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

Main technical parameters

·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 proceed
The concentration calculation resulted in the invalidity of this 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.

·Automatic replacement of reagents
By using only one of the four MSB interfaces, 851 can be connected to the DosiTM dosing unit, allowing for automatic replacement of reagents without the need to open the titration cup, preventing moisture from entering the cup
The post dose equilibrium time is shorter and direct contact with toxic reagents is avoided. 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
It can also be used to add samples, standard solutions, or auxiliary solvents such as co solvents.

·Optional large screen touch screen control or Tiamo computer workstation control

·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.

·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
