VELP digestion/mineralization systems are developed for different applications, from the determination of nitrogen and protein according to the Kjeldahl method (TKN) in food analysis to environmental analyses (Chemical Oxygen Demand) and chemical-pharmaceutical applications.

The DKL Series is revolutionary in terms of savings, thanks to TEMS technology:

Time Saving - Only 22 minutes to reach 420 °C / 788 °F: the DKL gets to work immediately.
Energy Saving - 35% reduction in power consumption, cutting CO2 emission.
Money Saving - Huge cost reduction for each analysis.
Space Saving - The narrow footprint saves valuable laboratory bench space.
    The aluminum block requires no maintenance and ensures a complete and homogeneous digestion, with high reliability. The automatic placing of samples into the heating block and the subsequent lifting for cooling allow all operations to be conducted safely without manual activity.
    The DKL Series has an innovative and graphic display that guides the user in a simple and fast way, planning and monitoring the various digestion phases.
    VELP knows that you are more comfortable operating in a language that relates to you and enables you to upgrade, adding multiple languages to those pre-installed.
    The DKL Series includes a wide range of models for a simultaneous digestion of 8, 12, 20 or 42 samples: DKL8 (8 x 250 ml), DKL12 (12 x 250 or 400 ml), DKL20 (20 x 250 ml),DKL42/26 (42 x 100 ml).

DKL digestion systems are supplied with a complete set of accessories, including:
- Lift
- Stand for Sample Rack
- Sample Rack
- Suction Cap
- Lift Drip Tray
- Test Tubes

    In order to neutralize the fumes produced during the digestion, VELP suggests combining the DKL system with the JP Recirculating Water Pump and the SMS Scrubber.
