The EmStat4X delivers high performance in a small footprint. The EmStat4X is a small battery and USB-powered Potentiostat, Galvanostat, and optional Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The EmStat4X Low Range (LR) version is great for applications that require a low current range down to picoamps, like (bio)sensor research. The High Range (HR) version is very suitable for applications that need a maximum current of up to 200 mA. The EmStat4X is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.
The EmStat4X LR and HR features include:
Two versions
The EmStat4X comes in two different versions as below. Both versions can be configured with optional EIS/FRA up to 200 kHz. See specifications for a detailed comparison between the LR and HR.
Low Range: For lower currents and potentials (±30 mA / ±3 V applied / ±5 V compliance)
High Range: For higher currents and potentials (±200 mA / ±6 V applied / ±8 V compliance)
Techniques available with PSTrace Software (Included with instrument)
Stripping Modes: The voltametric and pulsed techniques can all be used in their stripping modes which are applied for (ultra-) trace analysis.
