At this meeting, we brought a number of products to the booth "E2 2323". Among them, there are not only classic products such as UV-Vis spectrophotometer, microwave digester and TOC total organic carbon analyzer, but also some new products such as microwave synthesis extractor and online TOC analyzer. Users who can't visit the site can feast their eyes on the following video.

On October 15th, 2021, the "2021 Pharmaceutical Quality Control and Inspection Technology Forum" sponsored by Liaoning Pharmaceutical Society ended successfully in Shenyang.
