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
