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.

  • 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.
