KF Titrando

The Karl Fischer Titrando for the modern titration laboratory

In addition to the Karl Fischer mode (KFT), this high-end titrator also includes the SET mode, which means that titrations can be carried out to a predefined endpoint.

"ITrode ready": The high-resolution, galvanically separated measuring interface - now also with additional digital measuring input for intelligent electrodes «iTrodes» - means that it is also possible to make high-precision pH measurements.

Thanks to its four MSB connections up to four 800 Dosino dosing systems can be connected to the 901 Titrando. These can be used for titration as well as for the automated addition of sample, standard and auxiliary solutions such as solubility promoters. All liquid handling commands are also available, which means that the aspiration of used reagent and the addition of fresh solvent can be automated.

Karl Fischer water determination is one of the most frequently applied laboratory methods. In contrast to other water determination methods, it is specific, fast and requires no expensive equipment. With an application range of 0.1% to 100% water volumetric Karl Fischer titration is used in a wide variety of fields. No matter whether you determine the water content in food, cosmetics or pharmaceutical products, the 901 Titrando is always the right instrument.
The sophisticated control algorithm of the Titrando has been adapted to the characteristics of the Karl Fischer reaction and guarantees highly precise results. You can choose between a polarized alternating current (I_pol) or a defined voltage (U_pol) to be applied to the electrode. Both working modes yield fast and precise results.
Different reagents require different parameters. The 901 Titrando allows you to select the appropriate method for each type of reagent.
Combined with the easy and intuitive user guidance this is the optimal instrument for routine operation as well as for demanding applications in research labs. With the 901 Titrando you acquire a titration system that meets all imaginable requirements and demands no compromises.
Just one example: the KF icons show you at a glance whether the instrument is still busy conditioning or whether you can start the water determination.
The electrode test and the newly created parameter «safety stop» prevent cell run-over during conditioning. If, for example, the electrode is not connected correctly or the titration cell is very humid, conditioning is stopped after a given time or a given volume of KF reagent added. This new feature increases work safety in your laboratory.

Optional:

• Use the 803 KF Titration Stand for stirring and manually exchanging the spent titration vessel contents. With the integrated membrane pump, solvent can be aspirated or added without the cell having to be opened. This means vastly reduced conditioning times.
• Automatic reagent exchange
  The exchange of the spent KF Reagent in the titration cell can be performed manually with the 803 KF Titration Stand. The automatic procedure is even more convenient: You fix the time and the instrument carries out the automatic reagent exchange with the Dosino. In both cases, contact with hazardous reagents is avoided.
• The Dosino - the optimal KF dosing system
  Thanks to the «Empty» command the Dosino can be emptied completely; this avoids cumbersome opening and cleaning of the Dosing Unit.Once the reagent is used up, the remaining contents of the cylinder can be transferred directly to the bottle or the titration cell. The empty reagent bottle is then replaced, the Titrando executes the «Prep routine and the titer determination of the new reagent can be started. In contrast to the Exchange Unit, multiple rinsing before titer determination is not necessary; this saves both time and reagents.When not being used, KF reagents tend to produce precipitates within the stopcock and tubes, requiring time-consuming cleaning operations. The «Empty» command does away with this problem.
