Electrochemistry lab systems cover many experiments

The traditional approach to electrochemistry testing involves potentiostat instrumentation and vendor-supplied software that is typically not customisable. The Keithley solutions bring advantages, including a lower purchase price and cost of ownership, customisable software, and simple operation with the ability to run experiments, make measurements, and generate voltammogram plot results directly on the instruments’ touchscreen display.

With gestural ‘pinch and zoom’ on the graphical display, users can quickly analyse the results and make quick research and design decisions. Potentiostats lack front panel controls and require a separate PC to set up and run experiments.

Electrochemists, chemists, and other scientists use electrical measurement techniques to study chemical reactions and dynamics. Keithley’s Electrochemistry Lab Systems are versatile instruments that can source and measure voltage or current and can be used to compare results to parameters for voltammetry experiments or over time for chronoamperometry experiments.

These instruments are 4-quadrant instruments that can both source power and sink power. Typical potentiostats are 2-quadrant, which limits their use as a general purpose instrument beyond electrochemistry applications.

In contrast the 2450-EC and 2460-EC can be repurposed as a general use lab tool for such applications as I-V testing, leakage testing, and battery charge/discharge profiling.

Chemistry and electrochemistry researchers are pushing the limits of what’s possible with the pre-programmed, non-modifiable tests furnished with most potentiostats. In contrast, the 2450-EC and 2460-EC provide nearly limitless flexibility through the use of an embedded open-source Test Script Processor (TSP) system that enables researchers to create their own library of electrochemistry test scripts that can be modified as tests and measurements evolve.

The 2450-EC and 2460-EC are housed in a compact package that enables easy transport around a lab, without the need for a cart to transport a much larger potentiostat and computer.

The 2450-EC can source and measure up to 200V or 1A, with source/sink power up to 22W; the 2460-EC can source and measure up to 100V or 7A, with source/sink power up to 100 watts.

These instruments offer excellent measurement sensitivity - as low as 10nV and 10fA, source and measure ranges as low as 20mV and 10nA, and 0.012% basic measurement accuracy with 6.5 digit resolution. Each instrument features a high-resolution five inch touchscreen display for intuitive usage and minimised learning curve.
