All PTFE Exchangeable Membrane Electrochemical Cell Dual Chamber Three Electrode Photoelectrochemical Cell for Laboratory Trace Analysis

Product Overview

This high-performance dual-chamber electrochemical cell is engineered for advanced laboratory research and rigorous industrial testing where chemical inertness is paramount. Constructed entirely from premium-grade polytetrafluoroethylene (PTFE), this cell features an innovative exchangeable membrane design that physically isolates the anode and cathode chambers. The system is designed to provide a completely stable, contamination-free environment for sensitive electrochemical processes, offering unparalleled chemical resistance and mechanical durability.

The system is highly versatile and serves as an ideal platform for a wide range of demanding applications, including electrocatalytic carbon dioxide reduction, nitrogen reduction reactions, photoelectrochemical water splitting, and through-plane ion conductivity measurements. By utilizing a robust PTFE cell body, this equipment handles highly aggressive media such as concentrated alkaline solutions (e.g., 2M KOH) at elevated temperatures without any structural degradation or chemical leaching. This makes it a preferred choice for research institutes, universities, and industrial R&D centers globally.

Designed with experimental accuracy and operational ease in mind, the unit incorporates features such as a 360-degree rotating inner core for perfect optical alignment and a dual-chamber sealing mechanism that simplifies membrane replacement. Researchers can operate with complete confidence in their data, knowing that the structural integrity of the cell prevents external contamination and minimizes potential measurement errors like IR drop. The cell stands as a reliable, highly adaptable solution for modern electrochemical and photoelectrochemical investigations.

Key Features

• Chemically Inert PTFE Construction: The entire cell body is precision-machined from high-purity polytetrafluoroethylene (PTFE), providing absolute chemical resistance against strong acids, concentrated bases, and aggressive organic solvents. It remains completely stable even in 2M KOH electrolytes at temperatures up to 80°C, ensuring zero contamination during long-duration experiments.
• Dual-Chamber Membrane Isolation: The cathode chamber (housing the working electrode) and the anode chamber (housing the counter electrode) are isolated by an exchangeable ion-permeable membrane. The two chambers are tightly clamped together using heavy-duty pass-through bolts, facilitating rapid membrane installation and replacement without compromising the airtight seal.
• Minimized IR Drop Configuration: To ensure highly accurate potential control and measurement, the reference electrode is positioned within the same chamber as the working electrode. This spatial arrangement shortens the electrical path through the electrolyte, drastically reducing IR drop during cyclic voltammetry and electrochemical impedance spectroscopy (EIS).
• 360-Degree Rotating Optical Alignment: Featuring an innovative external thread cap design and a 360-degree rotating inner PTFE core, this system allows operators to precisely align the electrodes with the built-in optical window. This ensures maximum light exposure and reproducible positioning for photoelectrochemical experiments.
• Quick-Exchange Quartz Window: The cell is equipped with a high-transmittance quartz plate optical window that can be quickly disassembled and replaced. This modular design simplifies cleaning, minimizes maintenance downtime, and allows for rapid swapping of optical elements.
• High-Integrity O-Ring Compression Sealing: The electrode entry ports are sealed using specialized PTFE plugs combined with compression O-rings and tightening screws. This design provides reliable gas tightness, preventing the escape of volatile gases or the intrusion of atmospheric air during controlled-atmosphere experiments.
• Versatile Sub-Surface Gas Purging: The cell includes a sub-surface gas aeration assembly to establish precise controlled atmospheres. Depending on the reaction type, users can select a straight-tube purging device (ideal for carbon dioxide reduction) or an L-shaped purging device (optimized for nitrogen reduction reactions).
• Extended Electrode Compatibility: Designed specifically to accommodate extended-length working, reference, and counter electrodes. This ensures deep immersion and stable electrical contact within the cell's active volume, optimizing current density distribution and data reliability.
