Automatic Kjeldahl Nitrogen Protein Analyzer
Fully automatic Kjeldahl distillation unit, with external titrator connection, for your analyses concerning different applications such as determining ammoniacal nitrogen, protein determination, nitrogen content (Kjeldahl or direct alkaline distillation), nitric nitrogen (after reduction/Devarda), phenols, volatile acids, cyanides and alcohol content.
The automatic Kjeldahl distillation unit UDK can be connected to several models of external potentiometric titrators for direct output of the final result and offering choice and versatility to the user.
It enables the final result to be obtained directly with a considerable saving of time. All the parameters of distillation and titration phases are stored in the method with the advantage of time saving.
The high-precision pumps ensure constant accurate dosing of reagents. All the parameters concerning distillation and titration phases are easily programmable and stored in the archive on board the instrument, to be then downloaded via pen-drive or directly to PC for maximum management flexibility.
