Working Disk Electrode – PEEK body 6 mm dia., 70 mm long (redox.me)
This is a Standard Working Electrode in which a disk of electrode material (glassy carbon, gold, platinum, silver, boron-doped diamond, palladium, titanium, and copper) is embedded into the PEEK body by a compressed PTFE or PEEK sleeve. It well fits aqueous and organic solvent electrolyte requirements. If you need a different disk material, please contact us.
Application note
The disk electrode is immersed in the ion-conducting solution as a working electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the experiment, the electrode should be washed several times with ethanol or isopropanol. If the disk electrode was used as a current collector with other electrode material, or when there are visible traces of material absorption, it should be polished down to the mirror surface after the experiment is completed. Store the working disk electrode in the glass tube sealed with an O-ring (all included in the package). Instruction on maintenance is provided on the Electrode Polishing Kit product page.

Platinum Coated Titanium Mesh Electrode with Holder – set of 10 pcs (redox.me)
Read moreThe metal counter (auxiliary) electrode is provided in electrochemical cell as a current sink to shunt excess current away from the reference electrode. Platinum Coated Titanium Mesh Electrode is a cheap alternative to pure Platinum Electrodes like Platinum Gauze Electrode or Metal Wire Auxiliary Electrode. Platinum coating makes this counter electrode inert under the reaction conditions and provides catalytic properties. The electrode is installed in the Basic Sample Holder (1 pcs included in the set), which allows full immersion of the electrode in the electrolyte (wet Tantalum contact). It well fits aqueous and organic solvent electrolyte requirements. Electrode size is customizable.
Application note
The Platinum Coated Titanium Mesh Electrode is fully immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the Platinum Coated Titanium Mesh Electrode for a certain amount of time. After the process, the electrode should be washed several times with ethanol and dried under the nitrogen flow. Store the electrode in a dedicated compartment to avoid scratching. Discoloration may indicate the degradation (dissolution) of the Platinum layer and oxidation of Titanium mesh.
This electrode is used mainly in systems where there is a high risk of its contamination by organic or inorganic deposit during the electrochemical reaction. It is also a cheap replacement for pure Platinum electrode in electrodeposition processes.Specification

EmStat4 MUX (2-in-1: Potentiostat with integrated multiplexer)
Read moreGone 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.
More information could be found tought link:
https://www.palmsens.com/product/emstat4-mux/
- 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.

Nexus
Read moreBuilding on PalmSens’ legacy of providing top-tier solutions for accurate low-current measurements, Nexus delivers an ultra-low-noise performance that exceeds even our existing portable devices, while also supporting measurements up to 1 Ampere.

Versatile
Our high-end instrument, the Nexus, is a Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The Nexus has a large potential range (-12V to +12V) and current range (100 pA to 1 A) with a high resolution and low noise.
The research software PSTrace makes using the Nexus a breeze. The scripting language MethodSCRIPT gives a user full control when needed. Looking for a multi-channel instrument? Just stack multiple instruments on top of each other.

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.
