The Keithley 2450EC Graphical Potentiostat, 200V, 1A, 20W brings speed, flexibility, and simplicity right to your fingertips. Its innovative graphical user interface (GUI) and advanced, capacitive touchscreen technology allow intuitive usage, minimizing the learning curve to enable researchers, scientists, and students to learn faster, work smarter, and invent easier. The Keithly 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.
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.
The Keithley 2450-EC includes 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 50 Gohms 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 are immediately displayed right on the instrument front panel touchscreen. Connecting the 2450-EC to a 2-, 3-, or 4-electrode cell is simple with the included translation cable.
Keithley 2450-EC can be easily connected to 3-electrode cell
Learn Faster; Work Smarter; Invent Easier
Unlike traditional potentiostats that lack a user-interface front panel to interact with, the 2450-EC features a five-inch, full-color, high resolution touchscreen that facilitates ease of use, and optimizes overall speed and productivity. Built-in, context-sensitive help enables intuitive operation and minimizes the need to review a separate manual. These capabilities, combined with its application versatility make the 2450-EC inherently easy to use for basic and advanced measurement applications, regardless of your experience level with electrochemistry instruments.
Convert Raw Data into Information
A full graphical plotting window converts raw data and displays it immediately as useful information, such as cyclic voltammograms. The touch screen interface makes it easy to observe, interact with, and explore measurements with "zoom and pinch" simplicity. By using the built-in graphing cursors, you can immediately analyze your data without a computer. All graphic screens can be saved to a USB thumb drive for incorporation into reports and journals. Using the graphical sheet view, test data can also be displayed in tabular form. The instrument supports exporting data to a spreadsheet for further analysis, dramatically improving productivity for research and development. This combination of high performance and high ease of use offers unparalleled insight into your test results.
The Keithley 2450-EC's built-in scripting language 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. This application can also be used to perform Linear Sweep Voltammetry.Open Circuit Potential: Measures the cell potential difference between two electrodes with high input impedance as a function of time.
Potential Pulse and Square Wave with Current Measure: The 2450-EC sources potential at programmable peak and base levels and the resulting current is recorded at the pulse peak level.
Current Pulse and Square Wave with Voltage Measure: The 2450-EC sources current at programmable peak and base levels and the resulting potential is recorded at the pulse peak level.
Chronoamperometry: The potential is stepped to a programmed value and the resulting current is measured as a function of time.
Chronopotentiometry: The current is stepped to a programmed value and the resulting potential is measured as a function of time.
In addition to pre-loaded test scripts, the built-in scripting language enables the user to create their own library of electrochemistry test scripts that can be modified as the test and measurements evolve.
The 2450-EC offers a highly flexible, four-quadrant voltage and current source/load coupled with precision voltage and current meters. When not used in potentiostat type applications, this all-in one instrument can be repurposed as a general lab instrument, including use as a:
- Precision power supply with V and I readback
- True current source
- Digital multimeter (DCV, DCI, ohms, and power with 6 1/2-digit resolution)
- Precision electronic load
- Trigger controller
Ease of Use Beyond the Touchscreen
In addition to its five-inch, color touchscreen, the 2450-EC front panel has many features that supplement its speed, userfriendliness, and learnability, including a USB 2.0 memory I/O port, a HELP key, a rotary navigation/control knob, a front/ rear input selector button, and banana jacks for basic bench applications. The USB 2.0 memory port supports easy data storing, saving instrument configurations, loading test scripts, and system upgrades. Plus, all front panel buttons are backlit to enhance visibility in low-light environments.
Comprehensive Built-in Connectivity
Rear panel access to rear-input triax connectors, remote control interfaces (GPIB, USB 2.0, and LXI/Ethernet), D-sub 9-pin digital I/O port (for internal/external trigger signals and handler control), instrument interlock control, and TSP-Link jacks enables easy configuration of multiple instrument test solutions and eliminates the need to invest in additional adapter accessories.
Free Instrument Control Start-up Software
The 2450-EC can be repurposed for applications beyond electrochemistry as a general purpose lab tool, e.g. I-V testing, leakage testing, battery charge/discharge profiling, etc. KickStart, Keithley's instrument control non-programming start-up software, lets users start taking measurements in minutes for typical current versus voltage applications. In most cases, users merely need to make quick measurements, graph the data, and store the data to disk to perform analysis in software environments such as Excel.
