High Current Potentiostat

High Current Potentiostat System

The ER467 Potentiostat System is 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.

The ER467 can be purchased as:

• ER467E: Integrated Potentiostat with EChem software for voltammetric techniques.
• ER467C: Integrated Potentiostat with Chart and Scope software for constant potential and constant current experiments.
• ER467CE: 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 1 amp 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.

The ER467 is 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).
