FOSS · Kjeldahl: protein, digestion, and scrubbers
Kjeltec™ 9 Analyser
Automated Kjeldahl distillation, colorimetric titration and calculation module. Digestion is performed separately in a Digestor; a 20- or 60-sample autosampler is available for batch work.
Quick decision
Is this method right for your task?
Consider it when
Large laboratories with high sample volume and variation
We clarify before quoting
Sample types, required parameters and ranges, tests per shift, reference method, sample preparation and data requirements.
Another method may be better when
You need different parameters, measurement ranges, throughput, automation or confirmation against another reference method.
Best suited for
Large laboratories with high sample volume and variation

Implementation considerations
The final configuration depends on sample types, parameter ranges, throughput, accuracy requirements, and existing reference methods. Before proposing equipment, LabLog clarifies these factors and defines the supply scope, training, and method-verification plan.
How LabLog supports the project
- 01Capture requirements and compare suitable methods
- 02Configure the instrument, calibrations, and consumables
- 03Arrange official supply and commissioning
- 04Train operators in sample preparation and daily operation
- 05Provide service communication and repeat consumable supply
