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:

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

Sensor cable with croc clips

Optional:

  • Samsung tablet for use with PStouch

current ranges
A potentiostat measures current. For optimal precision, the range between which currents are measured is split into multiple current ranges. A current range defines the maximum current a potentiostat can measure in a certain range. This means it will also determine the resolution, because the number of bits or rather states is fixed, while the current range is variable.
1 nA to 10 mA (8 ranges) 1 nA to 100 mA (9 ranges)
maximum current ± 20 mA typical
and ± 15 mA minimum
± 100 mA typical

The current is measured using a zero resistance ammeter (ZRA).

Current
current resolution 0.1% of current range, 1 pA at lowest current range
current accuracy
The current accuracy describes how close to the real values your measured current is.
(deviation)
≤ 1 %of current range at 1 nA
≤ 0.5 % at 10 nA
≤ 0.2 % at 100 nA to 100 uA
≤ 0.5 % at 1 mA, 10 mA and 100 mA
all with max. 0.2 % offset error
electrometer amplifier input
The amplifier input resistance of the amplifier in the electrometer determines the load that the amplifier places on the source of the signal being fed into it. Ideally the resistance is infinite, and the load to be zero to not to influence your measurement.
