DURAN 212312403 Kjeldahl Flask  Borosilicate Glass 100 mL

The DURAN 212312403 is a Kjeldahl flask with a nominal volume of 100 mL, manufactured from DURAN® borosilicate glass 3.3. This flask is engineered for use in the Kjeldahl digestion and distillation method, widely applied for nitrogen and protein analysis in food, feed, fertilizer, and environmental testing.

The round-bottom design ensures uniform heat distribution during digestion, minimizing hot spots and improving reaction efficiency. Constructed from borosilicate glass 3.3, it provides excellent resistance to thermal shock and aggressive chemicals such as concentrated sulfuric acid and alkaline reagents. Its narrow neck allows secure connection with digestion and distillation apparatus.
