If the reagents continue to run in from the storage bottle after the actual dosage process has ended, position the
bottle at lower level than the titration vessel. If the reagents continue to run in from the storage bottle between the
dosage process and the siphon off process, please wait a few seconds between the changes.
We recommend to remove the glass adaptor with the dosing and exhaust hose after adding the KF-
anolyte and to close the ground-in opening with the provided die glass stopper NS 14.5.
2.5 Filling the Titration Vessel
Fill the titration vessel approx. up to a half with anolyte that are suitable for the respective application using a
funnel (Module 1 and 3). You can even use the pump for modules 2 and 4. If you use a generator electrode with
diaphragm (included in delivery with module 3 and 4), it is necessary to fill an ampoule with catholyte into the
generator electrode. Here, please use a syringe with needle:

2.6 Switch on Device, First Conditioning
Set the stirring speed at the TM 235/TM 235 KF to achieve an efficient stirring without creating air bubbles Don’t
forget magnetic stirring bar!. Now switch on the device. The mains switch is situated on the left at the back side of
the TitroLine 7500 KF Trace. As soon it is turned on the TitroLine 7500 KF trace starts the conditioning process.
If the anolyte has freshly been filled in, the conditioning can take up to 10-20 minutes for generator electrodes
without frit and sometimes a few hours for generator electrodes with frit. The drift display is then > 1500 µg/min. If
the drift has fallen < 10 µg/min, the TitroLine 7500 KF trace is ready for first measurements.
