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.
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
