Automatic Kjeldahl Distillation Unit
The automatic Kjeldahl distillation unit UDK 149 operates automatically, after setting on the multi-function 3.5'' color touch screen water, boric acid and sodium hydroxide addition, distillation time and the steam generation output level between 10 and 100%.
Different automatic titrator models can be connected to the automatic distillation unit UDK 149 for direct output of the final result and offering choice and versatility to the user. The high-precision pumps ensure constant accurate dosing of reagents. All the parameters concerning distillation and titration phases are easily programmable.
Kjeldahl Distillation Units - TEMS™ Technology
Time Saving - Fast and frequent analyses; no heating delay between runs Energy Saving - Cooling water consumption starting from only 0.5 l/min; excellent insulation Money Saving - Cost reduction is substantial, in line with reduced power consumption Space Saving - The extremely compact footprint saves useful laboratory bench space
Kjeldahl Distillation Units - Exclusive Titanium Condenser
VELP Scientifica has developed and patented the innovative titanium condenser able to ensure high performance and considerable water savings (from 0.5 l/min). The graph shows the high efficiency of the titanium condenser compared to the traditional glass one available on the market. The titanium condenser ensures that distillate temperature always remains below the safe threshold value (35 °C), as indicated in the Kjeldahl method.
Kjeldahl Distillation Units - Maximum Flexibility
The automatic Kjeldahl distillation unit UDK 149 can be connected to several models of external potentiometric titrators. It enables the final result to be obtained directly, as it can easily be connected to different automatic titrator models. All the parameters of distillation and titration phases are stored in the method with the advantage of time saving.
