Conventional Five Port Electrochemical Cell Borosilicate Glass Jacketed Three Electrode System

Product Overview

This premium electrochemical cell is engineered to provide a highly controlled and chemically inert testing environment for quantitative electrochemistry. Constructed from high-purity borosilicate glass combined with a precision-machined polytetrafluoroethylene (PTFE) lid, the vessel offers outstanding resistance to aggressive chemical agents and thermal stress. The standard five-port configuration provides researchers with the necessary ports to comfortably arrange a complete three-electrode system alongside essential gas handling and salt bridge accessories, making it an indispensable tool for high-precision analytical research.

Designed primarily for academic and industrial research laboratories, this system excels in diverse applications including electrocatalysis, corrosion evaluation, battery material testing, and electrochemical sensor development. The cell accommodates standard analytical configurations while maintaining structural integrity over repeated sterilization and cleaning cycles. Whether performing cyclic voltammetry, electrochemical impedance spectroscopy (EIS), or Tafel polarizations, this unit provides the stable, leak-free, and clean baseline environment necessary for capturing highly reproducible data.

Operating under demanding laboratory conditions requires equipment that eliminates the risk of sample contamination and gas leakage. The meticulously engineered sealing interfaces on this system prevent ambient atmosphere ingress, ensuring the integrity of oxygen-sensitive experiments. Backed by extensive engineering expertise, this electrochemical vessel delivers the robust mechanical design, chemical compatibility, and precise component alignment needed to support critical research breakthroughs in chemistry, metallurgy, and material science.

Key Features

• Premium Borosilicate Glass Construction: Manufactured using high-grade borosilicate glass, the cell body provides exceptional optical clarity for real-time visual observation of electrode surfaces and gas evolution, alongside outstanding resistance to thermal shock and strong acids.
• Conical PTFE Ground Joint Lid: The specialized inverted cone PTFE lid matches seamlessly with the finely ground glass neck of the cell body. This design creates a highly reliable gas-tight seal without the need for vacuum grease, eliminating a major source of chemical contamination in the electrolyte.
• Optimized F-Type Dual-Phase Gas Purging: The included F-type gas inlet tube facilitates dual-phase gas management. It allows users to bubbled gas below the liquid level to rapidly deoxygenate the electrolyte before a test, and then smoothly redirect the flow to the headspace as a blanket layer to prevent oxygen re-entry without causing convective noise during active measurements.
• Integrated Salt Bridge for Low Resistance: Equipped with an adjustable glass salt bridge, the system positions the reference electrode tip in close proximity to the working electrode. This effectively minimizes the solution resistance (IR drop) between the two electrodes, ensuring highly accurate potential control and measurement.
• Elastomeric Compression O-Ring Seals: The electrode ports on the PTFE stoppers utilize a secure compression sealing mechanism. By tightening the threaded plastic collars, internal O-rings compress against the elongated electrode shafts, establishing an adjustable, reliable gas-tight seal that accommodates varying electrode insertion depths.
• Variable Volume Configurations & Conical Base: Available in a wide capacity range from 5 mL to 500 mL to suit different sample constraints. The lower-volume models (5 mL to 20 mL) feature a pointed-bottom (V-shaped) design to maximize liquid depth, ensuring that even micro-volume samples can fully submerge the active electrode elements.
• Advanced Jacketed Thermal Control Option: The system is available in a double-wall jacketed configuration, enabling constant-temperature fluid circulation from external baths. This allows researchers to study the precise temperature dependence of electrochemical kinetics and thermodynamic properties.
• Customizable Multi-Port Architecture: For demanding setups requiring real-time physical monitoring, the standard five-port architecture can be customized with additional ports (e.g., six-port configuration) to integrate digital thermometers, temperature sensors, or auxiliary dosing tubes.
