Description

The sensor is formed on a corundum ceramic base. On this surface the working, the reference and the counter electrodes are applied. The working and the counter electrodes can be made of variety of materials. A bio-chemically active substance can be immobilized on the working electrode of the sensor to create a biosensor. 

The Working and Counter electrode can be made of:

  • W1 Gold
  • W2 Platinum
  • W3 Silver
  • W4 Carbon
  • WS Gold Platinum-alloy

The reference electrode can be made of three different materials:

  • R1 Ag / AgCl mixed – a nice basic reference electrode
  • R2 Ag covered with AgCl – shows a higher stability
  • RS Ag – these give a stable potential in chloride solution but can also be used a pseudo reference electrode

Working electrode diameter

  • 1mm Standard diameter
  • 2mm Larger working electrode

Electrode naming pattern

  • The electrodes are named in the pattern AC1.Wn.Rm with n and m being 1, 2, 3, 4 or S.

Dimensions

  • 25.4 x 7.26 x 0.63 mm.
