ST-207CS Automatic Pharmaceutical Excise Protein Content
Determinator
ST-207CS Automatic Pharmaceutical Excise Protein Content
Determinator is a fully automated "nitrogen" (protein) analysis
system developed based on the classic Kjetliner nitrogen
determination technology and color method to determine the end
point. Its method and manufacturing are in line with GB/T
33862-2017 Fully (Semi) Automatic Kjetliner Nitrogen Determinator
and 2020 Chinese Pharmacopoeia 0731 Protein Content Determination
Method Method I Kjetliner Nitrogen Determination Method and 0704
Nitrogen Determination Method III Nitrogen Determination Method.
It is widely used in food processing, feed production, chemical
industry, soil and fertilizer, environmental monitoring, medicine,
agriculture, scientific research and teaching and other fields in
the determination of nitrogen and protein. It has the functions of
automatically adding diluted water, adding alkali, adding receiving
liquid, delayed distilling, measuring, calculating, printing, steam
flow regulating, fault self checking, etc.
