831 KF Coulometer with generator electrode with diaphragm

831 KF Coulometer with generator electrode with diaphragm
Beställningsnummer: 2.831.0010

Inexpensive coulometer including titration cell and generator electrode with diaphragm for water content determination down to trace levels.

This coulometer has become indispensable in many laboratories thanks to its reliability, its backlit graphical display, the multi-language dialog and the simplicity of its operation. The clear display provides information regarding the relevant titration parameters and unambiguous indication of the progress of the titration in the form of a curve showing µg water over time.

Recommended measuring range: 10 µg - 200 mg absolute water

  • 860 KF Thermoprep
    2.860.0010
    860 KF Thermoprep

    The 860 KF Thermoprep is designed for thermal sample preparation in Karl Fischer titration.

    Numerous substances cannot be analysed by direct Karl Fischer titration as they are not soluble, react with the Karl Fischer reagent or release their water only very slowly or not until heated to high temperatures. Using tightly sealed sample vials, the sample is inserted in the oven. The samples can be subsequently analysed by any volumetric or coulometric KF titrator.
