The fully auto DKL 20 Digestion Unit works on 20 (x 250 ml, external diameter 42 mm) test tubes simultaneously. The System is composed of an Aluminum Heating Block offering excellent temperature homogeneity, precision and accuracy; an Auto Lift and an Auto Suction Cap and is supplied as a complete package including test tubes, Sample Rack and Drip Tray. The DKL 20 incorporates VELP’s revolutionary TEMS™ technology for unprecedented Savings in terms of Time, Energy - as much as 35%, Money and Space. High-Tech but Simple to use,  a Microprocessor controls the block temperature whilst an electronic Auto-Calibration System ensures excellent reliability and repeatability of analysis. A Practical Interface with LCD Graphic Display allows access to all the data including the Multi-Language Library and the 54 Programs available, 24 of which are user-programmable. The Digestion Unit is Extremely Compact with a narrow footprint for optimum use of space on the lab bench. In compliance with GLP (Good Laboratory Practice), data can be printed or stored in a PC.

VELP digesters are suitable for a variety applications in food&feed, beverage (nitrogen, protein, Total Kjeldahl Nitrogen), environmental (COD, Total Kjeldahl Nitrogen), chemical and pharmaceutical (organic nitrogen) industries, in according with a variety of International Standards (such as AOAC, ISO, EPA, DIN etc.).

In order to neutralize the fumes produced during the digestion, DKL 20 should be combined with a proper Aspiration Pump and Fumes Neutralization System. VELP suggests combining DKL 20 with JP Pump and SMS Scrubber.
