Straight Five Port Hermetic Electrochemical Cell with Internal Plug In Design and PTFE Lid

Product Overview

This innovative straight five-port hermetic electrochemical cell represents a significant advancement in absolute-sealed electrochemical analysis. Engineered for high-precision laboratory research, the system integrates a robust borosilicate glass body with a precision-machined polytetrafluoroethylene (PTFE) lid, establishing a contaminant-free environment for sensitive electrochemical measurements. The primary value proposition lies in its unique internal plug-in electrode port mechanism, which replaces traditional high-maintenance ground glass joints with an absolute hermetic seal that prevents gas leakage and external atmospheric contamination.

Designed primarily for rigorous three-electrode electrochemical testing, this system serves advanced research laboratories in electrocatalysis, battery development, corrosion science, and chemical synthesis. It is highly valued across both academic institutions and industrial research facilities where volatile solvents, air-sensitive compounds, or high-purity purge gases dictate absolute atmospheric isolation. The versatility of the platform accommodates sample sizes ranging from micro-analytical scales to process optimization volumes, ensuring high reproducibility and reliable data.

Engineered to withstand the demanding conditions of modern electrochemical research, the equipment delivers unwavering performance and reliability. Every component is selected and manufactured to guarantee long-term dimensional stability, exceptional thermal shock resistance, and broad chemical compatibility. Researchers can operate under vacuum or controlled pressure conditions with complete confidence, knowing the vessel maintains absolute integrity throughout prolonged testing cycles.

Key Features

• Hermetic Internal Plug-In Port Design: The electrode interfaces utilize an advanced internal jack-style insertion port engineered directly into the PTFE lid. This design eliminates the leakage risk associated with standard taper joints, ensuring an absolute hermetic seal that maintains a stable internal atmosphere during long-term experiments.
• High-Purity Borosilicate Glass Vessel: The cell body is constructed from premium high-borosilicate glass, offering superior optical clarity, low thermal expansion coefficients, and exceptional resistance to aggressive chemical solvents and acids. This allows researchers to visually monitor the electrode surfaces and reaction progress without risking structural degradation or chemical leaching.
• Precision CNC-Machined PTFE Lid: Each lid is custom-engineered using state-of-the-art CNC machining centers to ensure tight tolerances and perfect thread engagement. The virgin PTFE material provides universal chemical inertness, excellent sealing properties, and resistance to degradation across a wide range of operating temperatures.
• Single-Layer and Jacketed Double-Layer Configurations: The system is available in a standard single-layer configuration for room-temperature studies and an advanced jacketed double-layer version. The double-layer model features an integrated outer heating/cooling jacket for continuous circulation of water or thermal oil, enabling precise temperature control of the target solution.
• Integrated Gas Purging and Aeration Assembly: Equipped with specialized inlet valves and a matching aeration device, the cell supports efficient gas purging for deoxygenation or controlled gas-phase reactions. The inlet valve connects seamlessly to positive-pressure gas lines, facilitating uniform distribution of inert gases throughout the liquid phase.
• Vacuum and Safe Pressurization Performance: The absolute hermetic architecture allows the cell to be evacuated down to -100 kPa for air-sensitive chemistry. When configured with a round-bottom single-layer vessel, the system can safely support positive pressurization up to 0.6 MPa, opening new pathways for pressurized electrochemical synthesis.
• Optimized Five-Port Spatial Layout: The linear five-port configuration provides optimal spatial distribution for the working electrode, counter electrode, reference electrode, gas inlet, and gas outlet. This structured layout prevents spatial crowding and minimizes ohmic resistance, ensuring highly accurate and reproducible electrochemical data.
• Strict Electrode Compatibility Matching: Designed to work as a unified system, the internal insert ports are perfectly matched to compatible electrode shafts, removing the need for fragile glass frit salt bridges or complex Luggin capillaries. This optimized interface reduces assembly complexity and ensures a direct, low-resistance reference path utilizing silver/silver chloride electrodes.

Cell Configurations & Performance

Standard Volumes & Dimensional Matching

The standard capacities range from 10 ml to 500 ml. The threaded PTFE lid sizes are systematically matched to the volume of the cell body to maintain structural stability and seal integrity.

Why Choose This Product

• Unmatched Sealing Performance: The proprietary internal plug-in port design establishes an absolute hermetic seal without relying on messy joint grease or fragile ground glass connections. This ensures absolute protection for oxygen-sensitive or moisture-sensitive reactions and prevents toxic vapor leakage.
• Precision Custom CNC Machining: Backed by KINTEK's end-to-end PTFE machining capabilities, the cell lids are crafted from solid virgin PTFE blocks. This guarantees precise thread pitch, perfect port concentricity, and reliable dimensional stability that holds up over thousands of operational cycles.
• Versatile Temperature and Pressure Control: With both standard single-layer and jacketed double-layer options, our system fits seamlessly into any advanced thermodynamic study. Single-layer round-bottom configurations are engineered for pressure safety up to 0.6 MPa, allowing synthetic chemists to expand their experimental capabilities safely.
• Comprehensive Electrode Integration: By designing the cell and the electrode interfaces as a matched system, we eliminate the need for complicated salt bridge assemblies. The direct insertion path ensures robust electrical connectivity and optimized spatial geometry every time the cell is assembled.
