UDK 169 with AutoKjel Autosampler - Automatic Kjeldahl Nitrogen Protein Analyzer

Reference: VEL-S30200165

The UDK 169 is designed for high-throughput laboratories looking for precise and reproducible results of Kjeldahl nitrogen TKN, proteins, ammoniacal nitrogen, nitric nitrogen (Devarda), TVBN, sulfites, phenols, volatile acids, cyanides, and alcohol content.

UDK 169 can be used in combination with the AutoKjel autosampler, for a highly productive system capable of autonomously processing sample tubes, which are fed directly into the fully automatic distillation and titration unit.

The fully automatic process ensures efficient operations, distillation and titration performed simultaneously
Shortest time-to-results with online titration and automatic results calculation
Premium result accuracy and precision thanks to the integrated colorimetric titrator with high precision burette
Programmable boric acid, water, sodium hydroxide addition
Selectable steam generation output level 10% – 100%
Auto removal of residues from titrator & sample tube
Clear and intuitive operations thanks to the Smart User Interface and digital display
Maximum safety for the operator
Unmatched flexibility with the autosampler and a wide accessory range
