Product Overview
The quality of a crimp seal is strongly dependent on the right calibration of the crimping tool used to apply the closure to the vial. A too tight or too loose crimp will impair the quality of the seal. To maintain good results, make sure to re-calibrate your crimping tool regularly and check the quality of the seal every time you crimp.
