2.0 DESCRIPTION OF FAB-2S FRIABILITY TESTER
Logan FAB-2S Friability Tester is a double-drum Tablet Friability Test instruments, manufactured in
compliance to the USP, Europe, and other Pharmacopoeias. One of the testing criteria of mechanical
strength of tablets and cores is Friability and Abrasion testing. During the process of coating,
transportation, packing …etc. the tablet will lose some mass. To measure the mass loss the samples are
counted and weighed. Thereafter the Friability test performed following the individual monographs of
the Pharmacopoeia. When finished the samples have to be dusted and weighed again. Actually the
difference between the weight before and after the test is determined as Friability, which usually should
not exceed 1%.
The standard Friability drum causes the samples to roll and fall during the test while the abrasion drum
continuously stresses the sample by abrasion of lamellas. FAB-2S Friability Tester can be used 1 or 2
drum. A noiseless gear motor rotates the drums with a variable speed of 25-70 RPM that programmed
by users. The actual drum is made from Plexiglas and separated into two parts, the drum body and a
removable cover, opened to fill, discharge and clean the drum inside when required. The instrument
itself is made from high quality metal which meets in full the actual GLP requirements.
FAB-2S FRIABILITY TESTER includes the following:
•Main Drive Unit
•2 Drums (L & R)
•2 Drum Nuts (L & R)
