EmStat4 MUX

Description

The EmStat4 MUX is a powerful potentiostat, galvanostat and impedance analyzer and supports all popular electrochemical techniques. Its 8 channels allow for sequential measurements, for example eight Screen-printed electrodes, or eight working electrodes in eight different cells. The instrument’s measurements can be highly customized using MethodSCRIPT. The 4 different cell connections available allow for many different setups. When the measurements are finished, you can easily save your results in PSTrace, or export your results to Excel.

Two modes of operation

Consecutive mode: this mode switches channel when a complete measurement has finished
Alternate mode: this mode switches all activated channels within the specified time interval of a measurement.

In both modes the unselected Working Electrodes can either be left floating or switched to Ground to keep the specified voltage.

Supports a 2-, 3- or 4-electrode setup

Connect four electrodes per channel by using the Sense Leads.
Or connect only three electrodes per channel by internally connecting all Sense electrodes to the Working Electodes in software.
Do you need to connect only two electrodes per channel? Combine the reference and counter electrode physically on the cable, or with a single click on the PSTrace software.

8 to 128 channels

Is 8 channels not enough? If more channels are required, one or more MUX-R2 can be stacked to the EmStat4 MUX for a total of up to 128 channels.

PSTrace

PSTrace for Windows provides support for all techniques and device functionalities. It has three modes; the Scientific mode which allows you to run all the techniques our instruments have to offer, and two dedicated modes for Corrosion analysis and the Analytical Mode. With a smooth simple interface, showing only the applicable controls, PSTrace is suitable for all levels of user experience. Functions include:

Direct validation of method parameters
Equivalent Circuit Fitting
Automated peak search
Scripting for running an automated sequence of measurements
Open data in Origin and Excel with one click of a button
Browse measurements on instrument’s internal storage

More information about PSTrace There are four ways to connect your sensor. These sensor connections are quoted separately.

Option A: Double shielded sensor cables with 2 mm banana connectors. The 2 mm banana connectors are compatible with standard croc clips (they will be included in the quotation as optional).
Option B: High-density cable that terminates in ferrules
Option C: Connection (Screw) Terminal to assemble your own wires.
Option D: Screen Printed Electrode Connector

Each of these connection options can be used to connect 4 channels. When you add the EmStatMUX8 in the quotation basket we will make sure to include two units of the selected connection option so you can connect all 8 channels to the electrochemical cells.
