Squidstat Venta
±20 A Potentiostat with EIS up to 1 MHz and 1% / 1° Accuracy at 0.01 mΩ
Squidstat Venta 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 Venta includes one 90 cm Working Electrode cable, one 90 cm Counter Electrode cable, one sense cable with Reference, Working Sense, Counter Sense connections, one USB cable, and one power cable to connect to a power outlet. The Squidstat User Interface software and unlimited remote technical support are included with purchase.
