KjelDigester K-446 / K-449 – High-Efficiency, Proven & Safe Digestion
The KjelDigester K-446 / K-449 is engineered for laboratories that demand speed, accuracy, and operational safety. Its highly efficient heating and cooling significantly reduce digestion time—saving up to two hours per batch. The 20-position rack can be directly transferred to the KjelSampler, ensuring a smooth and efficient workflow. With features such as automatic lift, delayed start, and unattended operation (K-449), users gain maximum flexibility and productivity. Advanced programming of time and temperature profiles, along with full Scrubber K-415 control, delivers precise and reproducible digestion results.
Built on proven technology, the system is fully compliant with AOAC, ISO, and EN standards. Accurate temperature control and improved thermal homogeneity ensure consistent digestion across all samples. Safety and convenience are further enhanced through improved sealing for effective fume transfer, magnetic suction module fixation, and a protective drip tray that extends the lifetime of the block and accessories while reducing waste.
