  • It is time to have it run.
  • The tester stops automatically, immediately the process is completed.
  • You can take out samples from the drum after the tester stops.
  • After removal, go through with de-dust, weigh, and have friability calculated.

Double Drum Tablet Testing Device

You can run both abrasion and friability tests.  When the testing process is done, the machine discharges tablets automatically.

How does this testing machine work?

  • Prior to loading samples into drum, make sure they are prepared for loading and clean too. This helps to ensure there is no dust getting into the drum to cause issues of foreign increase in tablet weights.
  • The weighing scale needs to be modified to start from 0. You can then have sampling weighing done.
  • Ensure the testing time anticipated is well set.
  • Also set the revolution number.
  • Load all samples into drum through the discharging area.
  • Now you can run the testing machine.
  • When testing is done, the tester stops automatically.
  • The sample tablet will then be discharged into the collection tray.
  • You can now check, de-dust, weigh, and calculate samples.

 Triple Drum Tablet Friability Testing Machine

It has been designed to undergo both abrasion and friability testing methods.

How does this testing machine type work?

  • Begin by calibrating the machine. This should be done to enhance its outcomes.
  • Time mode setting is next.
  • Set the revolution mode.
  • Clean tablet samples.
  • Weigh tablet samples.
  • Load samples into drums one by one.
  • Cover all three drums and begin the testing process.
  • Wait for the machine to automatically stop. This will happen when test is done.
  • Wait for the collection tray to let out or go of the samples tested.
  • You can then have all checks, de-dusting, and other stuff done.
  • Wait for print outs to be automatically generated.
