By Corning
Corning® Pyrex® Kjeldahl Nitrogen Distilling Apparatus

This Pyrex® 500mL distilling apparatus is used for determining nitrogen in organic compounds. This assembly includes a Kjeldahl flask specifically developed for this process and a Graham condenser with 10mm O.D. tubulations. Both the digestion and distillation stages can be performed in this flask. The assembly shown is the distillation stage, where the amount of ammonia, and hence, nitrogen, is established. The inlet tube allows the permanganate solution to be introduced after distillation. Supplied with an outer ST 29/42 joint on the flask and an outer ST 19/38 joint on the Graham condenser. Total height is 410mm; total width is 300mm; maximum O.D. is 97mm. For replacement Graham condensers, see Cat.No. 1-2540-200.
