Squidstat Plus

±1 A Potentiostat with EIS up to 2 MHz and 1% / 2° Accuracy at 1 mΩ

Squidstat Plus Highlights:

  • Becomes a multichannel system by connecting more Squidstats to the same computer
  • Onboard memory (16 GB) backs up all data collected from experiments for failsafe recovery
  • Voltage/current setpoints, OCP mode, and sampling rates are adjustable in real time
  • Wide selection of prebuilt experiments are available, and the “Drag & Drop” experiment builder can quickly and easily make custom experiments – no coding skills necessary!


Each Squidstat Plus includes one 100 cm channel cable set, one USB cable, and one power supply with over 300 cm in length between the power outlet and potentiostat. The Squidstat User Interface software and unlimited remote technical support are included with purchase.
