The Princeton Applied Research PARSTAT 2273 offers compliance voltage up to ±100 V
(available at the counter electrode), ±10-V scan ranges, a ±2-A current range, the ability to make
electrochemical impedance spectroscopy (EIS) measurements from 10 µHz to 1 MHz, and a
design that will sustain long-term, heavy-load operation. The 2273 connects to your PC or laptop
via Universal Serial Bus (USB), and uses one of our Electrochemistry PowerSuite™ family of
electrochemistry software modules — there are no user controls on the instrument itself.
Calibration, operation, and experimental procedures are covered in the Electrochemistry
PowerSuite HTML Help Manual, available on the software’s

1.1. Applications
Research Electrochemistry
— From determining the kinetics of an electron-transfer process,
to developing new and improved materials via unique electrodeposition or electrosynthesis
techniques, the PARSTAT 2273 was designed with the flexibility and capability required by
today's electrochemical researcher. Whether you are measuring a microelectrode, rotating disk
electrode, mercury electrode, or quartz crystal resonator, the 2273 supports the wide array of
electrodes used in a modern electrochemistry research lab.
Corrosion
— The 2273 is ideal for corrosion research. Whether you are measuring rebar in
concrete or titanium in Ringer's solution, the 2273 was designed to address your application.
Our PowerCORR™ Corrosion Measurement Software and PowerSINE EIS package
complement the 2273's impressive specifications to create the ultimate tool for any corrosion
lab. Are you working with large electrodes or resistive media? The 2273's 100 V compliance
voltage takes care of that. Studying a new corrosion inhibitor or coating technology? Femtoamp
current resolutions and >10

input impedance make even the toughest EIS measurements
seem routine.
Sensors
— For potentiometric sensors (such as ion-selective electrodes and coated wire
electrodes) and amperometric sensors (gas sensors, thin film microelectrodes, and chemically
modified electrodes), the 2273 provides current sensitivities that can surpass the requirements
of the most demanding measurement parameters, with a pA current range and fA resolution.
High compliance voltage allows for the growth of thin film electrodes and nanodeposition.
Biosensor development and analysis relies on techniques that are contained within the
PowerCV

cyclic voltammetry, PowerSTEP
®
chronoamperomtry/chronopotentiometry, and
PowerPULSE™ electroanalytical software packages.
Fuel Cells and Batteries
— For many years, Princeton Applied Research potentiostats/
galvanostats have been used in the development of new energy sources. From the early stages
of battery development to the charge/discharge experiments on the final product, the 2273 has
the current measurement range to address the challenges posed in developing the next
generation of batteries. Fuel cells offer a cleaner energy source for the future, and the 2273
helps bring that technology to market: Use EIS to examine the impedance of the PEM at
different humidity levels, perform I/V curves on solid oxide fuel cells (SOFCs), or run CVs on
