Automatic Kjeldahl Analyzers


Automatic Kjeldahl Analyzers 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 distillation unit is used to perform nitrogen analysis and protein determination according to Kjeldahl method in food&feed industry and other applications in environmental and chemical industries after having digested the sample accurately. Our new range of UDK Series Kjeldahl distillation units includes a choice of automation features and is designed to meet the most diversified laboratory needs.
This is our fourth generation of steam distillation units, showing a continuous improvement and developing of our instruments. Unparalleled technology along with premium materials for high-quality products and extremely reliable results in terms of the quantification of nitrogen content and protein determination in different samples. It is also the third series of instruments to carry the TEMS™ technology logo, reflecting the significant investment in design to achieve major advantages concerning environmental protection and economy.
