Kjeldahl Digestion Units - Unparalleled Productivity

  • The DKL Series Automated Kjeldahl Digestion Units provide users with the ultimate technology whose objective is to simplify operation, ensuring significant savings. Once set up, the operator can just press the START button and walk away.
  • All regular functions are fully automated, including lowering the test tubes into the heating block, lifting the tubes to expedite cooling and separating the suction manifold from the tube rack, enabling the rack to be slid out and replaced by another to start the next run.
  • Ease of loading and unloading make the VELP DKL a pleasure to use when carrying out Kjeldahl analysis, and there is no need to handle the sample when the tubes are hot!
  • Kjeldahl Digestion Units - Aluminum Block for Premium Performance
  • DKL Series heating block is entirely made in aluminum alloy, the best material when temperature precision, stability and homogeneity are required.
  • Even in terms of repeatability and conductivity, aluminum offers incredibly high performance!
  • In accordance with GLP, the analyst must be able to determine at what temperature digestion occurred: just by using a common temperature probe, the analyst can measure the effective temperature.
  • And do not forget DKL capabilities in reducing the heating time…

Kjeldahl Digestion Units - TEMS™ Technology

Time Saving: from Ambient to 420 °C in only 22 minutes Energy Saving: up to - 35% of consumption Money Saving: huge cost reduction for each analysis Space Saving: reduce unnecessary use of space

Kjeldahl Digestion Units - High Heating Speed on DKL

The graph shows that rapid heating of DKL Kjeldahl digestion units: by increasing the heating speed, the analysis time is reduced!

All the advantages of a rapid heating combined with the known benefits of a block digester: excellent reliability, high precision and homogeneity of the temperature, with the possibility to know the real temperature of the digestion.

Kjeldahl Digestion Units - Low Energy Consumption on DKL

Look at the significant amount of energy that you can save with a DKL Kjeldahl digestion units compared to a conventional digester. DKL Series reduces dramatically consumption and CO2 emission. In a world where respect for the environment is increasingly important, VELP shows exceptional qualities, providing a significant contribution to this topic cutting any form of pollution. Perform more analyses or use other instruments to increase your business…without any additional cost!
