Double Drum Tablet Friability Tester PTF 300

Category: Brand:


PTF 300 is a triple drum tablet friability and abrasion test instrument. It is manufactured in compliance to the USP <1216>, EP <2.9.7> and JP <14> Pharmacopoeias. The instrument features an automated sample discharge at the end of a test and the possibility to connect an analytical balance.

One of the testing criteria for mechanical strength of tablets and cores according to the USP <1216>, EP <2.9.7>, JP <14> and other pharmacopoeia is friability and abrasion testing. During the process of coating, transportation and packing the tablet will lose some amount of weight. To measure this weight loss, the samples are counted and weighed. Then the friability test is performed following the individual monographs of the relevant Pharmacopoeia. The tablets are tumbled at each turn of the drum of the friability testing instrument by a curved baffle that extends from the middle of the drum to the outer wall.
