The Squidstat Plus is a single channel combined potentiostat galvanostat with FRA and EIS capabilities. It is capable of applying ±10V of potential to a sample or ±1A of current. EIS measurements can be made within the 10 µHz - 2 MHz frequency range. It has 5 alligator clip cables: 2 are lead used to apply potential and current, one attaches to the working electrode and the other to counter electrode; 2 are sense leads used for measuring potential and current at the working and counter electrodes; the fifth is a reference electrode, used to determine what potential will be assigned to 0 V. | |||

The Squidstat Plus is a single channel combined potentiostat galvanostat with FRA and EIS capabilities. It is capable of applying ±10V of potential to a sample or ±1A of current. EIS measurements can be made within the 10 µHz - 2 MHz frequency range. It has 5 alligator clip cables: 2 are lead used to apply potential and current, one attaches to the working electrode and the other to counter electrode; 2 are sense leads used for measuring potential and current at the working and counter electrodes; the fifth is a reference electrode, used to determine what potential will be assigned to 0 V.
Galvanostat
A galvanostat applies a potential to an electrical circuit or cell and measures a response in the current.
Potentiostat
A potentiostat applies a current to an electrical cell or circuit and measures the resulting response in potential.
