ER466  Integrated Potentiostat System

ER466 Integrated Potentiostat System
ER466 Integrated Potentiostat System
  • Ideal for cyclic voltammetry, linear sweep and pulse techniques
  • Potentiostat, galvanostat, ammeter and voltmeter modes
  • Maximum 100 mA and ±10 V
  • Expandable using isoPod amplifiers
  • High accuracy 


The ER466 Integrated Potentiostat System is our most popular potentiostat model, being ideal for cyclic, linear sweep, and most analytical pulse voltammetric experiments, either in the research or teaching laboratory. It also functions as a galvanostat, ZRA (zero resistance ammeter), and high impedance voltmeter (electrometer). Connection to a computer is via a USB cable.

A full list of electrochemistry techniques availabe can be seen here.

The Integrated Potentiostat is normally sold as part of the EChem Startup System, which includes the software (EChem, Chart and Scope) and the electrode kit. It can also be purchased as:

  • ER466E: Integrated Potentiostat with EChem software for voltammetric techniques.
  • ER466C: Integrated Potentiostat with Chart and Scope software for constant potential and constant current experiments.
  • ER466CE: Integrated Potentiostat with EChem, Chart and Scope software.

Two additional, general purpose, input channels are available that can be used for recording signals from other devices (temperature, pressure, quartz crystal microbalance, light intensity etc) along with the current and potential signals of the potentiostat, all within a compact footprint to save bench space.

Current signal sensitivity ranges from sub nanoamp up to 100 mA which support a wide range of applications.

Voltage-clamp type experiments can be performed on tethered membrane systems with a tethaPatch for studies of ion channels using Scope and Chart software.

With the addition of an EA167 Dual Reference Adaptor, the potentiostat becomes a 4-electrode system with one working, one counter, and two reference electrodes for the measurement of currents across:
  • membranes (4-electrode voltage clamp), or
  • the interface between two immiscible electrolyte solutions (ITES).
