UDK 129 Kjeldahl Distillation Unit

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 CO2 emissions
  • Money Saving: cost reduction for each analysis
  • Space Saving: the narrow footprint saves valuable laboratory bench space
