Velp Scientifica F30100440 – DK 20 Digestion Unit (230V / 50-60Hz)

• 230V / 50-60Hz (Power: 2300 W)
• Digester only (support system, sample rack, suction cap, and drip tray, and test tubes not included)
• 20 positions for 250 ml test tubes, 42 mm diameter
• The aluminum heating block ensures high thermal homogeneity heating up to 450 C (842 F)
• Heating block temperature stability of ± 0.5°C

Kjeldahl Digestion Units with 20-position aluminum heating block that offers an excellent thermal homogeneity. 

The DK 20 Series digestion unit with an 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 20 Series guarantees accuracy and repeatability. The DK 20 series perform batch digestion of up to 20 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.

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.

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. 

DK 20 is a versatile digester suitable for Kjeldahl N/Protein applications and Chemical Oxygen Demand in the environmental industry. 

In order to use the DK 20 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 20 samples simultaneously.

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

• JP Pump aspirates noxious fumes
• SMS Scrubber neutralizes all the fumes

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
