  •  The corresponding polarographic and stripping modes for most voltammetric techniques are available. 

  •  The instrument can be used as regular potentiostat.

  • When it is used as bipotentiostat, the 2nd channel can be controlled at an independent constant potential, to scan or step at the same potential as the first channel. In case of CV, it can also scan wiZero resistance ammeter

  •  Floating (isolated from earth) or earth ground 

  •  Maximum potential: ±10 V for both channels 

  •  Maximum current: ± 250 mA continuous (sum of two current channels), ±350 mA peak 

  •  Compliance Voltage: ±13 V 

  •  Potentiostat rise time: < 1 us, 0.8 us typical 

  •  Potentiostat bandwidth (-3 dB): 1 MHz 

  •  Applied potential ranges: ±10 mV, ±50 mV, ±100 mV, ±650 mV, ±3.276 V, ±6.553 V, ±10 V 

  •  Applied potential resolution: 0.0015% of  potential range 

  •  Applied potential accuracy: ±1 mV,  ±0.01% of scale 

  •  Applied potential noise: < 10 uV rms 

  •  Measured current range: ±10 pA to ±0.25 A in 12 ranges 

  •  Measured current resolution: 0.0015% of  current range, minimum 0.3 fA
