These electrochemical cells, designed with a 30 mL volume capacity, incorporate a conical cell type featuring a gas-tight fitting and 4 necks (3 B10 and 1 B14 Joints) 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.
