Product Description
Laboratory Distillation Automatic Kjeldahl Nitrogen Analyzer
Introduction
NB9870 automatic Kjeldahl nitrogen analyzer is based on the classic Kjeldahl nitrogen determination method
developed automatic distillation-color method to determine the end point of "nitrogen" (protein) analysis system.
This product is a fully automatic product with automatic distillation and separation of samples and automatic titration
and analysis. It is especially suitable for research and development by scientific research institutions and industrial and
mining enterprises.
