Automated volumetric KF titration including sample preparation
MATi-11
- Przegląd funkcji
Fully automated system for volumetric Karl Fischer water content determination in up to 53 samples. This system is controlled with OMNIS software and consists of an 815 Robotic USB Sample Processor XL, a 901 Titrando, a Polytron PT 1300 D and extensive accessories.
The samples are weighed out into beakers, sealed to protect against humidity and placed on the rack. Before the actual titration, a defined volume of KF reagent is added and the sample is pulverized with the help of a Polytron. The water that is released is titrated afterwards. Even samples of poor solubility, e.g., tablets, can be analyzed without difficulty with this method. The use of solubility promoters can be avoided in this way.

901 Titrando
2.901.0010
The Karl Fischer Titrando for the modern titration laboratoryIn addition to the Karl Fischer mode (KFT), the high-end titrator is also equipped with the SET mode and can thus perform titrations to a predefined endpoint."iTrode ready": As a result of the high-resolution, galvanic measuring interface – now also for the first time with additional digital measuring input for the intelligent "iTrodes" electrodes – it is additionally possible to perform pH measurements with a maximum of precision.Thanks to the four MSB connectors, up to four Dosinos can be connected to the 901 Titrando. These can be used not only for titration, but also for the automated addition of sample, standard and auxiliary solutions such as solubility promoters. Furthermore, you have all of the Liquid Handling commands at your disposal, which means that the aspiration of exhausted reagent and the addition of fresh solvent can also be automated.For use with OMNIS Software, tiamo software, or Touch Control unit. Compliance with GMP/GLP and FDA regulations such as 21 CFR Part 11, if required
Polytron PT 1300 D
2.136.0100
Polytron PT 1300 D - Metrohm versionHomogenizer that can be controlled directly by OMNIS Software, tiamo™ or Touch Control.The Polytron PT 1300 D is comprised of a control unit and a drive. The coupling system on the drive permits simple and rapid replacement of the aggregates without additional tools.Solid samples can be pulverized without difficulty. However the instrument is also highly suitable for ensuring thorough mixing in viscous samples.
772 Pump Unit – aspirate
2.772.0120
Peristaltic pump for direct connection to Sample Processors. The "Aspiration" version contains extensive accessories for the aspiration of titered-out solutions.
786 Swing Head
2.786.0040
Additional equipment for Robotic Sample Processors XL without titration or transfer heads.
