Tablet Friability Apparatus

The Tablet Friability Apparatus is an essential quality control instrument designed to measure the resistance of uncoated tablets to abrasion and breakage during handling, packaging, and shipping. The test involves placing a pre-weighed sample of tablets in a drum with a specific internal curvature. The drum then rotates at a set speed for a predetermined number of revolutions, causing the tablets to gently tumble and rub against each other and the drum’s walls. After the test, the tablets are re-weighed, and the percentage weight loss, or friability, is calculated.

This simple yet critical test is a standard requirement in pharmacopeias (USP, EP) and is used extensively in pharmaceutical manufacturing to ensure tablet durability and structural integrity. A low friability value indicates a hard, durable tablet that can withstand the stresses of production and distribution without generating excessive dust or fragments. By providing a reliable and standardized measure of mechanical strength, the friability tester is indispensable for formulators and quality assurance teams in guaranteeing product quality, patient safety, and compliance with industry regulations.
