Fully automatic Kjeldahl distillation unit, with external titrator connection
Vreceiver™ boric acid with indicator sealed bags
Fully automatic Kjeldahl Analyzer (Distillation unit + integrated colorimetric titrator) with connection to autosampler, for high sample throughput, maximum flexibility and unattended operation.
The completely automatic Kjeldahl distillation and titration system offer great performance and the maximum in terms of safety for the user.
Automatic addition of all the reagents involved with low level warning, simplifies the routine activity whilst the possibility to set the steam output from 10% to 100% enlarges the application range of UDK 169. Automatically the unit will perform distillation and titration.
The possibility to set the steam output from 10% to 100% makes the instrument highly recommended for a wide range of applications, including the most specific, which require special parameters. UDK 169 is ideal for reliable determination of ammoniacal nitrogen, protein nitrogen (Kjeldahl), nitric nitrogen (after reduction/devarda), phenols, volatile acids, cyanides and alcohol content.
At the end of the analysis, all the residues can be aspirated automatically, both for distillation and titration.
UDK 169 can be used either alone or in combination with the AutoKjel autosampler, for a highly productive system capable of autonomously processing up to 24 samples with standard test tubes (250 ml) or 21 Jumbo test tubes (400 ml).
Sample tubes are taken from the carousel and fed directly into UDK 169 for further processing and reliable results, allowing the user to operate in complete safety and with extreme ease, without requiring an attendant.
The UDK 169 & AutoKjel Kjeldahl analyzer is developed for continuous operation, providing the maximum sample throughput and data processing automation.
VELP Scientifica has developed and patented the innovative titanium condenser able to ensure high performance and considerable water savings (from 0.5 l/min at 15 °C – 1 l/min at 30 °C) with minimal maintenance.
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.
The automatic Kjeldahl analyzer UDK 169 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.
