Labbox Kjeldahl digestion device, KJD10
The Labbox Kjeldahl digestion device is an advanced solution for precise and efficient nitrogen determination in a wide range of laboratory applications. This device is used particularly in areas such as quality control, food research or environmental analysis and impresses with its fast heat-up time and precise temperature control. Compared to conventional digestion devices, it offers infrared heating technology, which not only allows for even heating, but also ensures durable and corrosion-resistant processing.
Reliable technology for efficient digestion processes
This generation of appliances is characterized by modern graphite infrared heating, which reaches the desired temperature much faster and more evenly than conventional heating methods. The system reaches temperatures of up to 400 °C in just 25 minutes. This advanced heating method is also virtually immune to corrosion thanks to its antioxidant surface. For laboratories working with aggressive chemicals, this feature is a decisive advantage as it extends the system's service life and reduces time-consuming maintenance work.
Essential features at a glance:
- Graphite infrared heater with up to 450 °C
- Reaches 400 °C in around 25 minutes
- Accuracy of ±1 °C for reproducible results
- 20 storable programs for individual digestion processes
- 5.7-inch color display for clear and intuitive operation
- 20 heating points for 300 ml test tubes
- 1 year warranty
In addition to this core data, further functions are integrated to enable safe and time-saving work. The device has an alarm for critical temperatures and offers automatic overheating protection, so that both the user and the valuable laboratory environment are protected in the best possible way. Corrosive vapors are released during operation, which is why the use of a suitable extraction system is recommended. A suitable system such as the KJDL-A01-001 is predestined to neutralize aggressive residual gases and maintain a constant negative pressure in the system. This extraction system is characterized by a triple filter system that reliably prevents toxic vapours or liquids from escaping unintentionally. In addition, robust PTFE materials are used for the hose guide and pump to prevent the ingress of chemicals and maintain hygiene in the laboratory.
To round off the digestion process, we recommend using the corresponding Kjeldahl DTU3-042-*** test tubes. They can hold up to 300 ml of reaction solution and are specially designed for high heat and chemical resistance. In addition, catalyst tablets (such as the KJDL-CAT-250) are a useful option to further increase the speed and efficiency of Kjeldahl digestion.
The robust and durable design makes the device suitable for a wide range of applications:
- Food analysis (e.g. protein content in dairy products, meat or cereals)
- Environmental laboratories (determination of nitrogen compounds in water or soil samples)
- Pharmaceutical research (quality control, active ingredient analyses)
- Chemical industry (process control, research and development)
The device is operated via a color 5.7-inch touchscreen, on which the individual temperature program operation, the desired final temperature and the heating rates can be precisely set. Thanks to the 20 storable digestion programs, recurring experiments can be automated and easily reproduced. This speeds up work processes in the laboratory and reduces the risk of tedious manual errors.
The device consumes a voltage of 220 V ±10 % / 50 Hz with an output of 3600 W. With its CE conformity status, it meets current safety and quality standards. It is also marketed under the LBX INSTRUMENTS brand, which is known for its reliable and innovative laboratory solutions.
Certifications and standards
This infrared digestion device meets the quality and safety requirements of many laboratories worldwide. CE conformity in particular guarantees that important standards for machine and EMC safety are complied with. In addition, an antioxidant treatment of the graphite is incorporated into the development to ensure long-term safety and durability.
Application examples
- Food quality analysis: to determine the protein content in meat products, dairy products or cereals
- Environmental research: Analysis of nitrogen compounds in river or groundwater samples, for example to determine pollution from fertilizers.
- Pharmaceutical laboratories: testing active ingredients and evaluating chemical syntheses in the research sector.
- Chemical industry: process monitoring as well as research and development in the production of polymers, adhesives or fertilizers
Frequently asked questions (FAQs)
How does the temperature control work?
The appliance has an integrated temperature control, which uses a sensor and control system to precisely maintain the set temperature in a range from room temperature +5 °C to 450 °C.
Can the appliance be operated with different test tubes?
Yes, but it is recommended to use high-quality Kjeldahl test tubes made of a material suitable for high temperatures, such as the DTU3-042-*** series.
What to consider when operating with corrosive chemicals
An extraction system such as the KJDL-A01-001 prevents aggressive gases from escaping uncontrolled into the laboratory environment. At the same time, it ensures sufficient negative pressure and prevents damage to the device.
How does the programming of the digestion profiles work?
Up to 20 programs can be saved via the 5.7-inch color display. Individual heating rates and temperature levels can be configured in just a few steps.
What type of catalyst tablets are recommended
KJDL-CAT-250 is commonly used as they are specially formulated for the graphite heating system. They speed up the chemical conversion and help to achieve consistently reliable results.
Conclusion
This infrared digestion device impresses above all with its modern heating system, intuitive controls and long-lasting corrosion resistance. Thanks to many individual parameter settings, a wide variety of sample types can be analyzed precisely. Together with the recommended test tubes, catalyst tablets and a suitable extraction system, a highly efficient, safe overall package is available for laboratories that do not want to compromise on accuracy and reliability.
