Squidstat Venta High-Current Potentiostat/Galvanostat (±20 A) with 2 MHz EIS

High-current electrochemistry with integrated EIS The Squidstat Venta is a single-channel potentiostat/galvanostat engineered for experiments where high current control and impedance insight are both essential. In potentiostatic operation, the instrument drives a defined electrode potential and measures the resulting current response; in galvanostatic mode, it enforces current and measures the corresponding potential. Integrated electrochemical impedance spectroscopy (EIS) applies a small AC perturbation to resolve kinetic, charge-transfer, and transport processes across frequency—supporting mechanistic interpretation beyond DC-only testing. Key specifications and capabilities Voltage scan range: ±6 V Maximum current: ±20 A (high-power control for demanding cells) EIS frequency range: 10 µHz to 2 MHz High impedance input suited to low-leakage measurements and stable reference sensing Switchable grounding (floating or earth-referenced) to match experimental setups Onboard data backup memory (16 GB) for failsafe experiment recovery Fast waveform support for advanced pulse/step methods and rapid voltammetry regimes Software workflow and integration The Squidstat User Interface software includes prebuilt methods plus a drag-and-drop experiment builder , with key setpoints and sampling parameters adjustable during runs. Multiple Squidstat units can be connected to a single computer to scale into a multi-channel workstation—useful for parallel materials screening or repeated-cell studies. Typical applications Battery formation and high-rate cycling support experiments (with complementary battery cyclers where appropriate) Electrolysers and fuel cells: catalyst and MEA characterisation, durability and polarisation protocols Corrosion, coatings, and inhibitors: polarisation resistance, EIS, and Tafel-style studies Electrocatalysis and electrodes: kinetics, stability, and impedance-derived charge-transfer analysis Choose ScienceGears (Australia) for local AU/NZ technical support and practical integration with electrochemical cells, electrodes, spectroelectrochemistry accessories (e.g., Raman-SEC cells), and broader energy test station workflows.
