H.6.Investigation: no photos or physicals samples that display the reported issue were provided for investigation.A device history was performed and found no no-conformances related to the reported issue during production of lots 1704010 and 1910111.Four retained samples of each lot were used for additional evaluation.Two samples of lot 1704010 and two of lot 1910111were connected to a standard 32mm vial using the m12 assembly fixture, in all instances the protectors properly fit the vial and no leakage was observed.The additional two samples of each lot where then connected to a vial of piperacillin/tazobactam using the m12 assembly fixture.In all samples it was noted that the protector was not to securely fit onto the vial and a leakage between the protector and vial was observed.Product is visually and functionally tested throughout the manufacturing process to ensure the quality and functionality of the device, including leakage testing.Test results were reviewed for the reported lots, all product met required specifications.Based on the available information we are not able to identify a root cause related to the manufacturing process at this time.It would appear the failure is related to the cap from the vial that was used which did not allow for a secure connection between the vial and protector.
