The Screen-Printed Electrode (SPE) Holder is a versatile tool designed to facilitate characterization of thin/thick film planar electrodes and electrochemical (bio)sensors. It enables experiments with nearly all available on the market screen-printed electrodes (please see compatibility table below). The main function of that tool is the secure and leakproof mounting of the SPE and adapting it to a wide range of cell attachments i.e. static Batch-Cell (included in Screen-Printed Electrode Holder), dynamic Flow-Cell, in situ Raman Cell, UV-Vis spectroscopy cell, and many more coming soon. Other possibilities are available on request through customization service. The holder accommodates SPEs with dimensions ranging from 7 mm to 10.2 mm wide, 0.05 mm to 0.7 mm thick and longer than 20 mm (SPEs are not included in this product). The holder allows quick exchange of the SPE/sensor with easy-to-handle closing system. The SPE/sensor can be easily slipped into the holder where it is securely held in place with spring loaded jig. The Cell Attachment slides in the guide rails, which then is being locked with the connection plate. Additionally, the guide rails with cell attachment can also be secured with thumb screw. The connection plate has two threaded holes (M3, 20 mm spacing) which allow more permanent fixing of cables, batch connection board and other interfacing devices. This connection plate can be customized on request. The default Batch-Cell Attachment has 25 mm2 opening and allows measurements with sample volume up to 450 µL. The O-ring between the cell and the SPE top surface ensures good seal and can be selected from the set included in the holder to level the difference in SPEs thickness. The holder elements are constructed with materials that are chemically resistive to a wide range of electrolytes (Stainless Steel and PEEK). The connection plate is made of anodize Aluminum. The Cell Attachments are made of PEEK as standard, other materials are available on request. It well fits aqueous (EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements.

Application note SPEs are typically based on a classical three-electrodes approach with one centrally positioned working electrode, a small reference electrode and an auxiliary electrode around. It is a low-cost solution suitable for electroanalysis (mainly environmental pollutants, food quality), flow systems (monitoring of industrial processes), nanotechnology or as an electrochemical transducer in biosensor development (clinical analysis). SPEs can be used for a single use applications, or used for continuous monitoring, depending on their type and structure.
