Product Description
Product Overview
The FrankLab Non-Sealed Double-Layer Water Bath Electrochemical Cell is a temperature-controlled electrochemical reaction vessel designed for experiments that require precise thermal regulation, easy electrode access, and non-pressurized operation.
Featuring a double-jacket glass structure, this cell allows external circulation of thermostatic fluid (water or oil), ensuring uniform temperature distribution throughout the electrolyte during electrochemical measurements.
This design is widely adopted for electrocatalysis screening, electrodeposition, corrosion testing, battery research, and long-duration electrochemical experiments.
Product Versions
1. Single-Layer Version
•Single glass chamber
•Open / non-sealed operation
•PTFE screw lid with electrode ports
