Replaceable Membrane H Type Electrochemical Cell for Three Electrode Experiments with High Borosilicate Glass and PTFE Sealing Components

Product Overview

This high-precision electrochemical cell system is specifically engineered to meet the demanding requirements of academic research and industrial laboratory investigations. Designed as a classic dual-chamber H-type configuration, this apparatus allows for the complete isolation of the cathodic and anodic chambers, preventing the crossover of reaction products while facilitating unimpeded ionic transport. The system features a modular membrane mounting assembly, which is ideal for evaluating ion-exchange membranes or conducting sensitive electrochemical reactions where product segregation is paramount.

The cell body is constructed from high-grade borosilicate glass, offering superior thermal shock resistance and optical clarity, which allows for visual monitoring of electrocatalytic processes or gas evolution. The chamber architecture includes a specialized hollow-layer profile that eliminates solution dead zones and blind spots, ensuring uniform solute concentrations and consistent kinetic conditions. With a standardized volume capacity of 10ml, this system is optimized for high-value catalysts, limited-volume liquid electrolytes, and precise analytical trials.

Built to support rigorous experimental designs, the system provides two distinct sealing options to cater to varying levels of air sensitivity: relative sealing for routine liquid-state analysis and absolute sealing for highly sensitive anaerobic electrochemistry. By co-locating the reference electrode and the working electrode within the same chamber, this equipment minimizes uncompensated solution resistance (IR drop), resulting in highly reproducible cyclic voltammetry and impedance data. This system stands as a testament to precision engineering, ensuring high performance under complex testing conditions.

Key Features

• Dual-Chamber Membrane Interface: The system splits the reaction environment into distinct working and counter electrode compartments separated by an ion-exchange membrane. A heavy-duty chain clamp locks the chambers securely, enabling rapid membrane replacement while maintaining a hermetic, leak-proof barrier.
• Optimized IR Drop Mitigation: The spatial layout of the glass chambers ensures that the reference electrode resides in the immediate vicinity of the working electrode. This reduces the uncompensated electrolyte resistance path, delivering superior potential control and highly accurate voltammetric sweeps.
• High-Grade Borosilicate Glass Construction: Crafted from premium chemical-resistant borosilicate glass, the single-layer cell body incorporates a unique hollow geometry. This specialized structural design actively prevents solution entrapment and dead spaces, ensuring uniform electrochemical diffusion throughout the 10ml volume.
• Precision-Engineered Internal Thread Glass Joints: The connection ports on the glass body utilize an internal thread design that interfaces seamlessly with high-purity fluoropolymer components. Tightening the threaded fittings compresses the O-ring seals, forming a highly secure joint without requiring vacuum grease.
• Modular Sealing Options: Users can configure the cell for relative sealing using a compression screw mechanism on a solid polytetrafluoroethylene plug, or absolute hermetic sealing via a proprietary capped design with integrated inner-jack connectors.
• Sub-Surface Gas Purging Array: Equipped with an integrated gas aeration tube that extends below the liquid level, the system permits efficient purging and saturation of the electrolyte. This design enables precise control over the atmospheric headspace and dissolved gas concentrations.
• Customizable Extraction Ports: The glass cell body can be customized to include auxiliary sampling ports, allowing researchers to withdraw aliquots or introduce reagents mid-run. This functionality preserves the cell's internal environment while facilitating real-time kinetic analysis.
• Chemically Inert Fluoropolymer Fittings: All seals, caps, and plugs are machined from high-performance fluoropolymers, ensuring absolute resistance to aggressive acids, strong bases, and organic solvents. This material choice prevents contamination and guarantees structural integrity over years of continuous laboratory use.
