VELP DKL 20 Automatic Digestion Unit

VELP DKL 20 Automatic Digestion Unit

Walk-away digestion unit to maximize productivity

DKL digesters are fully automatic and immediately ready to use, consisting of an aluminum heating block, automatic sample lift, suction hood, test tubes, tube rack, and drip tray.

Operators can select from a library of 54 programs (30 pre-installed + 24 customizable), press START, and walk away, maximizing lab productivity.
Ease of loading and unloading makes the VELP DKL ideal for Kjeldahl analysis, eliminating the need to handle hot samples.

Premium performance with aluminum heating block

DKL’s aluminum heating block reaches 420°C in just 20 minutes with excellent temperature stability.
The microprocessor ensures precise temperature control with ±0.5°C accuracy.
Aluminum provides superior repeatability and conductivity, drastically reducing digestion time according to the Kjeldahl method.

Compact design to save space in your lab

The DKL series is designed with a compact footprint to optimize bench space.
Ideal for use under fume hoods, it minimizes space usage while maintaining full functionality.

Intuitive operations

Enjoy the simplicity of the DKL’s bright, easy-to-read display.
View current temperature and ramp settings at a glance.
Save up to 54 programs (30 pre-installed, 24 customizable) with up to 4 temperature ramps.
Selectable language options (including ideograms) enhance usability and efficiency.

COD digestion with DKL 20

DKL 20 supports Kjeldahl N/Protein applications and Chemical Oxygen Demand (COD) analysis in environmental testing.
For COD use, configure with a dedicated support system to manage all required glassware for 20 simultaneous samples.

Fume Neutralization System

For digestion processes producing fumes or corrosive gases, use the KS 1000 Scrubber to neutralize all fumes effectively.
