Uncompromised EIS in the Micro-Ohm Region

Are you measuring true cell impedance, or just the inductance of your test cables?

Let's be real: performing high-frequency Electrochemical Impedance Spectroscopy (EIS) on high-capacity cells or short stacks is notoriously challenging. When impedances drop into the micro-ohm (µΩ) region, standard benchtop potentiostats lose their footing to cable inductance and signal distortion.

Kolibrik solved this at the hardware level. This uncompromised architecture powers both our Essential and Core potentiostat lines. Whether you need the Essential series for everyday reliable high-current testing, or the Core series to push the absolute physical limits of single-cell R&D, you get data you can trust.

Want proof? Look at the precision plot in the image—it was generated by our high-power Core model, the PTC-05100EW.

The data speaks for itself: a razor-sharp 1.0% precision at 10 µΩ even at 10 kHz, maintaining strict accuracy crossing the 1 mΩ threshold at 100 kHz. Thanks to our optimized design and high-speed acquisition (14-bit @ up to 20 Msps), we capture clean data exactly where others only see noise.

Stop compromising on your battery or electrolyzer modeling.
