Evaporation residue: Based on the gravimetric method, the test liquid is evaporated to constant weight by heating to determine the mass of the residue. It is widely used in determination of material purity, moisture, stability, migration and other testing items in chemical, chemical reagents, pharmaceutical, medical devices, food, food contact materials and other industries. Water-insoluble matter: After the sample is dissolved, filtered, dried and weighed, the mass of water-insoluble matter is tested. It is widely used in the determination of purity, stability, solubility and other items in chemical, chemical reagents, pharmaceutical, food, water quality analysis and other industries. Residue on Ignition: The sample is ignited in high temperature and the residue is weighed to analyze the mass of non-volatile inorganic matter in the sample. It is widely used in the determination of purity, impurities, stability and other items in chemical, chemical reagents, pharmaceutical, food, environment, construction and other industries.
New
C840H Integrated Evaporation Residue Testing System is designed and produced based on the principle of gravimetric method measurement and testing standards for plastic packaging and chemical reagents, etc. It is suitable for the determinations of evaporation residue of food or pharmaceutical packaging, total migration of food contact or pharmaceutical contact materials or products, and evaporation residue of chemical reagents and purified water.
