MultiEmStat3 & 3+: 4, 8 or 12 channels, now up to 100mA per channel

 

The PalmSens MultiEmStat multi channel potentiostats are designed for the most demanding users who want quality and high productivity without compromising on cost.

The MultiEmStat is a versatile multipotentiostat with 4, 8 or 12 independant EmStat potentiostats.

The channels can perform experiments independantly of each other, and each channel is capable of the full range of techniques that an EmStat can offer.

The MultiEmStat has a single USB connection and is controlled by a software application called MultiTrace.

Each poteniostat has 8 (EmStat3) or 9 (EmStat3+) current ranges: 1nA to 10mA/100mA with a resolution of 1pA at the lowest current range and can automatically select the optimal current range.

 

MultiEmStat supported techniques

Voltammetric techniques:

  • Linear Sweep Voltammetry (LSV)
  • Differential Pulse Voltammetry (DPV)
  • Square Wave Voltammetry (SWV)
  • Normal Pulse Voltammetry (NPV)
  • Cyclic Voltammetry (CV)

Technique as a function of time:

  • Amperometric Detection (AD) (Chronoamperometry)
  • Pulsed Amperometric Detection (PAD)
  • Multiple Pulse Amperometry (MPAD)
  • Open Circuit Potentiometry (OCP)
  • Multistep Amperometry (MA)
