Small-Volume Conical Three-Electrode Electrochemical Cell

Overview

The Small-Volume Conical Three-Electrode Electrochemical Cell is a precision glass cell designed for high-sensitivity electrochemical measurements in limited sample volumes (typically 5 – 20 mL). Its conical geometry ensures efficient mixing, enhanced mass transport, and minimal solution resistance, making it ideal for research laboratories that require accurate and repeatable electrochemical data using only a small quantity of electrolyte.

Design & Working Principle

The cell follows the classical three-electrode configuration, comprising a working, counter, and reference electrode, each positioned symmetrically within a conical chamber to ensure uniform current distribution. The conical base reduces stagnant zones and facilitates efficient bubble release during gas-evolving reactions. Gas inlet and outlet ports allow continuous purging with inert gas (N₂ / Ar) and integration with gas traps or bubblers for oxygen-free operation.

Key Features

• Sample capacity: 5 – 20 mL, optimised for limited electrolyte studies.
• Material: High-purity borosilicate glass with PTFE fittings for chemical resistance.
• Configuration: 5-port design (working, counter, reference, gas inlet/outlet, gas bubblers).
• Compatibility: Supports standard 6 mm OD electrodes, Ag/AgCl or Hg/HgO references, and Pt/Au/GC working electrodes.
• Sealing: Ground-glass joints with chemical-resistant O-rings ensure leak-tight operation.
• Applications: Electrocatalysis, corrosion testing, battery half-cell studies, redox reaction kinetics, and gas-diffusion electrode characterisation.
