The Kjeldahl Distillation Assembly is a laboratory setup used extensively in the Kjeldahl method, which is a popular technique for determining total nitrogen levels in a sample. This method finds application across multiple fields, including food, soil, and biological research. The assembly generally comprises a Kjeldahl flask, a reflux condenser, a distillation column, a receiver flask, and a heat source.

The Kjeldahl flask contains the sample for analysis, the reflux condenser facilitates condensation during reflux, the distillation column extracts nitrogen compounds, the receiver flask gathers the distillate, and the heat source provides necessary thermal energy for the distillation.

In the Kjeldahl method, a sample undergoes digestion with a strong base, followed by distillation of the resulting nitrogen compounds into an alkaline solution, and finally, titration to determine nitrogen content. The Kjeldahl Distillation Assembly is designed to carry out this process with precision and efficiency.
