This Kjeldahl trap borosilicate glass adapter features two standard taper 24/40 male socket joints. It stands 7-3/8 inches tall. The 75° angled descending arm is 4 inches long. This is the same Kjeldahl adapter used in our NC-11663 24/40 Distillation Apparatus.
Kjeldahl traps are used to catch splashes from material being boiled and allow only vapors to enter the distillation column.
