Keithley Potentiostats

The 2450-EC, 2460-EC, and 2461-EC Potentiostats are flexible, low-cost, and ideal for research and development in fundamental electrochemical lab research, characterizing next generation materials and electrolytes, new energy storage devices, and faster, smaller sensors. The potentiostats include everything you need for electrochemistry testing, including cyclic, squarewave, or galvanic voltammetry, chronoamperometry, and chronopotentiometry.  
2450-EC, 2460-EC and 2461-EC have been discontinued. However, the electrochemistry testing functionality is still available through purchasing the EC-UPGRADE option to any 2450, 2460 or 2461 instrument.
