FOSS · Kjeldahl: protein, digestion, and scrubbers

Kjeltec™

Kjeldahl distillation systems for nitrogen determination. The complete method also requires a separate Digestor; the titration configuration is selected for throughput and the applicable standard.

Best suited for

Laboratories at dairy, meat, and grain facilities, regulatory bodies

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
