VELP DK 6 Digestion Unit

Thermal homogeneity and precision

The DK 6 Series digestion unit with aluminum heating block ensures high thermal homogeneity heating up to 450 °C. The temperature of the block is constantly controlled by a microprocessor and is extremely stable, homogeneous and precise: ±0.5°C at all selectable temperatures.

The DK 6 Series guarantees accuracy and repeatability. The DK 6 series perform batch digestion of up to 6 samples with 250 ml test tubes - Ø 42 m, reducing the energy consumption (-13% compared to the previous series). Low energy consumption provides lower costs of analysis and limits CO2 release.

Space saving design

The design of the DK series has been carefully engineered to allow laboratories to save valuable space under the hood.

DK Digesters have very compact dimensions: the new aluminum heating block has been lowered and the vertical proportions allow to free precious space in the laboratory.

The structure is made of stainless steel that has been specifically designed and tested to ensure strong resistance to chemicals and mechanical stress.

The aluminum block protection grid provides enhanced heating performance and protects the heating block from splashes and chemicals.

Easy-to-use with the intuitive digital interface

The bright digital display provides maximum visibility and easy-to-read information.

The instrument is operated with 4 keys to navigate the menu options and program the digestions in a simple and fast way.

Through the intuitive graphic display it is possible to set up to 20 methods with 4 temperature ramps.

Acoustic signals inform the operator of the completion of the analysis facilitating the daily use of the digester.

The inclination of the front panel protects it from chemical spillage at high temperatures.

COD digestion with DK 6

DK 6 is a versatile digester suitable for Kjeldahl N/Protein applications and Chemical Oxygen Demand in the environmental industry.

In order to use the DK 6 for COD (Chemical Oxygen Demand) is necessary to configure it by adding a different support system able to manage all the glass required for the COD analysis for processing 6 samples simultaneously.

Trace Determination of Heavy Metals

The DK 6 and TMD 6 are the reliable solution for digestion with aqua regia (nitrohydrochloric acid) in order to determine the acid-soluble proportion of metals in sewage sludges, sediments and soils In accordance with official methods (DIN 38414-S7 standard).

• Water-jacketed condensers of TMD 6 retain all Hg, Cd, Pb, Cr, Cu, Zn, etc.
• TMD 6 is composed of high quality glass components with supports for DK 6
• Excellent accuracy and precision with a temperature homogeneity of ± 0,5 °C
• Space saving design
• Intuitive interface
• TEMSTM Technology

Fume Neutralization System

For applications where the digestion process produces fumes, acid gases or corrosive substances, the below specific accessory is strongly recommended:

• KS 1000 Scrubber neutralizes all the fumes

TEMS™ Technology

DK Series Kjeldahl digestion units work with the innovative TEMS™ benefits, for huge savings.

Time Saving: rapid heating reduces wasted time
Energy Saving: limited energy consumption thus cutting CO2 emissions
Money Saving: cost reduction for each analysis
Space Saving: the narrow footprint saves valuable laboratory bench space
