It is imperative for pharmaceutical manufacturers to verify their capping processes and ensure the seals are seated properly to prevent leaks. One such company in Florida was unfortunate enough to experience this issue first hand. This drug manufacturer had to recall more than 8,900 cases of oxycodone1 because their product showed excess lidding material accumulation between the seal of the container and the cup, so the lid did not seal properly2.
These types of failures can easily be prevented by using release torque and application angle testing. So, what’s the secret of Mesa’s measurement technique?
With a highly sensitive strain gage-based torque transducer, a 2000 CPR rotary encoder and proprietary pressure controlled closure and bottle gripper designs, our servo-driven automated torque tester can accurately detect both small and large changes in the torque and angle during the removal of a closure.
