A00000409 TMD 6 Mineralization System
Kjeldahl Digestion Units with 6-position aluminum heating block that offers an excellent thermal homogenity.
The DK 6 Digestion Unit VELP 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:
DKL digesters are fully automatic and immediately ready to use, as they consist of an aluminum heating block, a lift for automatic sample handling, suction hood, test tubes, test tube rack and drip tray.
The DKL series provides the operator with the ultimate technology that allows the laboratory technician to set up the analysis choosing from a library of 54 programs (30 pre-installed + 24 customizable), press START and walk away, boosting the lab productivity.
Ease of loading and unloading make the VELP DKL a pleasure to use when carrying out Kjeldahl analysis, and there is no need to handle the sample when the tubes are hot!
Premium performance with aluminum heating block
DKL extremely fast aluminum heating block is capable of reaching 420°C in just 20 min with best-in-class temperature stability.
The choice of premium materials and the powerful microprocessor guarantee precise block temperature with an accuracy of ± 0.5°C.
Even in terms of repeatability and conductivity, aluminum offers incredibly high performance!
DKL digesters drastically reduce the time needed to reach the digestion temperature according to the Kjeldahl method.
Compact design to save space in your lab
Everybody knows that there is never enough bench space in a laboratory, this is why we have made the DKL series as compact as possible.
The narrow footprint enables you to optimize bench space according to need: fit more instruments on the same lab bench or make different use of the extra space available.
Many labs prefer to perform mineralizations under a fume hood and the compact design of the DKL ensures a minimum use of precious space.
Intuitive operations
Enjoy the simplicity of the DKL’s display. Extremely bright, easy to read and practical with all the fundamental parameters available at a single glance.
Current temperature and ramp settings are clearly viewed on the display. Save up to 54 programs (30 pre-installed, 24 customizable) with up to 4 temperature ramps.
Monitor each stage of analysis as well as select options such as language (including ideograms).
Improved communication leads to improved efficiency.
Fume Neutralization System
For applications where the digestion process produces fumes, acid gases or corrosive substances, the below specific accessory is strongly recommended:
KS 1000Scrubber neutralizes all the fumes
TEMS™ Technology
The DKL series uses the unique TEMS™ technology, which provides significant savings.
Time: fast heating to 420 °C in just 22 minutes, excellent reliability, homogeneity and temperature accuracy.
Energy: reduced consumption by 35%, reduced CO2 emissions by reducing pollution.
Money: significant cost reduction for each analysis, increases the number of analyses without additional costs.
Space: compact profile, minimum use on the bench for optimal laboratory management
