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.

SIRE Sensor Cell Set (Sensor with Injectable Recognition Element)
Read moreThe SIRE Sensor Cell Set consists of a sensor with an integrated non-removable specialised chamber.
The set also contains a syringe which will allow the injection of the recognition element (Enzyme).
The SIRE Sensor Cell uses the concept of soluble enzymes into a reaction chamber separated from the sample by a semi permeable dialysis membrane. The analyte (for example maltose), enters into the reaction chamber by diffusion. The analyte reacts with the recognition enzymes creating H2O2 which is oxidized on a screen printed Pt electrode. The current corresponds to the amount of analyte.* For this product, we recommend our customers use the Training Service from BVT.

Mini Rotating Disk Electrode
Read moreThe Mini Rotating disk electrode (Mini RDE) in general enables defined mass transfer towards electrode surface.
The Mini RDE consists of the body of the RDE (motor) with 6 pcs of interchangeable electrode tips.
The device is equipped by control electronics and SW and powered by USB connection with PC.
Rotational speed of Mini RDE is 10 – 1300 rpm.RDE is suitable for measurements in glass cells of type TC4, TC5, TC6 and TC7. During measuring with RDE
in a classic three-electrode connection, it is advisable to use a classic reference RCEc.R* and auxiliary electrode ACEc.* For this product, we recommend our customers use the Training Service from BVT.
