Why the Long Neck on a Kjeldahl Flask
The Kjeldahl method for nitrogen determination involves digesting a sample in concentrated acid at high temperature, a step that can produce vigorous bubbling and fuming. The long neck on this flask helps contain splashing during digestion, and the borosilicate construction gives the thermal-shock resistance needed for sustained heating on a digestion block or burner.
