Product News: Compact performance: Screen-printed and interdigitated electrodes

Discover how you can boost your research with screen-printed and interdigitated electrodes

15 Jun 2020

Fast, inexpensive, reliable, and versatile – this is what Metrohm’s screen-printed and interdigitated electrodes promise. Screen-printed electrodes allow you to perform a large number of experiments with low volumes of sample, and without electrode pretreatment or maintenance. Interdigitated electrodes can be used for impedance or conductivity measurements and for (bio)sensor development, notably for rapid point-of-care identification of viruses of various kinds. Metrohm offers a large variety of materials and configurations, so that you can find the best electrodes for your research requirements.

Key features of screen-printed and interdigitated electrodes from Metrohm: 

  • Inexpensive, single-use sensors eliminate electrode maintenance
  • High reproducibility between electrodes
  • Easy to use, small, and robust solution for in situ experiments
  • Versatile and customizable: Many configurations, sizes, and materials available
  • Interdigitated electrodes for impedance or conductivity measurements
  • ISO 13485 certification

Faster results, lower costs, less maintenance: Screen-printed electrodes 

Simplify your research with screen-printed electrodes. With these small, inexpensive sensors, you can perform in situ, decentralized experiments with low amounts of sample. As these electrodes are designed for single use, you don’t need to worry about pretreatment or maintenance procedures. Metrohm offers screen-printed sensors in a variety of working-electrode materials, including carbon, gold, platinum, and other metals. Thanks to the high reproducibility between electrodes, these sensors are suitable for a wide range of applications, such as DNA, enzyme, or immunobased (bio)sensors and in the development of sensing platforms in clinical, environmental, food, or other industry analysis.

Impedance and conductivity measurements made easy: Interdigitated electrodes 

If you want to perform impedance or conductivity measurements or if you are developing (bio)sensors, then interdigitated electrodes from Metrohm could be the right choice for you. These electrodes consist of two opposing metal-digit electrodes with a width and separation between 5 and 200 µm. Metrohm supplies these sensors in a variety of substrate materials and electrode materials, giving you full flexibility in designing your experiments.

Your research, your electrodes: Customization options

Get exactly the electrodes you need for your research. Metrohm can adjust the design, configuration, materials, and dimensions of the electrodes to your requirements. On request, Metrohm will also test new materials and work with new geometries – the possibilities are endless.

Screen-printing and photolithography 

Screen-printing and photolithography technologies enable a vast range of combination options in terms of inks used and electrode materials. The manufacturing process involves the successive deposition of layers of inks on solid materials. Metrohm is therefore able to produce the exact electrode you need, with the specific materials, geometries, and dimensions for your research. 

ISO 13485 certification

With a high production capability and global distribution network, combined with a valid ISO 13485 certification «Manufacturing of sensors for medical devices», this means testing procedures developed on Metrohm electrodes can be reliably scaled up for larger operations, with easier approval by regulatory agencies.

Lab kits: Complete training courses

For use in education and training, Metrohm offers dedicated lab kits. These kits contain the analyte (sample), the screen-printed electrodes required for a practical analysis session, and two manuals: the Professor’s manual offering a theoretical and practical framework for structuring the session and the Student’s manual outlining the steps to follow for the development of analytical methods.

With the help of these kits, students can learn the basics of various electrochemical techniques, such as cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, and flow-injection amperometry.
