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

UDK Kjeldahl distillation units work with the innovative TEMS™ benefits, for huge savings.

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.

Vreceiver™ boric acid with indicator sealed bags

VELP unique Vreceiver™ is a certified formula composed of Boric Acid powder and a mixture of indicators mentioned by AOAC methods (Bromocresol green and Methyl red) allowing fast and standardized receiving solution preparation for colorimetric titration.

The receiving solution is prepared in few minutes facilitating the day by day operations instead of the typical time consuming process using single reagents. The result is a reliable and standardized solution for colorimetric titration. The Vreceiver^TM is suitable for all distillation units especially with VELP automatic UDK series (159 and 169) with integrated colorimetric titrator.
