A semi-automatic friability test system which includes display and documentation of revolution speed, test parameters, weight of the samples before and after the test as well as lost of weight in percent, is offered by the TDR 100 (for holding one drum) with an analytical balance connected (Mettler or Sartorius).

Similar to the TAR, loading an emptying in an container is performed through an opening in the friability drum which does not effect test results.

For large samples the drum can be adjusted to the USP/EP reguired 10° position.

During the test, revolution speed an remaining run time are shown on the illuminated 4-line LC display.
