Brand New for 2022! PalmSens’s new MultiEmstat4 builds on the success of the Emstat and MultiEmstat series.  This new multichannel potentiostat includes 8 x Emstat4’s in a single compact package and each module now includes EIS and galvanostat. The channels can be operated independently or in synchronised, multichannel experiments using PalmSens’s MultiTrace Software.  The system may also be used as a polypotentiostat: multiple WE’s vs one CE and RE.

Each channel is an independent Emstat4 potentiostat. Options are available for galvanic isolation (for “floating” operation. )  

The MultiEmstat4 is available in either 8 channel or 12 channel versions and each of those is available in either High Range (HR) or Low Range (LR) versions.  See comparison table below.


Voltammetric techniques:

  • Linear Sweep Voltammetry (LSV)
  • Cyclic Voltammetry (CV)

Amperometric techniques:

  • Chronoamperometry (CA)
  • Zero Resistance Amperometry (ZRA)
  • Chronocoulometry (CC)
  • Multiple Amperometry (MA)
  • Pulsed Amperometric Detection (PAD)

Galvanostatic Techniques:

  • Linear Sweep Poteniometry (LSP)
  • Chronopotentiometry (CP)
  • MultiStep Potentiometry (MP)
  • Open Circuit Potentiometry (OCP)


Pulsed techniques:

  • Differential Pulse Voltammetry (DPV)
  • Square Wave Voltammetry (SWV)
  • Normal Pulse Voltammetry (NPV)


  • Mixed Mode (MM)
  • Potentiostat / Galvanostatic Impedance Spectroscopy (EIS/GEIS)

Synchronizing channels in Synched mode

By enabling synchronization of channels and adjusting the setup of your cables, you can use the MultiEmStat4 as a polypotentiostat. This means you can use multiple working electrodes, one counter and one reference electrode in the same cell at the same time. Your working electrodes all perform the same measurement
