DURAN 212315409 Kjeldahl Flask Borosilicate Glass 1000 mL

DURAN 212315409 Kjeldahl Flask Borosilicate Glass 1000 mL

The DURAN 212315409 is a Kjeldahl Flask Borosilicate Glass 1000 mL manufactured from high-quality DURAN® borosilicate glass 3.3, a material renowned for its excellent thermal resistance, chemical durability, and mechanical strength. This flask is specifically designed for Kjeldahl digestion and distillation procedures, which are essential in nitrogen and protein determination for analytical, food, agricultural, and environmental laboratories.

Its round-bottom design ensures uniform heat transfer during digestion, minimizing hot spots and enhancing efficiency in sample breakdown. The narrow neck allows safe handling and secure attachment to condensers or distillation equipment. With a uniform wall thickness, the flask is capable of withstanding repeated heating–cooling cycles and exposure to concentrated acids such as sulfuric acid, commonly used in Kjeldahl digestion.
