MUX8-R2 Multiplexer
Multiplexer for 8 up to 128 cells
- Automatically switch between electrochemical cells
- Easy stacking with magnetic feet and top
- 4 different electrode or sensor configurations
- Daisy chain multiplexers, up to 128 channels!
The PalmSens series and the EmStat4X can be used to work with multiple working electrodes or a sensor array by means of a multiplexer.
The multiplexer switches between the working electrodes in the range of milliseconds.
- each MUX8-R2 multiplexer enables to work with up to eight 2- or 3- electrode systems.
- daisy chaining multiple MUX8-R2 boards (expansion up to 128 channels)
- all hardware settings are controlled by the software making it unnecessary to flick a physical switch
- LEDs to show which channel is selected
- allows to connect auxiliary input (like temperature sensor)

Connection options
The most selected connection option uses two double shielded D-Sub cables ending in 2 mm banana plugs. As alternatives we can provide a PCB with screw terminals, D-Sub cable ending in ferrules or Screen Printed Electrode Adapter. Each of these cables can be connected to 4 channels, if all 8 channels are used, two cables are needed.

AC1.GP. Electrochemical sensor with a working electrode of guaranteed purity
Read moreBasic amperometric three-electrode sensor with patented structure made by thick film technology.
Dimensions: 25.40 mm x 7.26 mm x 0.63 mm
WE material: gold, platinum, silver, copper, iron, nickel, cobalt, chromium, tantalum, irridium, rhenium, magnesium, palladium, zirconium and others
*Selection of sensor electrode materials other than those listed above is possible upon agreement with the customer.
The sensor is made on a corundum ceramic base. Working, reference and auxiliary electrodes are applied to this surface. Working, reference and auxiliary electrodes are made of different materials. At the end of the sensor there is a contact field that is connected to the active part by silver conductive paths that are covered with a dielectric protective layer. The working electrode of the sensor with a diameter of 2 mm is made of a material of guaranteed purity of up to 99.99 % depending on the selected material– standard layer thickness 0.0125 mm.
We also offer a working electrode made of polished gold AC1P.W*.R*, with homogenous surface with roughness less than 1 µm.
We also offer activated graphite sensors on customer request.

Two versions:
Sensit BT.SPE Sensit BT.SNS 
Sensor pitch 2.54 mm Cable length 40 cm Electrode connections RE, WE, CE Connectors 2 mm banana Allowed sensor thickness Between 0.1 mm and 0.8 mm Electrode connections RE, WE, WE2, CE Maximum sensor width 11 mm Dual-channel and Bipotentiostat
The Sensit BT.SPE can be used for running sequential measurements on two different Screen-Printed Electrodes (SPE’s) each with their own Reference, Counter and Working electrodes.
The second channel can also be used in Bipotentiostat mode, functioning as second Working Electrode versus the Reference and Counter electrode of channel 1. Both working electrodes are recorded simultaneously in the Bipotentiostat mode.
The Sensit BT.SNS has a lead connected to the WE of channel 2 and can be used out-of-the-box for BiPotentiostat measurements.
On-board data storage
The Sensit BT is equipped with 500 MB internal storage memory.
Save measurements on-board as a backup. Or pre-program the device with a script and use the trigger button to run and store measurements: no need to connect a PC or smartphone. Browse and transfer all internally stored measurements back to the PC easily using PSTrace for Windows.
