Additional Information for Kjeldahl Flask
Kjeldahl flasks are a type of laboratory glassware used in the Kjeldahl method for determining the nitrogen content in organic substances. They are part of the supply class Laboratory Equipment And Supplies in the supply group Instruments And Laboratory Equipment.
The Kjeldahl method is a widely used technique in analytical chemistry for determining the nitrogen content in organic compounds, such as proteins, amino acids, and fertilizers. It involves digestion of the sample with concentrated sulfuric acid, which converts the nitrogen present in the organic compound into ammonium sulfate.
Kjeldahl flasks are specifically designed for this method and are made of borosilicate glass, which is resistant to the corrosive nature of the sulfuric acid used in the digestion process. They typically have a round bottom and a long neck, which allows for efficient heating and condensation of the reaction mixture.
The flasks are available in various sizes, ranging from small volumes for individual samples to larger volumes for batch processing. They are usually equipped with a ground glass stopper or a reflux condenser to prevent the loss of volatile components during the digestion process.
Kjeldahl flasks are an essential piece of equipment in laboratories performing nitrogen analysis and are commonly found in research institutions, quality control laboratories, and academic settings.
