EA163  Potentiostat

EA163 Potentiostat
EA163 Potentiostat
  • Modular potentiostat
  • 4 modes: potentiostat, galvanostat, ammeter and voltmeter

Replaced by EA165 in December 2017

EA165 has similar specification but with max current extended to 400mA



This modular potentiostat is perfect for cyclic voltammetry and electroanalytical chemistry, and can use two (working and counter), or three (working, auxiliary and reference) electrodes. It can also operate as a galvanostat, ZRA (zero resistance ammeter), and high impedance voltmeter. It must be used together with any e-corder model.

The bandwidth of the EA163 is 100 kHz and so it is suitable for use with the Z100 Electrochemical Impedance Analyzer.

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

Note that the EA163 Potentiostat supersedes earlier models (EA161 and EA160) in this series.
