Description

EmStat3 is a small and low cost potentiostat with research grade capabilities. It has eight current ranges from 1 nA to 100 mA (EmStat3+) full scale, with a minimum resolution of 1 pA. It provides the most relevant electroanalytical measurement techniques. Its price makes it a popular choice for educational purposes.

Standard included with an EmStat3/3+:

  • Rugged carrying case
  • High quality, double shielded cell cable with
    2 mm banana connectors for Working, Counter, Reference, Sense (EmStat3+) and Ground
  • Crocodile clips
  • Dummy cell
  • USB cable
  • PSTrace software for Windows

Sensor cable with croc clips

Techniques

Voltammetric techniques

  • Linear Sweep Voltammetry (LSV)
  • Cyclic Voltammetry (CV)

Pulsed techniques

  • Differential Pulse Voltammetry (DPV)
  • Square Wave Voltammetry (SWV)
  • Normal Pulse Voltammetry (NPV)

These methods can all be used in their stripping modes which are applied for (ultra-) trace analysis.

Amperometric techniques

  • Chronoamperometry (CA)
  • Zero Resistance Amperometry (ZRA)
  • Chronocoulometry (CC)
  • MultiStep Amperometry (MA)
  • Pulsed Amperometric Detection (PAD)
  • Multiple-Pulse Amperometric Detection (MPAD)

Galvanostatic techniques

  • Open Circuit Potentiometry (OCP)
