The following fields were updated due to additional information: d10: device available for eval yes.D10: returned to manufacturer on: 2021-10-14.H6: investigation summary a photo and the affected sample were received by our quality team for evaluation.After evaluation, the team was able to identify the foreign matter as embedded contamination in the syringe tip.A review of the internal manufacturing device records and raw material history files for the reported lot number was performed and no recorded quality problems or rejections to this incident were found.The team was able to determine that the black mark observed in the tip of the syringe is a defect regarding embedded particles in the plunger.The embedded particle defect was produced in the screw of the injection molding machine.Due to the high working temperature (about 300ºc), different gases are produced inside the mold.During normal production, these gases are expelled through some conduits, outside the mold cavity.In this case, the expulsion was not done correctly, and some gases remained in the mold cavity and produce the burnt syringe piece.H3 other text : see h10.
