Our UFT Series Tablet Friability Tester is the requisite instrument in detecting dissolution of tablets, capsules, etc. All of our lab instruments are designed and manufactured in accordance with USP specifications. The UFT-2 Friability Tester is comprised of dual drums rotated at a fixed speed of 25 rpm. Alternatively, the UFT-1 has variable speed from 20 ~ 90 RPM. The standard friability drum has an inside diameter of 286 mm and a depth of 39 mm and is fitted with a curved baffle which subjects the tablets to be tested to a drop of 156 mm.
Friability Testing measures the potential percent weight loss of compressed tablets by replicating the rigorous environmental conditions that tablets are subjected to during the manufacturing, packaging, and distribution processes. Tablets need to be hard enough not to break up in the bottle but friable enough that they disintegrate in the gastrointestinal tract.
In a friability test, samples are counted and weighed, then tumbled in the rotating drums with baffles. Friability is determined when the process is stopped by weighing the samples again and calculating the difference between the before and after weight. Friability should not exceed 1%, which is considered the ideal percentage.
