ZP is the world leader in electrochemical assay, sensor, and biosensor development, including binding assays. On this page, we highlight the hardware required for developing an impedance spectroscopy assay. This page primarily focuses on Electrochemical Impedance Spectroscopy (EIS), although we also provide links to some of ZP’s screen-printed electrodes and biosensors.
On this page, you will find buttons for the following:
- AnaPot EIS: This instrument is used in our labs. You don’t need to worry about the specifications. If you are developing electrochemical sensors and assays, this instrument is recommended.
- The cable: We provide a link to a cable that terminates in 2 mm banana plugs and also comes with crocodile clips. However, we recommend using the connectors linked on this page, as crocodile/alligator clips can lead to high impedance connections and potentially confuse your results.
- The connector: ZP’s recommended screen-printed electrodes and biosensors have a 7 mm width. When clicking the button, choose the 7 mm option. Additionally, the potentiostat cable from ZP has 2 mm banana plugs, so select that option. However, on this page, we have simplified the process by directly linking to the correct products.

As a secondary consideration, we have provided links to our screen-printed electrodes and biosensors below. We have intentionally limited the links to our recommended carbon and gold electrodes since EIS assays are typically constructed using carbon or gold. If you are in the development phase, we highly recommend carbon over gold. This recommendation is based on the high global demand for gold and its relative scarcity, making carbon a more cost-effective platform for both research and manufacturing phases
