AC1. electrochemical sensor with a hydrophobic ring

Electrochemical sensor type AC1. with a hydrophobic ring – a hydrophobic layer is printed around the working electrode of the sensor (with a diameter of 1 or 2 mm), which ensures that the liquid applied to the working electrode of the sensor forms a drop and does not move outside to the reference and auxiliary electrodes (see the photograph below).

 

Such modification of the sensor is suitable, for example, before the next intended modification of only the working electrode of the sensor by the customer – for example, immobilization of a bioactive substance.

  • AC1P Electrochemical sensor

    Amperometric three-electrode sensor with patented structure type AC1 with polished working electrode made by thick film technology.  

    Dimensions: 25.4 x 7.26 x 0.63 mm

    WE material: Au

     

    The sensor is formed on a corundum ceramic base. On to this surface the working, the reference and the auxiliary electrodes are applied. Working electrode has homogenous surface with roughness less than 1 µm. 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.
