The Unsealed H-Type Membrane Cell provides a versatile, open-access design for electrochemical research requiring rapid sample manipulation and ease of electrode handling. Constructed from durable borosilicate glass, each chamber (20 mL to 250 mL) is separated by a replaceable ion-exchange membrane, enabling effective ionic conduction while keeping anodic and cathodic environments distinct. Without gas-tight sealing, this configuration allows immediate intervention during experiments, making it ideal for method development, quick parameter adjustments, and educational demonstrations. The cell supports standard three-electrode arrangements and can be adapted for various research needs. Its simplicity and flexibility make it a cost-effective choice for laboratories focusing on exploratory electrochemical work or short-duration testing.
