H Type Replaceable Membrane Electrochemical Cell for Three Electrode System Jacketed Single Layer Gas Purging

Product Overview

This H-type replaceable membrane electrochemical cell represents the pinnacle of modular laboratory reactor design, engineered to facilitate high-precision divided-cell electrolysis and multi-electrode analytical testing. Designed for researchers requiring strict isolation between anodic and cathodic half-reactions, this system maintains low ohmic resistance and prevents cross-contamination.

Commonly utilized in clean energy research and organic synthesis, this system is optimized for applications like carbon dioxide reduction, nitrogen fixation, and electro-catalyst evaluation. It serves research laboratories and industrial R&D centers focusing on battery technology, corrosion studies, and advanced electrolysis.

Manufactured to withstand demanding laboratory conditions, this unit utilizes high borosilicate glass and precision-machined fluoropolymer sealing components to ensure outstanding thermal stability and chemical resistance. This robust construction delivers consistent, repeatable results under continuous gas-purging conditions.

Key Features

• Modular Divided-Chamber Architecture: The dual-chamber configuration is split into distinct cathode (working electrode) and anode (counter electrode) compartments, separated by a user-provided ion-exchange membrane. A robust mechanical chain clamp provides consistent circumferential pressure across the interface, ensuring a leak-tight seal while allowing rapid membrane replacement without altering the cell's physical geometry.
• Optimized Low IR Drop Design: To minimize solution resistance (IR drop) and ensure highly accurate potential control, the reference electrode is positioned in the same chamber as the working electrode. This close physical proximity mitigates the ohmic resistance of the electrolyte path, ensuring precise potentiostatic and galvanostatic measurements during sensitive electrochemical trials.
• 360-Degree Rotatable PTFE Port Inserts: The glass entry ports are designed with external threads and host an inner core crafted from premium, CNC-machined polytetrafluoroethylene (PTFE) that rotates a full 360 degrees. This allows operators to achieve precise angular alignment of the elongated electrodes, keeping them perfectly parallel to the membrane surface for uniform current density.
• Advanced Gas Purge and Aeration Systems: The cell features integrated sub-surface gas delivery tubes tailored for specific gas-liquid reactions. Standard straight-tube purgers facilitate carbon dioxide reduction processes, while specialized L-shaped gas purge tubes are included for nitrogen reduction experiments, optimizing bubble distribution and mass transfer.
• Hermetic Compression Sealing System: Electrode integration is secured via heavy-duty PTFE plugs utilizing a specialized compression mechanism. By tightening the external POM caps against high-durability fluoropolymer O-rings, the system achieves a highly reliable, leak-free relative seal, protecting volatile electrolytes and sensitive reactions from atmospheric exposure.
• Overhead Dead-Volume Prevention: The single-layer glass vessel incorporates an innovative elevated base design. This smart structural geometry raises the active solution volume above potential dead zones, preventing fluid entrapment and ensuring homogeneous mixing and complete recovery of valuable target compounds.
• Jacketed Thermal Regulation Options: Available in both single-layer and double-layer configurations, the jacketed variant integrates an outer jacket for external water bath circulation. This allows researchers to continuously pump temperature-controlled fluid around the active volume, maintaining strict isothermal conditions for thermodynamic studies.
• Flexible, Scalable Chamber Volumes: Standard models range from 30 mL to 500 mL capacities to accommodate varying sample sizes, with specialized 10 mL versions utilizing a unique internal thread design. Additionally, the cell body can be customized to include auxiliary sampling ports, allowing real-time fluid withdrawal without disrupting the internal atmosphere.
