Ease of use and safety for your analyses

The UDK 129 is an entry-level and reliable solution for safe distillations. The most suitable distiller for laboratories looking for a simple but efficient instrument for Kjeldahl nitrogen TKN, proteins, ammoniacal nitrogen, nitric nitrogen (Devarda), TVBN, sulfites, phenols, volatile acids, cyanides, and alcohol content.

The Kjeldahl distillation unit UDK 129 includes features that ensure efficient and reliable distillation, far beyond the expectations of an ordinary entry-level unit.

Programmable sodium hydroxide addition
High-precision pump ensuring constant accurate dosing of the reagent
Intuitive interface for easy analysis settings
Maximum safety for the operator
Unmatched flexibility with a wide accessory range

Unrivalled technologies to support your laboratory – Titanium Condenser and Technopolymer Splash Head

The UDK 129 features the unique VELP patented titanium condenser designed for efficient thermal exchange and low water consumption.

The distillate temperature is always kept below the Kjeldahl threshold value (35 °C), as indicated in the Kjeldahl method, without nitrogen loss.

Reduced water consumption
High resistance material with prolonged lifespan
Reduced break risks during routine cleaning

The exclusive VELP Technopolymer Splash Head incorporated in the UDK 129 is designed for high throughput providing state-of-the-art durability and resistance.

Chemical resistant materials
Unmatched lifespan of up to 10,000 analyses
Maintenance-free and no risk of breaking

Reliability and safety for your lab

The UDK 129 is provided with the most complete set of safety features to ensure maximum operator safety. Sensors monitor tube in place, safety doors and cooling water flow-rate.

The VELP Patented Steam Generator guarantees safe working conditions working without pressure:

Rapid pre-heating time
High performance and resistance
Maintenance-free
Works with deionized water

Intuitive user interface ensuring ease-of-use

The bright LCD display and easy-to-use menu guide the operator in setting the instrument working conditions, including distillation time and the volume of sodium hydroxide.

The low-profile button design ensures complete comfort and enables easy process handling.

Clear readability of analysis time
Intuitive menu and sub-menu navigation
Counters for maintenance
Dedicated service menu

TEMS™ Technology

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

Time Saving: rapid heating reduces wasted time
Energy Saving: limited energy consumption thus cutting CO_² emissions
Money Saving: cost reduction for each analysis
Space Saving: the narrow footprint saves valuable laboratory bench space

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 a 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.
