PTF1DR and PTF3DR Automated Single or Three Drum Friability Tester


The PTF1DR (single drum) and PTF3DR (three drum) FriabilityTesters are multi-drum automated tablet friability testing instrument that are fully compliant to USP <1216> and EP <2.9.7>.  Friability testing is a quality control test used to test the durability of tablets during transit. This involves repeatedly dropping a sample of tablets over a fixed time, using a rotating drum with a baffle. The result is inspected for broken tablets, and the percentage of tablet mass lost through chipping is calculated.

These models feature a unique loading window in the friability drum. The tested samples are automatically discharged into individual stainless steel collectors without having to remove the drums from their axis. They also offer direct connection to a Mettler or Sartorius analytical balance for weight results before and after a test run with printer connection to receive a full test report.
