UDK 159 Automatic Kjeldahl Analyzer

April 30, 2024


The UDK 159 Automatic Kjeldahl Analyzer is a piece of laboratory equipment used for determining nitrogen content in organic compounds, particularly in samples like food, soil, and wastewater. The Kjeldahl method involves digesting the sample with concentrated sulfuric acid, which converts nitrogen into ammonium sulfate. Then, this ammonium sulfate is distilled and the ammonia produced is captured in a known volume of acid, which can be titrated to determine the nitrogen content.

The UDK 159 automates this process, making it more efficient and accurate compared to manual methods. It typically includes features such as automated sample digestion, distillation, titration, and result calculation. These analyzers are often used in various industries such as food and beverage, environmental testing, pharmaceuticals, and agriculture for quality control, research, and regulatory compliance purposes.
