eDAQ has released the ER467 High Current Potentiostat. It measures from sub nanoamp up to 1 amp, suitable for a wide range of applications. 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).
