H Type Replaceable Membrane Electrochemical Cell with Sampling Port for Gas Liquid Phase Reactions

Product Overview

This high-performance electrochemical cell is engineered specifically for sophisticated electrocatalytic and electrosynthetic investigations where absolute chamber separation and precise product analysis are paramount. Featuring a dual-chamber H-type architecture, the system is designed to isolate the working electrode (cathode) and counter electrode (anode) reactions using an ion-exchange membrane. The integrated sampling port enables direct, real-time extraction of liquid-phase products without exposing the inner reaction environment to ambient air, preserving volatile compounds and ensuring the integrity of kinetic studies. By facilitating seamless gas-liquid mass transfer and eliminating solution dead zones, this system provides researchers with highly reproducible electrochemical data.

Optimized for cutting-edge energy research, this equipment is the standard configuration for carbon dioxide reduction reactions (CO2RR), nitrogen reduction reactions (NRR), hydrogen evolution reactions (HER), and oxygen evolution reactions (OER). The dual-chamber design prevents the re-oxidation or reduction of generated products at the opposing electrode, which is critical for accurate Faradaic efficiency calculations. Designed to house standard three-electrode configurations, the cell ensures that the reference electrode is located within the same chamber as the working electrode. This spatial arrangement dramatically reduces uncompensated solution resistance, enabling highly accurate potential control under diverse electrolyte conditions across academic, industrial, and green-technology research laboratories.

Constructed from high-purity borosilicate glass and premium fluoropolymers, this unit represents the pinnacle of laboratory engineering and reliability. The cell body resists thermal shock and chemical attack from aggressive acid or alkaline electrolytes, ensuring a long operational lifespan. The precise sealing mechanism, utilizing custom-machined components, guarantees zero gas leakage during long-duration experiments. Researchers can operate with complete confidence, knowing that the structural integrity of the cell maintains a stable gas-liquid-solid interface, yielding highly consistent voltammetric, chronopotentiometric, and impedance spectroscopy measurements.

Key Features

• Dual-Chamber Membrane Isolation: The cathode and anode chambers are completely isolated via a user-selected ion-exchange membrane, held securely in place by an ergonomic, quick-release chain clamp. This setup allows for rapid membrane replacement and cleaning while ensuring an airtight, leak-free seal between the two chambers.
• Integrated High-Integrity Sampling Ports: Specialized sampling ports are built directly into the borosilicate glass chambers, enabling syringe-based liquid extraction at regular intervals. This design prevents atmospheric contamination, making it ideal for tracking intermediate products in real-time.
• Ohmic Drop (R-Drop) Optimization: The chamber geometry is meticulously calculated to place the reference electrode in close proximity to the working electrode within the same half-cell. This arrangement minimizes uncompensated resistance, producing cleaner cyclic voltammetry and chronopotentiometry curves.
• Suspended Chamber Floor Design: Single-layer cell bodies are engineered with an elevated/suspended inner bottom. This advanced structural design eliminates solution dead zones where reactants or products could settle, ensuring homogeneous concentrations throughout the electrolyte volume.
• 360-Degree Rotating PTFE Inserts: The cell lid features a fully rotatable fluoropolymer insert that allows the working electrode to be aligned parallel to the membrane interface. This ensures a uniform electric field distribution across the electrode surface, eliminating local current density variations.
• Threaded Compression Caps: Secure sealing of the cell lid is achieved using external glass threads and high-durability POM compression caps. These caps compress the internal PTFE plugs against the glass rim, preventing gas escape even during high-flow purging operations.
• Specialized Gas Purging Interfaces: Each chamber is equipped with dedicated gas inlet and outlet ports. Users can choose between a straight-tube purger optimized for carbon dioxide reduction (CO2RR) or an L-shaped purger designed to maximize gas-liquid interaction in nitrogen reduction (NRR) setups.
• Jacketed Temperature Control Option: Available in both single-layer and double-layer jacketed configurations. The jacketed model allows continuous circulation of heat-transfer fluids, ensuring precise isothermal control for temperature-dependent thermodynamic studies.
