2450-EC
Electrochemistry Lab System
The 2450-EC Electrochemistry Lab
System is Keithley’s low cost alternative
to traditional electrochemistry potentio-
stats. The 2450-EC brings speed, flexibil-
ity, and simplicity right to your fingertips.
Its innovative graphical user interface
(GUI) and advanced, capacitive touch-
screen 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 instru-
ment, particularly well-suited for research
and development in fundamental electro-
chemical lab research, characterizing the
next generation of materials and electro-
lytes, new energy storage devices, and
faster, smaller sensors.

The Keithley 2450-EC Electrochemistry Lab System:
A Low Cost Alternative to the Potentiostat
While potentiostats are excellent instruments for electrochemistry applications, they
typically lack any front panel display and control knobs, often are 2-quadrant sys-
tems 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.
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 com-
puter. 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.

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 capa-
bilities 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 electrochem-
istry instruments.

Test Applications
Electrochemistry Lab System
The 2450-EC’s built-in open source scripting enables electro-
chemists, chemists, and materials scientists to create libraries
of reusable, customizable experimental software for running
tests including cyclic voltammetry, chronoamperometry, chro-
nopotentiometry, 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 Voltammetry:
Potential is swept at a user
programmable scan rate between two defined points while
current is measured.
•
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 while current is recorded at a user-defined
position on the pulse peak level.
•
Current Pulse and Square Wave with Voltage Measure:
The 2450-EC sources current at programmable peak and
base levels while potential is recorded at a user-defined
position on the pulse peak level.
•
Chronoamperometry:
The potential is stepped to a
programmed value while the resulting current is measured
as a function of time.
•
Chronopotentiometry:
The current is stepped to a
programmed value while the resulting potential is measured
as a function of time.
In addition to pre-loaded test scripts, the built-in open source
scripting language enables the user to create their own library
of electrochemistry test scripts that can be modified as the
test and measurements evolve.
