This specification covers the design and dimensional requirements for the digestion and distillation apparatus used for the microdetermination of nitrogen by the Kjeldahl method, and modifications thereof at atmospheric pressure. This apparatus is comprised primarily of digestion flasks, micro Kjeldahl digestion rack, one-piece model distillation apparatus, and Pregl (Parnas-Wagner) type distillation apparatus.
