Application of the Kjeldahl flask without grinding

The Kjeldahl flask without grinding is used for mineralization of samples in concentrated sulfuric acid, which is the first stage of nitrogen determination using the Kjeldahl method. The long neck of the flask reduces sample loss and splashing during rapid heating with acid, and the borosilicate glass withstands high temperatures and contact with aggressive reagents. Resistance to hot water, acids and alkaline solutions allows the flask to be used in analytical laboratories of the food, agricultural and quality control industries. The capacity range from 50 to 1000 ml allows you to select the flask for the size of the mineralized sample.

Other flasks from the "other" group in Danlab's offer: Kjeldahl flask with cut, pear flask with cut, pear flask with DURAN glass cut, heart flask with cut and distillation flask according to Engler.
