US and European Pharmacopeias define tests for the friability (ease of crumbling) and abrasion resistance of uncoated tablets that are important components of overall product quality and stability. These tests involve tumbling them in drums for defined durations and at specified speeds and number of revolutions (typically 100).
The friability test does also help to reveal potential capping, chipping and delamination issues. It is a very important observation required of the technician.
CHARLES ISCHI AG - OSD Testing Technology offers the AE-series of tablet Friability & Abrasion Testers that allow these tests to be carried out easily and precisely. Made in Switzerland.
Abrasion & Friablity Testers
The abrasion and friability tester consists of one or two test stations. If required, test drums can be equipped to test for wear due to rolling and falling or to test the abrasion of tablets, tabletcores, granules etc.
The tester meets all the latest requirements of the European & US Pharmacopoeia, GMP and GLP.
Friability & Abrasion of tablets
Friability and abrasion testing is used to test the durability of tablets during the production and packaging processes. A sample of tablets is falling or rolling over a fixed time, using rotating drums with different shovels. The result is inspected visually for broken tablets and the percentage of tablet weight lost.
