  • The DK 20 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 20 Series guarantees accuracy and repeatability. The DK 20 series perform batch digestion of up to 20 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.
  • 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.
  • 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.
  • DK 20 is a versatile digester suitable for Kjeldahl N/Protein applications and Chemical Oxygen Demand in the environmental industry.
    • In order to use the DK 20 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 20 samples simultaneously.
  • 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
