Kjeldahl Nitrogen Determination Apparatus

Kjeldahl nitrogen determination apparatus supports accurate nitrogen and protein analysis across food, feed, agricultural, environmental, research and quality-control laboratories. John Morris Group supplies Kjeldahl equipment through our Food and Feed portfolio, with visible category support from Gerhardt, Labconco and Labfriend for teams needing dependable digestion systems, fume handling and B2B procurement support.

The visible range includes Kjeldahl digestion units with 8, 12, 16, 20 and 40 place formats, 100 ml, 250 ml, 300 ml, 400 ml and 500 ml vessel compatibility, fume collectors, sample racks and Gerhardt KJELDATHERM KT and KT-L systems. These products support Food and Feed, Laboratory, agricultural testing, dairy analysis, feed mills, university laboratories and commercial quality assurance teams requiring repeatable digestion before nitrogen or protein determination.

Choosing Kjeldahl Nitrogen Determination Apparatus For Protein Analysis

Choosing Kjeldahl nitrogen determination apparatus starts with the sample throughput, vessel size, digestion capacity, fume collection method, automation requirement and whether the laboratory needs a standard block digestion unit or a lift-assisted system. The visible category range includes multi-place digestion systems, Gerhardt KJELDATHERM units, sample racks, 250 ml, 300 ml, 400 ml and 500 ml tube formats, and fume collector configurations for demanding nitrogen and protein analysis workflows.

Digestion Capacity: Select 8, 12, 16, 20 or 40 place systems based on daily sample load and required batch throughput.
Tube And Vessel Size: Match 100 ml, 250 ml, 300 ml, 400 ml or 500 ml vessels to sample mass, acid volume and method requirements.
Fume Collection: Fume collectors help manage acidic vapours generated during Kjeldahl digestion workflows.
Lift-Assisted Systems: KT-L configurations can support safer and more ergonomic handling of hot digestion racks.
Food And Feed QA: Kjeldahl systems are widely used for nitrogen and protein determination in food, dairy, feed, agricultural and raw material testing.

Kjeldahl Digestion Units For Food, Feed And Laboratory Testing

Kjeldahl digestion units are used to prepare samples before distillation and titration steps in nitrogen and protein determination. Procurement teams should confirm sample type, digestion tube size, required number of positions, fume extraction setup, controller requirements, available power supply, bench space and compatibility with downstream distillation systems before ordering.
