MultiEmStat4

The MultiEmStat4 is a compact Potentiostat, Galvanostat, and optional Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS) with 8 or 12 channels. The MultiEmStat4 comes in two versions; the Low Range version is great for applications that require a low current range down to 1 nA, whereas the High Range version is very suitable for applications that need a maximum current of 200 mA.

The MultiEmStat4 is controlled with MultiTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.

Available with 8 or 12 channels
FRA / EIS: 10 μHz up to 200 kHz
Potential range: ±3 V (LR) or ±6 V (HR)
Max. current: ±30 mA (LR) or ±200 mA (HR)

Always a backup

The MultiEmStat4 is equipped with 500 MB internal storage memory on each channel for storing your measurements as a backup. All internally stored measurements can be browsed and transferred back to the PC easily using the MultiTrace software. Your data is always with your instrument wherever you take it.

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.

Specifications

The MultiEmStat4M is available in two versions: the LR (Low Range) and HR (High Range) version.
