Mini Five-Port Electrochemical Cell (10 mL) for Fundamental Electrochemistry Research, CFERM5PEC

A 5-port electrochemical cell is the standard configuration for professional laboratory research. The five ports allow for a "three-electrode" setup while providing two additional ports for environmental control (purging and venting) or auxiliary sensors. The mini volume of 10 mL electrochemical cell is suitable for only tiny amount of electrolyte involved in test. 

In a typical experiment, the ports are allocated as follows: (1) Port 1: Working Electrode (WE): The central port where your catalyst or material is placed. It is usually the largest port to accommodate various electrode diameters or rotating shafts. (2) Port 2: Reference Electrode (RE): Often placed in a Luggin Capillary to bring the reference point as close as possible to the working surface, minimizing IR drop. (3) Port 3: Counter Electrode (CE): Usually a Platinum or Graphite electrode. (4) Port 4: Gas Inlet (Purge): Used to bubble inert gas (Argon or Nitrogen) through the electrolyte to remove dissolved Oxygen, which can interfere with reductive measurements like CO2 reduction. (5) Port 5: Gas Outlet (Vent/Blanket): Allows the purge gas to escape. During the experiment, the inlet tube is lifted above the liquid to create an inert "blanket" that prevents Oxygen from re-entering.
