Preparação de amostras para o KF Ti-Touch: Sistemas

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.

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.

The 885 Compact Oven Sample Changer is used for thermal sample preparation in Karl Fischer titration. In the oven the samples can be heated up to 250°C. The moisture contained in the sample evaporates and is transported by a dry carrier gas into the titration cell, where the analysis takes place.
