Semi-automatic Kjeldahl distillation unit 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 semi-automatic Kjeldahl distillation unit UDK 139 runs automatically, after setting distillation time, sodium hydroxide and water addition and steam generation output level between 10 and 100% using the innovative 3.5'' color touch screen. The high-precision pumps ensure constant accurate dosing of reagents.

The Kjeldahl distillation unit UDK 139 combines excellent value-for-money with high reliability and advanced performance.

Analysis times are reduced thanks to application optimization and the possibility to select up to 10 work programs.

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
  • Total safety: no internal pressure
  • Great repeatability
  • High performance and resistance
  • Maintenance-free
  • Safety-thermostat
  • Works with deionized water
  • Low thermal dispersion

     Patented Steam Generator


Improved communication leads to improved efficiency

The UDK 139 is a Kjeldahl automatic distiller equipped with a control panel with 3,5'' high resolution colour touch-screen graphic display and easy to use multitasking software that guides the operator step by step through menus and sub-menus. Easy to read and practical with all the most important parameters available at a single glance, the multitasking software enables the operator to set all the parameters for a fully automatic distillation and titration processes.
