Custom and Modified Screen Printed Electrodes (SPE)
We offer our customers Modified and Custom Screen Printed Sensors based on their demands and needs, we will also recommend to the customer if there is a better option for their intended purposes.
Examples of possible Modified SPE Surfaces
Graphine, Streptavidin, Polyaniline and High-purity Materials.
High-purity material on WE
We can provide polished working electrode or insert a high-purity material on WE (99.9% or better).
The WE can be applied also by sputtering.
Materials of WE
We can offer you not only standard materials as Au/Pt, Au, Pt, Ag, C (carbon) but also glassy carbon, Ni, Cu, and other materials.
Special Active Surfaces
We can provide SPEs with Special Active Surfaces using Copper (Cu), Nickle (Ni), Magnesium (Mg), Bismuth (Bi) and Zirconium (Zr).
Sensor/device size
The Technological capabilities and our experience and knowledge enable us to produce devices from as small as 3 x 6 mm, up to as large as 150 x 1200 mm.

AC1 Dwe= 4 mm Electrochemical sensor
Read moreBasic 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.

Dimensions: 25.4 x 7.26 x 0.63 mm
Electrochemical measurements are very sensitive. Sometimes cables, connectors and their wetness can create the measurement errors. Testing sensor enables simple identification of electrochemical hardware error. The sensor has same geometry as AC1 type but its response produced by resistor. The response is stable and independent on chemistry. Testing sensor is formed on a corundum ceramic base. At the end of the sensor there is a contacting field which is connected with the SMD resistors by the silver conducting paths which are covered by a dielectric protection layer.
