Instrument Introduction:


The 851 exquisite first generation Coulombic Karl Fischer titration instrument integrates multiple advanced technologies from Switzerland's Vantone, and is a representative work of high-end Coulombic Karl Fischer titration instruments. Based on patented non dead volume burettes and multiple intelligent technologies, it is the best choice for highly automated and intelligent laboratories.


MetrohmMetrohm 851Exquisite first generation Coulomb Karl Fischer titration instrument for water content（851 Titrando）Main features:


1. No need to press the button to automatically start titration
During the experiment, it is possible to forget to press the start button and add the sample to the titration cup. In this case, the titration system will use the moisture in the sample as the background to react in a pre equilibrium manner, making it impossible to calculate the concentration. This results in ineffective injection and requires retesting. 851 does not require any buttons, adding the sample and titration will start automatically immediately. Don't worry about misoperation, prevent wasting reagents and samples, and save valuable experimental time.

2. Automatic replacement of reagents
By using only one of the four MSB interfaces, 851 can connect to the DosiTM dosing unit, allowing for automatic replacement of reagents without the need to open the titration cup. This prevents moisture from the air from entering the titration cup, shortens the equilibration time after reagent replacement, and avoids direct contact with toxic reagents. The reagent replacement program can be automatically initiated based on indicators such as the number of times the reagent is used, the expiration date, the moisture capacity, or the drift value. The multi thinking unit can also be used to add samples, standard solutions, or auxiliary solvents such as co solvents.

3. Optional large screen touch screen control or Tiamo computer workstation control

4. Measurable Bromine Index
The bromine index is a measure of the number of double bonds present in a sample, and no additional accessories are required for measurement. The original indicator electrode, generating electrode, and titration cup are also suitable for this application. Just replace the reaction medium.

5. Rich configuration
By combining the 814 and 815 USB robot sample processors with the 874 Kjeldahl heating furnace, we can provide you with a highly automated titration system.
