Kjeldahl Analyzer

High-performance automatic and semi-automatic Kjeldahl analyzers, digestion blocks, and distillation units designed for precise nitrogen and protein determination in food, agriculture, and environmental samples.

Nitrogen Analysis

Laboratory Kjeldahl Analyzers

Kjeldahl Analyzers are vital analytical workstations designed to automate the classic Kjeldahl method for determining nitrogen and protein content in organic substances. The method remains the global standard for assessing protein levels in agricultural products, animal feed, soil, food formulations, and wastewater discharges.

At DNA Dynamics, our Kjeldahl platforms include high-speed graphite digestion blocks, automated steam distillation units, and fully-integrated titration systems. Built with chemical-resistant PEEK and stainless steel components, automated safety window locks, and intuitive touchscreen programming, they optimize sample runs while ensuring absolute protection against hot acids and hazardous alkali vapors.
