Ossila Electrochemistry PC Software

Ossila Electrochemistry PC Software

Intuitive PC software for performing linear sweep and cyclic voltammetry, open circuit potential, and controlled potential electrolysis with the Ossila Potentiostat. Simply set your experimental parameters and press measure to start collecting data. When your measurement is finished, the software lets you export the results as a CSV file so that you are never locked into one ecosystem. Your settings are saved alongside your data and can be stored in the software so that you can quickly and easily repeat your measurement or perform similar scans.

Available to download from our website at any time. Future updates are provided at no extra cost.

Ossila Test Cell Chip

Ossila Test Cell Chip

The test cell chip simulates an electrochemical cell so that you can test your potentiostat under controlled conditions. The chip provides a different response (with three different maximum currents) depending on the direction of the scan. To perform a test, simply plug in your potentiostat, connect it to the cell, and take a cyclic voltammetry measurement using the electrochemistry software as normal. The resulting cyclic voltammogram can then be compared to the example in the product manual.

Electrochemical Cell and Electrodes (Optional)

Standard electrochemical cell

Standard electrochemical cell

Our electrochemical cell glassware features a screw-fit PTFE lid with three electrode holes to hold the working, reference, and counter electrodes in place and two gas holes for degassing. To set up your three electrode system, simply place your solution (containing the chemical of interest, an electrolyte, and a solvent) in the cell and then place the electrodes in the holes in the lid. The gas intakes can be used to bubble an inert gas such as nitrogen or argon through the solution to remove any oxygen, which could otherwise cause unwanted redox processes.

Included with the Potentiostat if purchased with a cell. Available separately for £190.

Platinum disk working electrode

Platinum disc working electrode

The working electrode is where the electrochemical reactions take place. We sell a range of different types of working electrodes, including gold disc electrodes, but platinium is the most commonly used material. Platinum is electrochemically inert so will not interfere with your measurements and is resistant to solvents, acids and oxidation.

Included with the Potentiostat if purchased with a cell. Available separately for £210.

Platinum wire counter electrode

Platinum wire counter electrode

99.99% purity platinum wire counter electrode in a polytetrafluoroethylene (PTFE) plastic body. Platinum is electrochemically inert and is resistant to oxidation, solvents, and acids, making it a popular choice of material for a counter electrode. Our platinum wire counter electrodes allow current to flow through your electrochemical cell without affecting your results.

Included with the Potentiostat if purchased with a cell. Available separately for £190.

Non-aqueous Ag/Ag+ reference electrode

Non-aqueous Ag/Ag+ or aqueous Ag/AgCl reference electrode

Non-aqueous Ag/Ag+ reference electrodes consist of a high quality silver wire, which is sealed with a ceramic frit junction for use with a 0.01 M silver nitrate of acetonitrile solution. The aqueous Ag/AgCl reference electrode features a silver wire coated with silver chloride with ceramic frit junction and is used for direct contact with saturated potassium chloride, typically 3M concentration in distilled water. The ceramic frit minimises any mixing of your reference solution and your studied solution while being porous enough to allow a complete circuit to be formed. Unlike in a two electrode system, using separate counter and reference electrodes allows you to control the potential between the working and reference probes while measuring the current between the working and counter probes.

Included with the Potentiostat if purchased with a cell. Available separately for £110.

Resources and Support

Cyclic Voltammetry Basics, Setup, and Applications Cyclic Voltammetry Basics, Setup, and Applications

Cyclic voltammetry is an electrochemical technique for measuring the current response of a redox active solution to a linearly cycled potential sweep between two or more set values.

Cyclic Voltammetry Applications and Uses Cyclic Voltammetry Applications and Uses

Cyclic voltammetry is a versatile electrochemical method with a range of different applications. In cyclic voltammetry, each successful forwards and backwards potential sweep produces a 'duck-shaped' plot known as a cyclic voltammogram.

Troubleshooting Cyclic Voltammetry and Voltammograms Troubleshooting Cyclic Voltammetry and Voltammograms

Cyclic voltammetry is a powerful and versatile electrochemical technique. With modern potentiostats and software packages, the method is relatively straight-forward to perform. Despite this apparent simplicity, there are still a number of things that can go wrong, particularly when setting up the electrochemical cell.

Potentiostat Working Principles and Fundamentals Potentiostat Working Principles and Fundamentals

Potentiostats are voltage sources that vary their output potential in response to changes in the resistance across the circuit.

Linear Sweep Voltammetry: Introduction and Applications Linear Sweep Voltammetry: Introduction and Applications

Linear sweep voltammetry (LSV) is a simple electrochemical technique. The method is similar to cyclic voltammetry, but rather than linearly cycling over the potential range in both directions, linear sweep voltammetry involves only a single linear sweep from the lower potential limit to the upper potential limit.

What is Voltammetry? Types and Applications What is Voltammetry? Types and Applications

Voltammetry is the study of the current response of a chemical under an applied potential difference. Voltammetry encompasses a number of different methods.

Introduction to Bulk Electrolysis Introduction to Bulk Electrolysis

Unlike many other electrochemical techniques, which are limited to the diffusion layer, bulk electrolysis (sometimes referred to just ‘electrolysis’) changes the composition of the bulk solution. Bulk electrolysis experiments aim to generate a quantitative conversion such that the amount of substrate consumed is directly proportional to the total consumed charge.

Spectroelectrochemistry (SEC) Techniques Spectroelectrochemistry (SEC) Techniques

Spectroelectrochemistry (SEC) is an experimental technique that combines electrochemistry and spectroscopy. While electrochemical experiments provide information on macroscopic properties like reaction rates, spectroscopic techniques give information on a molecular level, such as the structure of molecules and their electronic configuration.

View All Electrochemistry Resources

The field of electrochemistry is concerned with the relationship between electrical potential and chemical reactions. Broadly speaking, this includes processes where a chemical reaction results in an electrical change (such as in a battery) or when a non-spontaneous chemical reaction is triggered by a change in electrical potential (via electrolysis).
