The glass digestion tube is a laboratory instrument used in chemical analysis to determine the total nitrogen content of samples of food, feed and other materials. These tubes are manufactured from borosilicate glass 3.3 and have the following characteristics
? Round bottom.
? Mouth with rim.
? Outside diameter: 42 mm.
? Length: 300 mm.
Their thick, uniform walls make them highly resistant to both chemical agents and high temperatures.
Compatible with Tecator and other digester systems.
The digester tube is used in the Kjeldahl digestion process, which involves digesting the sample with concentrated sulphuric acid and catalysts, followed by distillation and titration of the ammonia released during the digestion. The tube provides a safe and robust medium for sample digestion, which is essential for accurate results in chemical analysis.
It is essential for the determination of total nitrogen in laboratory samples, and its design and materials ensure its ability to withstand aggressive chemical and thermal conditions.
