Tablet Friability Test Apparatus
Friability testing is a method, which is employed to determine physical strength of uncoated tablets upon exposure to mechanical shock and attrition and are able to withstand during their manufacturing, distribution and handling by the customer. Throughout pharmaceutical industry, friability testing has become an accepted technology and the instrument used in to perform this process is called Friabilator or Friability Tester. In friability test, samples are counted and weighted then tumbled in rotating drums with baffles, when the process is stopped; samples are moved out from the instrument, wiped-off dust and weighted again. The difference between the weight before and after the process is determined as Friability and should not exceed 1%, which is considered an ideal percentage. In some cases, where diameter of tablets is greater than 13mm, such tablets are tested on drums 10° tilted.
