1. Overview
Ossila's Potentiostat is low-cost and easy-to-use system for performing cyclic voltammetry
measurements. Cyclic voltammetry is one of the most widely used electrochemical techniques,
providing important information about materials including:
•Reduction and oxidation potentials
•Reversibility of a reaction
•Electron transfer kinetics
•Energy levels of semiconducting polymers
The Potentiostat is capable of outputting potentials up 5 V, and measuring currents as low as 10
nA, allowing for a wide range of material characterisation. The easy-to-use PC software included
with the system allows anyone to perform the measurement.

9. Operation
9.1 Taking a Measurement
1. Add your appropriate electrolyte solution into the electrochemical cell.
2. Place the lid on the cell and insert the working, counter, and reference electrodes.

Potentiostat User Manual
Ossila.com 12 Ossila Limited © 2020
3. Use the banana cables and crocodile clips to connect the sockets on the front of the
Potentiostat to the appropriate electrodes.
I. The red socket connects to the working electrode.
II. The black socket connects to the counter electrode.
III. The blue socket connects to the reference electrode.
4. Start the Ossila Cyclic Voltammetry software. The window shown in Figure 9.2 will open.
5. Enter the appropriate settings for your experiment into the software (explained in more
detail in Section 9.2).
6. Click the ‘Measure’ button.
I. The system will sweep the potential between the working electrode and reference
electrode, whilst measuring the current between the working electrode and
counter electrode, in the follow steps:
Start Potential →Potential Vertex 1 →Potential Vertex 2 →Start Potential
II. This will be repeated for the specified number of cycles.
7. If ‘Save After Measurement’is turned on, the measurement data and settings will be saved
once the sweep has completed.
