Karl Fischer Titration KF-750 | Determination of the water content: Karl Fischer Titration has its place in every laboratory. Karl Fischer Titration KF-750 The KF-750 is a coulometric titrator. The water content and the water content determination according to Karl Fischer Titration impresses with its very good accuracy. With this KF titrator, nothing can actually go wrong when determining the water content according to Karl Fischer. The display, which is large and easy to read, shows every step in the process in a dialog. The pre-parameterized methods thus additionally facilitate the work. In addition, the versatility of the two KF titrators makes the instruments efficient and easy to operate. The KF measuring station is suitable for almost all areas such as the pharmaceutical, chemical, food or petroleum industries.

The coulometric KF titrator is the ideal instrument for determining even the lowest water content in samples. In the coulometry of a titration solution, the determination of the concentration titer is not necessary, making it easier to operate than in volumetric titration. Many experienced analysts still feel the smell of pyridine in their nose with horror when they hear the name Karl Fischer. However, modern reagents and easy-to-operate analytical instruments cleaned up thoroughly with such ideas. Today, coulometric and volumetric Karl Fischer titrators allow practically all applications to be performed simply, quickly and accurately. Because of its selectivity and accuracy, Karl Fischer titration has become the most important method for water and moisture determination. With the KF-750, titration can also be followed “live” in the form of a measurement curve. At the touch of a button, it is possible to switch between classic and graphical display.

Karl Fischer Titration KF-700 | Determination of water content – The Karl Fischer Titration method for analytical water determination is considered the most important method for determining water content. Volumetric titration is the “classical” Karl Fischer titration.

The fundamental difference between volumetric and coulometric titration is the method used. One advantage of the volumetric method over the coulometric method is the lower effort required. The Karl Fischer volumetric titrator is more flexible when using solvents. The measuring range goes from 0.01 percent to 100 percent. For water content and water determination, the Karl Fischer method is used in the laboratory.. For all its advantages, manual titration is still established as the standard application in the laboratory. A piston burette with exchangeable dosing attachment is the first choice when perfection and flexibility are required. With regard to the aging process of transformer oil, the Karl Fischer Titration KF-700 is used. A special form of dosing is the “Preparing solutions” mode.

In this mode, a solvent is dosed up to the desired target concentration. A sample is weighed in, the volume added is calculated using a calculation formula and then added. This mode is suitable, for example, for the preparation of standards and solutions for viscometry. Important features: Automatic calculation of the addition volume without additional PC software. Dosing and filling speed can be optimally adapted to the dosing solution. Several methods with different parameters can be stored. Automatic transfer of the weight of a connected balance.

Usually, 10-15 user methods are sufficient for most needs.

Karl Fischer Titration KF-7751 | Determination of Water Content – The Karl Fischer Titrator KF-7751 is a generalist when it comes to potentiometric and volumetric titration. As an universal titrator, the KF-7751 offers more application possibilities than the KF-700. In practice, there are differences between coulometric and potentiometric or volumetric titration. After switching on the instrument, the Karl Fischer Titrator starts working immediately, with the default settings starting in the background. The KF titrator has several interfaces for data communication. It is possible to operate an analytical balance via the interface to the KF titrator. To connect a printer, use the USB ports of the device. Karl Fischer titration has also become established for transformer oils for determining the water content in the oil or the water content. The Karl Fischer Titrator can be cleaned with a soft cloth and water using normal household detergent.

General properties: Brilliant TFT display, which can be read even from the side. Exchangeable caps with storage of all relevant cap and reagent data in the cap. Unlimited communication via up to two USB-A, one USB-B, one LAN and two RS232 interfaces. Storage of results as PDF and CSV on USB stick or network.

Preinstalled standard methods. Special features of the KF-7751: Wireless electrode recognition for ID electrodes for highest security during measurement and calibration. High-resolution inputs for pH/mV electrodes and temperature measurements for pH, ISE, redox titrations. Ideal for non-aqueous titrations such as acid and base number in oils. Measuring input for polarizable electrodes. Linear and dynamic titration to inflection points (equivalence points) and titrations to end point. pH Stat titrations. Volumetric KF titration.
