World-Class Power, Globally Trusted. Precision to the decimal is our baseline. That’s why the global electrochemical leader, Gamry Instruments, partners with us to offer Kolibrik Potentiostats. This synergy of robust high-current hardware and world-class expertise delivers a dependable, high-ROI investment for gigafactories and research labs worldwide.
Kolibrik Potentiostat/Galvanostat is an invaluable tool for electrochemical research and development, quality control, fuel cell and battery testing, corrosion research, etc. This multipurpose device offers various electrochemical measurement techniques like cyclic voltammetry/amperometry, linear sweep voltammetry/amperometry, chronoÂamperometry, EIS, charge/discharge cycling, and other specialized battery testing protocols, including method sequencing and scripting. It enables deep and precise insight into the electrochemical processes of your desire.
The electrochemical impedance spectroscopy (EIS) analysis is the ultimate technique to unlock the secrets of your electrochemical system during its standard operating conditions. The EIS method measures the impedance of a system over a wide range of frequencies. It provides valuable information about the system's response at different timescales, which is of particular interest in studying the reaction kinetics at the electrode surfaces, the diffusion of reactants and products, the ohmic resistance of the electrolyte, etc.
Kolibrik Potentiostat/Galvanostat provides wide measurement range up to ±10 V and ±100 A with high accuracy and precision in both potentiostatic and galvanostatic measurement mode. With its capability to measure high-current densities our potentiostat/galvanostat is best suited for analysis of electrolyzers, fuel-cells and stacks, and batteries.
Kolibrik Potentiostats deliver exceptional accuracy, maintaining tight error margins even at such low impedance values and frequencies, as demonstrated by the wide 0.5% accuracy contour.
The wide 0.1% precision contour highlights the instrument's capability to resolve extremely small impedance variations, ensuring reliable data for highly sensitive electrochemical measurements.
Uncompromised Data. Designed to fit your budget.
A more accessible price tag usually means stripped-down features. Not with Kolibrik. Potentiostat Essential was designed with a single goal: to deliver uncompromised electrochemical performance while maximizing your research budget.
It is perfectly suited for testing individual hydrogen fuel cells, solid-oxide cells, and standard lithium batteries. Additionally, its high-precision EIS makes it an ideal tool for fundamental applied research and routine quality control where extreme currents are not required.
Key parameters
High-Current Architecture. Stable Data at Scale.
High-current testing often introduces system noise and signal degradation. The Core Line is engineered to overcome this. It delivers kilowatt-level power for your scale-up applications while maintaining high-resolution EIS and uncompromising data integrity.
Designed for demanding environments, typical applications include high-power water electrolyzers, redox-flow batteries, and lithium battery packs with high-current requirements. It provides critical diagnostics for advanced R&D and manufacturing testing.

MegaEIS for Batteries
MegaEIS for Fuel Cells and Electrolyzers
Whether you need to analyse electrolysers, fuel cells, batteries we have the right solution for you.
Electrolyzers use electricity to split water into hydrogen and oxygen, which can be used as clean and renewable fuels. For detailed EIS characterization, you can use our potentiostats for single cell research or for short stack evaluation. Our EIS source models can be used for characterization of full electrolyzer stacks.
Fuel cells and fuel cell stacks convert hydrogen and oxygen into electricity and water, providing clean and efficient energy for various applications. We provide potentiostats for single cell research, zero-voltage loads for high-power fuel cell EIS characterization under high current conditions over 1000 Amperes, or EIS analysis solution for powerful stacks with multichannel EIS acquisition capability.
Lithium batteries, redox-flow batteries, etc. are essential for storing and delivering energy from renewable sources. They offer advantages such as long lifetime, good scalability, and seamless integration in the electrical grid. For batteries, you can use our high-current potentiostats or high-power EIS analyzers combining load and source modes in one device.
Didn't choose from our standard models? You need a higher current, more channels, a different configuration?
We will customize your testing setup according to your needs and preferences.
