ST-14BS Pharmaceutical excipient nitrogen analyzer (4-hole)
The ST-14BS=ST-14B+ST-04C pharmaceutical excipient nitrogen analyzer mainly consists of two parts: an electric heating digestion furnace and a distiller.
ST-14BS pharmaceutical excipient nitrogen analyzer (also known as pharmaceutical excipient protein analyzer) is a series of products designed by our company based on the principle of Kjeldahl nitrogen analyzer, which complies with the 2020 Chinese Pharmacopoeia 0704 nitrogen analyzer method and 0731 protein content analyzer method. Mainly used to detect the protein content in test samples that do not contain inorganic nitrogen-containing substances or organic non protein nitrogen-containing substances.
