Labthink introduces the C850M Integrated Water Insoluble Matter Testing System and the C850H Integrated Water Insoluble Matter Testing System, designed for the precise determination of water-insoluble matter in chemical reagents and pharmaceutical excipients.
Both systems use the gravimetric measurement method and are developed in accordance with GB/T 9738, pharmacopoeial requirements, and other relevant testing standards. They provide a reliable testing solution for laboratories seeking to evaluate material purity and quality.
During testing, the sample is dissolved in water, and the insoluble matter is separated through filtration. The residue is then washed to remove the remaining soluble components, dried, and weighed using a balance. This process enables accurate determination of the water-insoluble matter content.
