Digestion Furnace DF Series
Automatic Kjeldahl Apparatus Working Principle:
The KA-DNII kjeldahl apparatus adopts an automatic steam control generator, which, together with the liquid level regulator, can output steam steadily within tens of seconds. The apparatus is designed and manufactured by the international Kjeldahl method of nitrogen determination. The alkaline liquid flows through the distillation tube into the quantitative elimination tube so that the ammonia immobilized in the acid liquid is volatilized under alkaline conditions.
The vapor generated can distill the sample under alkaline conditions, causing the ammonia to volatilize completely. The volatilized ammonia is condensed by a condenser and completely immobilized in boric acid, then titrated with a standard acid. At the endpoint, the nitrogen content is calculated and then multiplied by the protein conversion factor to obtain the protein content.
Automatic Kjeldahl Apparatus Feature:
The microcomputer control is very intelligent, including automatic distillation control, water addition, water level control, and water stopping.
The amount of boric acid and alkali, as well as the time of distillation and absorption process, can be set by yourself to meet the needs of professional users.
Automatic power-off in case of a system malfunction, safety door device for digestion pipeline, water shortage alarm, water level detection, etc. ensure safe operation.
Standard configuration without digestion furnace, but can be equipped with optional digestion furnace.
