Thanks to the One Click™ interface, you can customize your methods. One unique home screen for each user with their own shortcut buttons offers One Click access to all routine tasks. It's easy to feel right at home from the start, which reduces learning time and helps increase data security.
Contact with Karl Fischer reagents should always be avoided. The Solvent Manager takes care of the filling, draining, and exchange of reagents. LevelSens additionally increases security by monitoring the solution and preventing waste bottle overflows.
METTLER TOLEDO takes into account the variability of samples and applications and offers options and methods to cope with any samples. METTLER TOLEDO's Karl Fischer titrators offer volumetric methods for water determination up to 100% and/or coulometric methods for low water content from 1 ppm to 5%. The titration vessel is made completely of glass which ensures exceptionally low drift, making the most accurate and precise results possible.
Gas phase extraction is the perfect solution for samples that are unable to be directly added into the titration vessel. Modern and extremely compact, the new InMotion™ KF Oven Autosampler allows up to 26 samples to be placed on a rack of only 25 cm. The temperature scan functionality speeds up the analysis of unknown samples by determining, in just one single run, the optimum temperature for heating the sample.
METTLER TOLEDO's titrators offer a broad range of possibilities to handle your data. Choose whether to export as CSV, PDF, or XML files. For full data security, LabX™ titration PC software supports the user in every action performed with the titrator. All results are stored in the LabX database.
Save time, reduce costs, and improve operational safety with seamless automation solutions. From simple sampling pumps to high throughput autosamplers. All parameters are determined simultaneously and shown on the instrument touchscreen. A computer is only required when handling a large product database or when data needs to be exported to LIMS or ERP. Read more

Utilize an extensive range of consumables that includes beakers, vials for Karl Fischer ovens, tubes, pH and conductivity buffers, electrolyte solutions, and much more. Read more
With the one click start of your Karl Fischer analysis, the pre titration is executed automatically by the method. During this step, the sample determination cannot be started and the keys on the terminal will appear grey. Once the pre titration is finished and no water is present in the cell anymore, the titrator switches to standby mode and the keys will appear white to signal that the sample can now be titrated.
The C20 and C30 are available with two different coulometer cells – with or without a diaphragm. For most applications, we recommend the cell without the diaphragm because it is almost maintenance-free. Due to its innovative design, this diaphragm-free cell from METTLER TOLEDO can even be used for the determination of water in oils.
The version of the cell with a diaphragm is recommended for applications such as the determination of moisture in substances containing ketones. It is also recommended if the best possible accuracy is required.
The most practical solution to this question is to add some blue silica gel to the top of the drying tube to serve as an indicator. As soon as the first trace of pink appears in this gel layer, it is time to change or regenerate the molecular sieve. Naturally, an increase in background drift can also indicate that it is time to replace the molecular sieve.
The first and most obvious answer to this question is that the solvent should be replaced as soon as the sample no longer dissolves. This, however, is only one of the reasons for changing the solvent. A second less obvious reason applies in the case of two component reagents where the titrant contains iodine, and the solvent contains all the other components necessary for the Karl Fischer reaction. One of these other components is sulfur dioxide and this can become depleted long before the dissolving capacity of the solvent is exceeded. As a general rule the solvent in these two component systems has an approximate water capacity of 7mg of water per mL of solvent. This means that in theory 40mL of solvent can accommodate 280mg of water before the solvent needs to be changed. As the typical titrant has a concentration of 5mg/mL, 280mg of water would require 56mL of titrant.
No, the InMotion™ KF oven can only be used with the Compact V30S as well as the T7 and T9 Excellence titrators
To reduce the drift value, make sure all the openings on the titrator have been greased (e.g. tube inserts, electrodes, adapters, etc.) and that you use dry and fresh molecular sieves and silica gel in your drying tubes. We recommend exchanging your molecular sieves every 6 weeks. If you still have high values, try to gently shake the titration vessel to collect traces of water from the glass walls.
The Compact C10/20/30SX Karl Fischer titrators do not possess a diaphragm. Without it, there’s no risk of getting it clogged and, hence receiving incorrect results. The C10/20/30SD Compact titrators possess a diaphragm, which can improve the drift value.
