These electrochemical cells, designed with a 100 mL volume capacity, incorporate a conical cell type featuring a gas-tight fitting and four necks (4 B14) crafted from robust borosilicate glass. The presence of electrode holes enhances adaptability to different experimental setups, providing increased versatility. The apparatus is characterized by easy handling, ensuring user-friendly operation. With applicability in a moderate temperature range from 0 to 100°C, it accommodates a diverse range of experimental conditions. Notably, it comes equipped with one B14 stopper for conducting experiments in inert conditions. The maximum temperature tolerance of 100°C further enhances its suitability for controlled environments and varied research requirements.
