Kjeldahl flask

A Kjeldahl flask is a specialized laboratory container used in the Kjeldahl method to analyze nitrogen content in samples like food, soil, or water. It’s a long-necked, heat-resistant glass vessel designed to withstand boiling and chemical reactions. The process involves digesting the sample with acids to convert nitrogen into a measurable form. The flask’s shape helps contain the reactions safely and efficiently, ensuring accurate results. It is an essential tool for determining protein levels and ensuring quality control in various industries.
