UDK 169 with AutoKjel Autosampler
VELP Scientifica | Distillation Units
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 theAutoKjel 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 Interfaceand digital display
- Maximum safety for the operator
- Unmatched flexibility with the autosampler and a wide accessory range
