UDK 149

Model : UDK 149

  • 230 V / 50-60 Hz
  • Included: A00001080 Provettone Ø 42x300 mm, 10001106 Collecting flask 250 ml, 10000247 Pincer for test tubes    **Inlet tube, discharge tube and protective film for touch screen are supplied with the instrument



Fully automatic Kjeldahl distillation unit, with external titrator connection, 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 automatic Kjeldahl distillation unit UDK 149 can be connected to several models of external potentiometric titrators for direct output of the final result and offering choice and versatility to the user.

It enables the final result to be obtained directly with a considerable saving of time. All the parameters of distillation and titration phases are stored in the method with the advantage of time-saving.

The high-precision pumps ensure constant accurate dosing of reagents. All the parameters concerning distillation and titration phases are easily programmable and stored in the archive onboard the instrument, to be then downloaded via pen-drive or directly to PC for maximum management flexibility.


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.

    Exclusive Titanium Condenser


The steam generator used by UDK Kjeldahl distillation units offers unique performance, being a patented solution

A thermostat ensures the correct functioning of the steam generator, a safety thermostat eliminates risks for the operator and guarantee safe working conditions.

The high level of precision and accuracy ensures correct and detailed results without any leaks even after intensive use.

  • Rapid (p)re-heating time
  • Low thermal dispersion
  • Great repeatability
  • High performance and resistance
  • Maintenance-free
  • Safety-thermostat
  • Works with deionized water
  • Total safety: no internal pressure

It is also possible to set the steam output from 10% to 100%.
