Product applications
It is suitable for agricultural scientific research units and can be used for the analysis of nitrogen content in organic matter, such as digestion reaction and ammonia distillation.
When using a nitrogen flask, it is necessary to wash and dry it first, weigh the measured object with aluminum foil, wrap it and put it in the flask, add sulfuric acid to heat, so that the measured object reacts with sulfuric acid to generate ammonium sulfate (Ensure the flask is tilted at a 45 degree Angle during heating to prevent the solution from boiling over).
