A Tablet Friability Apparatus is a quality control instrument for testing the mechanical strength of tablets. Key specifications include a transparent acrylic drum with a specific diameter (283–291 mm) and depth (36–40 mm), an internal baffle to tumble tablets, a rotation speed of 25 ± 1 rpm, and a provision to tilt the drum. Modern apparatuses often feature LED/LCD displays, digital revolution counters, automated discharge, and programmable timer or rotation settings for precision and ease of use.
