organic solvent environments. Every unit undergoes rigorous quality control to ensure that your lab receives an instrument capable of executing highly sensitive, trace-level electrochemical analyses without background interference.

Key Features

• Precision-Engineered Luggin Capillary: An integrated Luggin capillary is strategically positioned at the junction between the reference and working electrode chambers. This unique geometry allows the reference electrode probe to be placed in extremely close proximity to the working electrode surface, drastically reducing the internal resistance (IR) drop to ensure that the measured potential reflects the true interfacial potential at the working electrode.
• User-Friendly Replaceable Membrane Interface: The dual-chamber structure uses a specialized chain clamp configuration to secure the junction between the cathode and anode compartments. This design allows researchers to easily insert, align, and replace user-supplied ion-exchange membranes within seconds. The reliable mechanical pressure applied by the chain clamp ensures a uniform, leak-proof seal across the membrane surface, preventing electrolyte bypassing.
• Suspended Single-Layer Cell Architecture: The cell body features a high-clearance, elevated single-layer structure. Unlike conventional glass cells with flat bottoms that can trap droplets or accumulate trace residues in hard-to-clean crevices, this suspended design eliminates hidden solution zones, facilitating complete draining and thorough cleaning between trials.
• Dual Sealing Adaptability: To accommodate diverse experimental requirements, this system is offered in both relative and absolute sealing configurations. The relative sealing system is ideal for standard reactions where mild atmosphere isolation is sufficient, while the absolute sealing configuration is engineered for air-sensitive, oxygen-free, or highly volatile reactions, offering a totally closed environment.
• Threaded PTFE Compression Seals: The interface between the glass ports and the electrode components features high-precision internal threads. By tightening the robust, CNC-machined PTFE caps, the system applies controlled vertical force to squeeze high-performance elastomer sealing rings, providing a highly reliable gas-tight and liquid-tight seal without applying excessive stress to the glass.
• Advanced Electrode Integration and Sealing Options: Depending on the sealing configuration chosen, the electrode entry points are engineered for absolute integrity. For relative sealing, the system utilizes high-performance PTFE plugs with compression screws to deform the O-rings around the elongated electrodes. For absolute sealing, the cell features an innovative PTFE cover with integrated internal headphone-jack style sockets, allowing the electrodes to plug directly inside the cell structure for an impenetrable seal.
• Sub-Surface Gas Purging and Aeration Assembly: The system includes a dedicated gas inlet tube that extends below the liquid level, allowing for direct bubbling of inert or reactive gases into the electrolyte. This allows for rapid deaeration or the precise establishment of a gas-saturated environment, which is critical for gas-involving reactions like electrochemical carbon dioxide reduction.
• Scalable Customization and Sampling Port Integration: For laboratories requiring intermediate product analysis, the glass body can be customized with an additional sampling port. This port allows for the extraction of liquid samples at specified intervals during long-term electrolysis runs without disrupting the internal pressure or atmospheric composition.
