Description

KjelDigester K-449: The Ultimate Solution for Kjeldahl Digestion

The KjelDigester K-449 is a state-of-the-art laboratory device designed to optimise Kjeldahl digestion processes, an essential method for determining nitrogen in various samples. Thanks to its technology, this equipment can process up to 120 samples per day, reducing mineralisation time to just two hours. This significant time saving is made possible by rapid temperature rise and accelerated mineralisation, making it an indispensable tool for laboratories requiring fast and accurate analyses.

The KjelDigester K-449 stands out for its high level of automation, which makes it fully compatible with the KjelMaster system. This compatibility enables unrivalled analysis throughput while ensuring optimum accuracy and reliability. The device also complies with official regulations (AOAC, ISO, EN), ensuring reproducible and reliable results. This compliance is essential for laboratories that must adhere to strict quality and safety standards.

One of the key features of the KjelDigester K-449 is its automatic lifting system, which allows for unattended operation. This feature, combined with the ability to program temperature and time profiles, enables efficient sample management. Operators can plan digestion cycles in advance, reducing the need for manual intervention and increasing overall laboratory efficiency.

In addition, the KjelDigester K-449 is equipped with an improved sealing system, which ensures efficient extraction of harmful fumes. This feature is crucial for protecting the operator and the environment from the acid vapours generated during the digestion process. The individual sealing system for each sample tube allows acid vapours to be transferred efficiently to the K-415 Scrubber, ensuring maximum protection.

The KjelDigester K-449 is also designed to be practical and ergonomic. The suction module, equipped with two handles and magnetic supports, ensures a firm and secure hold. The collection tray can be stored in its holder during mineralisation, extending the service life of the block and accessories. This ergonomic design makes the device easy to handle and reduces the risk of accidents or damage to equipment.

The KjelDigester K-449 is a high-performance laboratory device, ideal for laboratories requiring fast and accurate analyses. With its features and compliance with international standards, it offers a complete solution for Kjeldahl digestion, ensuring reliable and reproducible results. Whether for routine analyses or complex research, the KjelDigester K-449 is a wise investment for any modern laboratory.
