Thermal homogeneity and precision

Thermal homogeneity and precision
The DK 6 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 6 Series guarantees accuracy and repeatability. Program your methods with digestion time and up to 4 temperature ramps through the intuitive digital display. 

The DK 6 series perform batch digestion of up to 6 samples with 250 ml test tubes - Ø 42 m, reducing the power consumption of 13% compared to the previous series.

Low energy consumption permit to have low costs for every single analysis and limit CO2 release.

Space saving design

Space saving design
The new design of the DK Series has been studied in order to let laboratories to save valuable space under the fume hood. 

The DK 6 digestion units have very compact dimensions: the new aluminum heating block has been lowered as a consequence of the enhanced performance of the new Series.

The structure is manufactured from stainless steel studied and tested to assure a strong resistance to chemical or mechanical agents.

A new intuitive interface and protection

A new intuitive interface and protection
The new bright digital display provides maximum visibility and easy reading of the information. The inclination of the frontal panel protects it from the spillage and hot chemicals.

The usage of the instrument is controlled by only 4 keys: they allow an easy navigation through all the functions during programming or normale use.

The new grid ensures enhanced heating performances and protects the aluminum heating block and the tubes.

COD digestion with DK 6

COD digestion with DK 6
DK 6 is a versatile digester suitable for Kjeldahl N/Protein applications and Chemical Oxygen Demand in the environmental industry. 

In order to use the DK 6 for COD (Chemical Oxygen Demand) is necessary to configure it by adding a different support system able to manage all the glass required for the COD analysis for processing 6 samples simultaneously.

Trace Determination of Heavy Metals

Trace Determination of Heavy Metals
The DK 6 and TMD 6 are the reliable solution for digestion with aqua regia (nitrohydrochloric acid) in order to determine the acid-soluble proportion of metals in sewage sludges, sediments and soils In accordance with official methods (DIN 38414-S7 standard).
  • Water-jacketed condensers of TMD 6 retain all Hg, Cd, Pb, Cr, Cu, Zn, etc.
  • TMD 6 is composed of high quality glass components with supports for DK 6
  • Excellent accuracy and precision with a temperature homogeneity of ± 0,5 °C
  • Space saving design
  • Intuitive interface
  • TEMSTM Technology

Fume Neutralization System

Fume Neutralization System
For application where the digestion process produces fumes, acid gases or corrosive substances, the below specific accessories are strongly recommended:
  • JP Pump aspirates noxious fumes
  • SMS Scrubber neutralizes all the fumes

TEMS™ Technology

TEMS™ Technology
DK Series Kjeldahl digestion units work with the innovative TEMS™ benefits, for huge 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

Genuine consumables for your digestions

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.
