COR-5420-300 Corning 5420-300 PYREX 300mL These flasks are used for the determination of nitrogen by the Kjeldahl method. They have extra long necks that act as air condensers during the digestion stage and reduce entrainment during the distillation stage. The Kjeldahl flask is attached to a water condenser and is heated to boil off the NH 3 gas from the digest. The tip of the condenser is submerged in a flask of acidic receiving solution, either standard acid or boric acid solution, to again trap the distilled NH 3 in receiving solution.

Environmental Standards; Food The Kjeldahl method subjects flasks to severe chemical and thermal abuse. The Kjeldahl flasks we supply in our Pyrex® and Quickfit® product ranges are manufactured from Pyrex® borosilicate glass for optimum chemical and thermal shock resistance. Similar to the reaction flasks, the distillation flasks usually have only one narrow neck and a ground glass joint and are made of thinner glass than the reaction flask, so that they are easier to heat. They are sometimes spherical, test tube shaped or pear-shaped, also known as Kjeldahl Flasks, due to their use with Kjeldahl bulbs. · Place the sample into a digestion flask.
