FC3.TL.* LED Flow Cell

The flow cell enables the use of Screen printed sensors in a flow through arrangement for spectroelectrochemical measurements1,2.


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.

FC3.TL.* Data Sheet

Effect of flow rate

In the graph below, we can see the effect of the flow rate (from 1024 microliters/min to 4 microliters/min) of the carrier liquid (physiological solution) on the response of the glucose biosensor AC1.GOD enclosed in a flow cell. Physiological solution (carrier and washing liquid) was fed into the flow cell by a high-pressure pump.

The monitored analyte (1 mM glucose solution) was fed to the biosensor through a filling loop.

It can be seen from the graph that at lower flow rates, the peak corresponding to the response of the AC1.GOD biosensor to the analyte (1 mM glucose solution) broadens.

  • WI Wash Instrument for FC

    Washing instrument for flow cells FC2, FC3 and FC4.


    Flow cells FC2, FC3 and FC4 can be fouled by buffer salts, standard or sample substances especially in the tubing that brings measured liquid to the sensor.

    The salts embed namely in the edges of drilled openings. It causes decrease of the flow area, thereby flow rate. These negative influences decrease the signal and measurement reliability. Most frequently it happens when high salt concentration solutions or solutions with impurities are used. The flows cell can be washed by pressured water using syringe.

  • AC1 Electrochemical sensor

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

    Dimensions: 25.4 x 7.26 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) is used as the temperature sensor.
