EmStat4 MUX (2-in-1: Potentiostat with integrated multiplexer)
Gone are the days with too many cables. With the EmStat4 MUX you have a potentiostat and a multiplexer in one! 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.

Integrated 8-channel multiplexer

Supports 2-, 3- and 4-electrode setup using Sense Lead

Potential range: ± 3V

Compliance voltage: ± 5V

Current ranges: 1 nA – 10 mA

Maximum current: ± 30 mA

FRA / EIS up to 200 kHz

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.

Script your experiments!

Via the script window of PSTrace it is possible to perform a different experiment on each of the channels sequentially. Alternatively, you can use MethodSCRIPT to fully customize your measurements per channel.

Multichannel or Multiplexer?

To make it easier for you to decide, if a multiplexer or a multichannel device is more suitable for your application, we have created a short explanation of multiplexers and multichannels.

potentiostat with integrated 8 channel multiplexer

potential range: ± 3V or ± 4V

compliance voltage: ± 5V or ± 8V

current ranges: 1 nA – 100 mA

maximum current: ± 100 mA

S2 and BiPot

Nexus includes a Second Sense lead (S2) and an optional BiPotentiostat (BiPot) module.

S2 – Additional voltage (potential) measurement point

BiPot – Independent second working electrode for simultaneous current measurement

These two features are independent and serve distinct purposes:

S2 (Second Sense Lead)
S2 acts as an additional voltage-sensing input, with the same specifications as the main reference electrode. It measures the potential at a specific point in the cell and, because the current at that point is known, it can also be used to calculate impedance.

BiPot (BiPotentiostat Module)
The BiPot module introduces a second working electrode (WE2), operating versus the same reference and counter electrodes as the main channel. In BiPotentiostat mode, both working electrodes (WE1 and WE2) are recorded simultaneously. WE2 operates in potentiostatic mode, meaning it can independently control its potential and measure its current.
