This pressurized electrochemical cell is designed for controlled laboratory experiments under elevated pressure conditions. With a total internal volume of 50 mL and a maximum operating pressure of 10 bar, it provides a robust and versatile platform for electrochemical studies.

The cell features a chemically resistant PEEK chamber and lid, sealed with an O-ring and secured with two metal clamps, ensuring reliable, leak-tight operation. It is equipped with inlet and outlet ports for fluid or gas handling, as well as a dedicated port for a temperature probe. When a probe is not used, the port can be securely sealed with a plug.

The cell supports both 2-electrode and 3-electrode configurations, offering flexibility for a wide range of electrochemical measurements. While the example configuration shown in pictures accommodates a plate-type working electrode using a sample holder, the design is also compatible with disk electrodes.

All connections are based on Swagelok PFA fittings, some of which are modified with precision-drilled through-holes to allow for the integration of electrodes and a temperature probe. Please note electrodes are not included and must be selected separately (see compatible options below). This cell is not intended for hydrothermal reactions. Pressure should be supplied externally using a compressed gas system. Customization options, including alternative materials and design modifications, are available upon request.

Application note

This pressurized electrochemical cell is designed for a wide range of laboratory-scale experiments where controlled pressure conditions are required. Typical applications include:
