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.
The titanium condenser ensures that distillate temperature always remains below the safe threshold value (35 °C),as indicated in the Kjeldahl method, without nitrogen loss.
- Rapid (p)re-heating time
- Total safety: no internal pressure
- Low thermal dispersion
- Great repeatability
- High performance and resistance
- Works with deionized water
- Excellent usability
- Flexible, versatile and multi-language
- Intuitive data entry and programming
- Unlimited library with all the analyses
- Data export in .xls, .txt, .csv (according to LIMS) also on USB key
- Direct access to the archive from remote PC in real time without any download
The automatic Kjeldahl analyzer UDK 159 is the top of the range model offering the ultimate in capabilities including colorimetric titration, as recommended by the AOAC.
The UDK 169 colorimetric titration is based on precise chemical reactions with indicators. VELP integrated titrator works by dosing an acidic titrant solution to the boric acid containing the ammonia distilled from the sample. This titration process results in a color change that is evaluated by the system.
- not sensitive to volume and external light
- automated, for maximum simplicity and security
