• 230V / 50-60Hz
• 12 heating places
• Fully automatic and immediately ready to use
• Library of 54 programs (30 pre-installed + 24 customizable)
• Aluminum heating block can reach up to 420C (842 F) in just 20 min

Automatic Kjeldahl Digestion Units with 12 positions aluminum heating block that offers excellent thermal stability and homogeneity. 

DKL digesters are fully automatic and immediately ready to use, as they consist of an aluminum heating block, a lift for automatic sample handling, a suction hood, test tubes, a test tube rack, and a drip tray.

The DKL series provides the operator with the ultimate technology that allows the laboratory technician to set up the analysis by choosing from a library of 54 programs (30 pre-installed + 24 customizable), press START, and walk away, boosting the lab productivity.

Ease of loading and unloading makes the VELP DKL a pleasure to use when carrying out Kjeldahl analysis, and there is no need to handle the sample when the tubes are hot!

DKL extremely fast aluminum heating block is capable of reaching 420°C in just 20 min with best-in-class temperature stability.

The choice of premium materials and the powerful microprocessor guarantee precise block temperature with an accuracy of ± 0.5°C.

Even in terms of repeatability and conductivity, aluminum offers incredibly high performance!

DKL digesters drastically reduce the time needed to reach the digestion temperature according to the Kjeldahl method. 

Everybody knows that there is never enough bench space in a laboratory. This is why we have made the DKL series as compact as possible.

The narrow footprint enables you to optimize bench space according to to need: fit more instruments on the same lab bench or make different use of the extra space available.

Many labs prefer to perform mineralization under a fume hood, and the compact design of the DKL ensures minimum use of precious space. 

Enjoy the simplicity of the DKL’s display. Extremely bright, easy to read, and practical with all the fundamental parameters available at a single glance.

Current temperature and ramp settings are clearly viewed on the display.  Save up to 54 programs (30 pre-installed, 24 customizable) with up to 4 temperature ramps. 

Monitor each stage of analysis as well as select options such as language (including ideograms).

Improved communication leads to improved efficiency.

The DKL series uses the unique TEMS technology, which provides significant savings.

Time: fast heating to 420 °C in just 22 minutes, excellent reliability, homogeneity, and temperature accuracy.

Energy: reduced consumption by 35%, reduced CO2 emissions by reducing pollution.

Money: significant cost reduction for each analysis, increases the number of analyses without additional costs.

Space: the compact profile, minimum use on the bench for optimal laboratory management

For applications 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
