Thermal homogeneity and precision

Thermal homogeneity and precision

The DK 6 Series digestion unit with aluminium 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. 

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 the following test tubes dimensions: 
  • DK 6   250 ml tubes - Ø 42 mm
  • DK 6/48   300 ml tubes - Ø 48 mm

Compact design and maintenance free

Compact design and maintenance free

DK 6 digestion units have very compact dimensions aimed to reduce the footprint and save space in your lab. The design of the heating block of VELP digestion unit has been studied in order to reduce space under the fume hood. 


The DK Series aluminum heating block does not require maintenance. It needs to be combined with a support system, sample rack (with heat shields), suction cap and test tubes (required accessories).
 

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.

Fume Neutralization System

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.
