Versatile, safe and precise block digesters for Kjeldahl analysis

Kjeldahl Digestion Units with 6-position aluminum heating block that offers an excellent thermal homogeneity.


  • The DK 6 digesters are made up of an aluminum heating block which guarantees high thermal homogeneity, for a maximum temperature of 450°C.
  • The temperature of the block is permanently controlled by a microprocessor with an accuracy of ± 0.5°C, which makes it particularly suitable for digestions for Kjeldahl, COD applications and the determination of heavy metals in trace amounts.
  • The DK series provides excellent test accuracy and repeatability. The DK 6 allows you to analyze up to 6 samples at a time and accepts test tubes of 250 ml – Ø 42 mm. VELP semi-automatic digesters guarantee low energy consumption (13% less than the previous series) and significantly reduce analysis costs
