Thermal homogeneity and precision
The DK 6/48 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 6/48 Series guarantees accuracy and repeatability. Program your methods with digestion time and up to 4 temperature ramps through the intuitive digital display.
The DK 6/48 series perform batch digestion of up to 6 samples with 300 ml test tubes - Ø 48 mm, reducing the power consumption of 13% compared to the previous series.
Low energy consumption permit to have low costs for every single analysis and limit CO2 release.
Space saving design
The new design of the DK Series has been studied in order to let laboratories to save valuable space under the fume hood.
The DK 6/48 digestion units have very compact dimensions: the new aluminum heating block has been lowered as a consequence of the enhanced performance of the new Series.
The structure is manufactured from stainless steel studied and tested to assure a strong resistance to chemical or mechanical agents.
A new intuitive interface and protection
The new bright digital display provides maximum visibility and easy reading of the information. The inclination of the frontal panel protects it from the spillage and hot chemicals.
The usage of the instrument is controlled by only 4 keys: they allow an easy navigation through all the functions during programming or normal use.
The new grid ensures enhanced heating performances and protects the aluminum heating block and the tubes.
Fume Neutralization System
For application 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
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 CO
2
emissions
Money Saving: cost reduction for each analysis
Space Saving: the narrow footprint saves valuable laboratory bench space
