Flask, Kjeldahl with Joint

Constructed from premium borosilicate glass, this Kjeldahl digestion flask features a long neck with a precision ground‑glass joint for secure attachment of distillation and reflux assemblies. Its pear‑shaped body and uniform wall thickness ensure even heating and excellent thermal shock resistance during vigorous acid digestions. A reinforced flat base provides stable support on heating blocks or hotplates, while clear volume markings allow for precise sample measurement—ideal for reliable nitrogen analysis in food, feed and environmental samples.
