Integrated Potentiostat System

The ER466 Integrated Potentiostat System is the most popular potentiostat from Edaq, 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).

Voltammetric techniques are performed with EChem software. Constant potential, or current, experiments are performed with Chart software running under Windows.

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).


  • Current ranges (and resolution):
         100 mA   (3.13 µA)          50 mA   (1.56 µA)         20 mA   (625 nA)
         10 mA   (313 nA)             5 mA  (156 nA)             2 mA   (62.5 nA)
         1 mA   (31.3 nA)              500 nA  (15.6 nA)         200 µA   (6.25 nA)
         100 µA   (3.13 nA)           50 µA  (1.56 nA)           20 µA   (625 pA)
         10 µA   (313 pA)              5 µA  (156 pA)              2 µA   (62.5 pA)
         1 µA   (31.3 pA)               500 nA  (15.6 pA)         200 nA   (6.25 pA)
         100 nA   (3.13 pA)           50 nA  (1.56 pA)           20 nA   (625 fA)
