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.

Hanging Platinum Drop Electrode
Read moreThe Hanging Platinum Drop Electrode (HPDE) is solid phase alanogy of HMDE.
The drop of liquid Pt at 2000 °C forms a drop of Pt. The surface of HPDE has nearly ideal surface which is impossible to obtain using polishing. HPDE has also spherical symmetry which enables mathematical treatment of its response.
The material is not toxic and it is chemically stable. The only disadvantage is HPDE cleaning, which can be, however, in some cases solved by carefull insertion of the electrode tip to the flame of an alcohol burner.
Thus HPDE can be used as reference electrode for complicated electrochemical studies, where it is necessary to distinguish the analytical signal from the signal generated by surface inhomogenities.Hanging platinum drop electrode (HPDE) is designed for measurements with thermostated cell TC4, TC5, TC6 and TC9.
