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.

FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring
The flow cell with integrated stirring and reduced hydrodynamic noise is designed for the determination of single analyte using one miniature ion-selective electrode (ISE) and one miniature reference electrode with a diameter of 6 mm and length of 60 mm.

Rotation speed of integrated stirrer: 10-4000 rmp.

Miniature ion-selective electrodes and reference electrode were designed for integration into the flow cell for determination of Cl-, K+, Ca2+ and Na+ ions.

In flow mode, the system can operate automatically. The speed of the integrated stirrer can also be controlled by applying the corresponding voltage to the motor, connected to a stabilized source.

The flow cell with one selected ISE can be used for:

Automatic or semi-automatic measurement of concentration of Cl-, K+, Ca2+ and Na+ ions in various solutions (following prior calibration)

For continuous measurement of changes in concentration of Cl-, K+, Ca2+ and Na+ ions.

* For this product, we recommend our customers use the Training Service from BVT.
