A tablet friability apparatus is a pharmaceutical quality control instrument with a rotating drum that tumbles tablets to simulate the mechanical stress of transport and handling. The apparatus consists of a motorized, transparent, acrylic drum that rotates at a set speed (around 25 RPM) and for a specific number of revolutions or time. Inside the drum, baffles or blades lift and drop the tablets, causing them to abrade against each other and the drum's surface. After the test, the tablets are removed, cleaned, and weighed to determine the percentage of weight lost due to chipping and breakage, indicating their durability and resistance to mechanical stress.
