Walk-away digestion unit to maximize productivity

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

The DKL series provides the operator with the ultimate technology that allows the laboratory technician to set up the analysis 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 make 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!

Premium performance with aluminum heating block

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.

Compact design to save space in your lab

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 need: fit more instruments on the same lab bench or make different use of the extra space available.

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

Intuitive operations

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.

COD digestion with DKL 20

DKL 20 is a versatile digester suitable for Kjeldahl N/Protein applications and Chemical Oxygen Demand in the environmental industry.

In order to use the DKL 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.

Fume Neutralization System

For applications where the digestion process produces fumes, acid gases or corrosive substances, the below specific accessories are strongly recommended:

KS 1000 Scrubber neutralizes all the fumes

TEMS™ Technology

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

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.
