DKL Series and DK Series - Kjeldahl Digesters
DK Series digesters are traditional digesters, consisting of an aluminum heating block to offer high thermal homogeneity. The DKL Series of digesters offers a premium level of automation: lowering and lifting of the samples take place automatically, as well as the separation between the test tubes and the suction cup. VELP digesters work in accordance with a variety of Standards (such as AOAC, ISO, EPA, DIN etc.)

DKL Series - Fully Automatic Digestion Units
Fast, safe and compact aluminum heating block digesters for unattended operations in laboratories performing Kjeldahl analysis for diversified applications in food & feed, beverage (nitrogen, protein, Total Kjeldahl Nitrogen), environmental (COD, Total Kjeldahl Nitrogen, Heavy Metal Trace), chemical and pharmaceutical (organic nitrogen) industries.
- The auto-lift facilitates the operator by reducing strain and time spent in manual tasks. The customizable programs allow for repeatable processes to run fully unattended.
- Extremely fast aluminum heating block is capable of reaching 420°C in just 20 min and maintaining temperature with an accuracy of ± 0.5°C. A complete set of available accessories allows for analysis of all sample types and quantities.
The separated control panel is protected from heat and spills ensuring reliability and longevity. The innovative microprocessor controls the temperature of the block and is supported by safety thermostat.
- The DKL Series is constructed with highly resistant materials such as the corrosion-protected housing that provides resistance to harsh working environments.
- The intuitive control panel makes operating and monitoring every stage of the analysis effortless. Many standard methods are pre-loaded and more can be customized and saved.
- Thanks to the narrow footprint, the DKL Series saves valuable fume hood space to accommodate other instruments.
Available configurations:
- DKL 8 (8 positions for 250 ml test tubes, Ø 42 mm)
- DKL 12 (12 positions for both 250 and 400 ml test tubes, Ø 42 mm)
- DKL 20 (20 positions for both 250 and 400 ml test tubes, Ø 42 mm)
- DKL 42/26 (42 positions for 100 ml test tubes, Ø 26 mm)
DK Series - Semi-Automatic Digestion Units
- The aluminum heating block ensures high thermal homogeneity heating up to 450°C.
- The DK Series digesters guarantee fast temperature set point reaching, reducing the energy consumptions.
- Save valuable space under the fume hood with the VELP DK digesters. The design of the DK Series ensures minimum space requirement.
- The bright digital display provides maximum visibility and easy reading of the information. It supports the recording of up to 20 methods with 4 temperature ramps.
- All models DK models are available with tubes and all necessary parts to operate. A wide range of accessories and genuine consumables is available to match analytical requirements.
Available configurations:
- DK 6 (6 positions for 250 ml test tubes, Ø 42 mm)
- DK 6/48 (6 positions for 300ml test tubes, Ø 48 mm)
- DK 8 (8 positions for 250 ml test tubes, Ø 42 mm)
- DK 20 (20 positions for 250 ml test tubes, Ø 42 mm)
- DK 18/26 (18 positions for 100 ml test tubes, Ø 26 mm)
- DK 42/26 (42 positions for 100 ml test tubes, Ø 26 mm)
For application where the digestion process produces fumes, acid gases or corrosive substances, VELP manufactures the following accessories:
- JP Pump aspirates noxious fumes
- SMS Scrubber neutralizes all the fumes
