Description

 

Thermal homogeneity and precision

The DK 20 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 20 guarantees accuracy and repeatability. Program your methods with digestion time and up to 4 temperature ramps through the intuitive digital display.

The DK 20 perform batch digestion of up to 20 samples with the following test tubes dimensions:

  • DK 20 250 ml tubes – Ø 42 mm

Compact design and maintenance free

DK 20 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).

 

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

DK 20 Kjeldahl digestion units work with the innovative TEMS™ benefits, for huge savings.

Time Saving: from Ambient to 420 °C in only 35 minutes
Energy Saving: limited energy consumption
Money Saving: cost reduction for each analysis
Space Saving: reduce unnecessary use of 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 genuine KjTabs™ catalyst and antifoaming tablets.

VELP Nitrogen Free Weighing Boats are the perfect solution to all the difficult transfer operations of powders or syrupy samples into mineralization test tubes.
