KjelDigester K-446 / K-449
More samples per day
The KjelDigester offers fast and safe digestion of up to 20 samples simultaneously. The fully automated model K-449 offers a convenient automatic lift for raising and lowering the sample tube rack and a programming mode so that all digestion methods can be saved. The manual K-446 is an entry level block digester with effortless manual control and manual rack handling. The sample tube rack of both digesters can be placed directly into the KjelSampler K-376 and K-377 for fully automated, high throughput nitrogen and protein determination according to Kjeldahl.
Features
Directly transfer the complete rack containing all sample tubes to the KjelSampler K-376 or K-377.
The suction module with two handles and magnetic connections guarantees a strong and secure hold. Store the drip tray in the holder during a digestion run.
Unprecedented sample throughput of up to 120 samples per working day thanks to the fast heating and accelerated digestion.
Safe and convenient operation with the automatic sample lift. Fully unattended digestion process through the programming of methods.
Reach even the lowest nitrogen levels with genuine BUCHI Sample Tubes. They have a wide diameter, constricted condensation zone, thick glass walls and can contain bigger volumes.
Individual sealing of each sample tube allows effective transfer of acid fumes to the Scrubber K-415 and gives maximum protection to the operator and the environment.
