AC1 Dwe= 4 mm Electrochemical sensor

Basic amperometric three-electrode sensor with patented structure made by thick film technology.

 Dimensions: 38.10 mm after breaking off (25.40 mm) x 7.26 mm x 0.63 mm

WE material: Au/Pt, Au, Pt, Ag, C

 

The sensor is formed on a corundum ceramic base. On to this surface the working, the reference and the auxiliary electrodes are applied. The working and the auxiliary electrodes are made of variety of materials. At the end of the sensor there is a contacting field which is connected with the active part by the silver conducting paths which are covered by a dielectric protection layer.

 

A bio-chemically active substance can be immobilised on the working electrode of the sensor to create a biosensor. All sensors can be equipped with heating and temperature sensing elements. Thermistor (must be calibrated) or Pt 1000 (the response corresponds to the ISO standard) can be used as the temperature sensor. The sensor is equipped with handling part which enables safe manipulation without contamination of active area.

 

The handling part can be broken off and sensor can be inserted in the standard BVT flow cells.

 

 

 

We also offer:

  • working electrode made of polished gold (WE diameter 1 or 2 mm) – sensor type: AC1P.W*.R*, with homogenous surface with roughness less than 1 µm
  • working electrode made of a material of guaranteed purity of up to 99.99 % (WE diameter 2 mm) – sensor type: AC1.GP

We also offer activated graphite sensors on customer request.

  • FC2.TL.* PMMA Flow Cell

    The flow cell enables the use of Screen printed sensors in a flow through arrangement.

     

    The flow cell is suitable for sensors of type AC1, AC2, CC1, CC2 and CC3.

     

    The Screen printed sensor is inserted into the slit of cell and tightened by closing of the door.  The cell ensures the wall-jet flow around the working electrode and it is optimised so that no air bubbles cumulate in the cell. The cell contains also the contact and output cable.

     

    With the sensors enclosed in a flow cell, it is possible to measure semi-automatically or automatically using a pump or liquid switch for sample supply. Under such conditions, maximum measurement reproducibility is ensured.
