Catalog excerpts

The 2450-EC Electrochemistry Lab System is Keithley’s low cost alternative to traditional electrochemistry potentiostats. The 2450-EC brings speed, flexibility, and simplicity right to your fingertips. Its innovative graphical user interface (GUI) and advanced, capacitive touchscreen technology allow intuitive usage and minimize the learning curve to enable researchers, scientists, and students to learn faster, work smarter, and invent easier. The 2450-EC is a versatile instrument, particularly well-suited for research and development in fundamental electrochemical lab research, characterizing the next generation of materials and electrolytes, new energy storage devices, and faster, smaller sensors. • Lower cost alternative to potentiostats The Keithley 2450-EC Electrochemistry Lab System: A Low Cost Alternative to the Potentiostat • Perform Cyclic, Squarewave, or Galvanic Voltammetry, Chronoamperometry, and Chronopotentiometry While potentiostats are excellent instruments for electrochemistry applications, they typically lack any front panel display and control knobs, often are 2-quadrant systems only, and must be completely controlled by a computer with software that is not always open for users to customize tests beyond what the software can do. • Simplified user interface for faster test setup and analysis of results • Real-time plotting of voltammograms on the front panel • Analytical graph cursors for immediate analysis of results without the need for a PC • Create libraries of reusable, customizable experimental software with built-in open source scripting Keithley’s 2450-EC is a smart alternative as a DC/low frequency potentiostat. The 2450-EC has features that, in many cases, can perform as well as a potentiostat at lower cost including a wide range of voltages and currents for sourcing or measuring, nV / fA sensitivities, and high impedance sense leads with a typical input resistance of 50G ohms and only 1pA of input bias current, typically acceptable with a wide variety of reference electrodes. The 2450-EC can run internal application test scripts so electrochemistry meaurements can be run without the use of an external computer. Results (graphs) are immediately displayed right on the instrument front panel touchscreen. Connecting the 2450-EC to a 2-, 3-, or 4-electrode cell to perform the same tests as a potentiostat is simple with the included translation cable. Electrochemical Cell • Screen capture function allows copying test results from the display to reports Working Electrode Reference Electrode • Front panel input banana jacks; rear panel input triaxial connections Counter Electrode • Context-sensitive help function minimizes learning • Front-panel USB 2.0 memory I/O port for transferring data, test scripts, or test configurations The 2450-EC can be easily connected to a 3-electrode cell.

Test Applications The 2450-EC’s built-in open source scripting enables electrochemists, chemists, and materials scientists to create libraries of reusable, customizable experimental software for running tests including cyclic voltammetry, chronoamperometry, chronopotentiometry, and more. The following electrochemistry test scripts are loaded in the internal memory of the 2450-EC. • Cyclic Voltammetry: Potential is swept at a user programmable scan rate between two to four defined vertices while current is measured. Current is measured using an analog integration method. • Linear Sweep...
