UDK 159 Automatic Kjeldahl Analyzer
Fully automatic Kjeldahl Analyzer (distillation unit with integrated colorimetric titrator), 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.
UDK 159 combines distillation with analysis.
