In these the desired active pharmaceutical ingredients are added. In order to varify in regards to quality management that the desired amount of pharmaceutical ingredients was added in a tablet, an element analysis is performed. Hereby the tablet is pulverized. With the FRITSCH Mortar Grinder PULVERISETTE 2, 10 - 20 tablets are ground. In order for no ingredients to disappear due to the application of energy, the mortar mill is the proper choice. The grinding action of the pestle does not increase the temperature during the grinding process. The pharmaceutical ingredients remain constant. After a grinding duration of 1 - 5 minutes a homogenous powder is achieved with a particle size of < 100 µm. We recommend grinding sets made of agate or hard porcelain. Even dragées or coated tablets may be ground. But here sometimes the coating is not ground perfectly.
