UDK 159 Automatic Kjeldahl Analyzer
VELP Scientifica | Distillation Units
Fully automatic Kjeldahl Analyzer (distillation unit with integrated colorimetric titrator), for determination of 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.
Automated Operation
- Programmable boric acid, water, sodium hydroxide addition
- Not necessary to set distillation time when titrating
- Incorporates an AOAC recommended colorimetric titrator
- Selectable steam generation output level 10% – 100%
- Auto removal of residues from titrator & sample tube
