PalmSens 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.
