EmStat+ (ES3P-USB)

The EmStat USB powered potentiostats are the smallest research grade electrochemical interfaces available on the market.
The devices are general purpose potentiostats but are also highly suitable for embedded use in applications.



Product Description

EmStat 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 EmStat:

  • high quality, double shielded cell cable
  • 2 mm banana connectors for working, counter, reference electrode and ground
  • mini-crocodile clips
  • USB cable
  • software

Sensor cable with croc clips



The following techniques are supported by EmStat.

Voltammetric techniques:

  • Linear sweep voltammetry (LSV)
  • Differential pulse voltammetry (DPV)
  • Square wave voltammetry (SWV)
  • Normal pulse voltammetry (NPV)
  • Cyclic voltammetry (CV)

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

Techniques as a function of time:

  • Chronoamperometry (CA)
  • Pulsed amperometric detection (PAD)
  • Multiple pulse amperometry (MPAD)
  • Open circuit potentiometry (OCP)
  • Multistep amperometry (MA)
