EmStat3+ Blue (ES3P-BLUE)

EmStat Blue is a small USB and battery powered potentiostat with integrated Bluetooth. It is ideal for mobile sensor applications.

 

Product Description

EmStat Blue is a small and low cost potentiostat with research grade capabilities. It has eight current ranges from 1 nA to 100 mA (EmStat3+ Blue) full scale, with a minimum resolution of 1 pA. It provides the most relevant electroanalytical measurement techniques and is used with the PSTrace software or with PStouch for Android.

Standard included with an EmStat Blue:

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

Optional:

  • Samsung tablet for use with PStouch

Sensor cable with croc clips

 

Customization for (industrial) applications

EmStat Blue is ideal for customization because it has:

  • a Screen Printed Electrode (SPE) connector on the front for direct use with your electrodes
  • an extensive SDK for quick development of custom smartphone or tablet apps or PC software
  • an integrated Bluetooth radio and Li-Ion battery
  • commercially feasible prices for customization or re-branding at already low quantities

Techniques

The following techniques are supported by EmStat Blue.

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)
