DK 8 Digestion Unit
Kjeldahl Digestion Units with 8-position aluminum heating block that offers an excellent thermal homogeneity.
Thermal homogeneity and precision
The DK 8 Series digestion unit with aluminum heating block ensures high thermal homogeneity heating up to 450 °C. The temperature of the block is constantly controlled by a microprocessor and is extremely stable, homogeneous and precise: ±0.5°C at all selectable temperatures.
The DK 8 Series guarantees accuracy and repeatability. The DK 8 performs batch digestion of up to 8 samples with 250 ml test tubes – Ø 42 m, reducing the energy consumption (-13% compared to the previous series). Low energy consumption provides lower costs of analysis and limits CO2 release.
Space saving design
The design of the DK series has been carefully engineered to allow laboratories to save valuable space under the hood.
DK Digesters have very compact dimensions: the new aluminum heating block has been lowered and the vertical proportions allow to free precious space in the laboratory.
The structure is made of stainless steel that has been specifically designed and tested to ensure strong resistance to chemicals and mechanical stress.
The aluminum block protection grid provides enhanced heating performance and protects the heating block from splashes and chemicals.
Easy-to-use with the intuitive digital interface
The bright digital display provides maximum visibility and easy-to-read information.
The instrument is operated with 4 keys to navigate the menu options and program the digestions in a simple and fast way.
Through the intuitive graphic display it is possible to set up to 20 methods with 4 temperature ramps.
Acoustic signals inform the operator of the completion of the analysis facilitating the daily use of the digester.
The inclination of the front panel protects it from chemical spillage at high temperatures.
Fume Neutralization System
- JP Pump aspirates noxious fumes
- SMS Scrubber neutralizes all the fumes
TEMS™ Technology
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

Genuine consumables for your digestions
Choosing the right consumables allow the optimization of analytical operations to achieve the highest possible performance of your Digestion Unit. We strongly recommend the use of VELP original consumables in order to be sure to obtain the best performance form your VELP instrument.
The addition of a suitable catalyst, along with high temperature, have influence on the speed and the efficiency of the mineralization in Kjeldahl analysis. Achieving the highest level of performance in a wide range of Kjeldahl applications is now possible with VELP Scientifica genuine KjTabs™ catalyst and antifoaming tablets.
VELP Scientifica Nitrogen Free Weighing Boats are the perfect solution to all the difficult transfer operations of powders or syrupy samples into mineralization test tubes.
