Automatic Kjeldahl Digester

The VELP DKL 20 (20-position with 250/400 ml tubes, Ø 42 mm) Kjeldahl Digestion Unit for nitrogen analysis and protein determination - All regular functions are fully automated, including lowering the test tubes into the heating block, lifting the tubes to expedite cooling and separating the suction manifold from the tube rack, enabling the rack to be slid out and replaced by another to start the next run.

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!

Special Application: DKL 20 can be used also for testing Chemical Oxygen Demand Its lift automatically manages all the glass required for processing 20 samples simultaneously
