As no physical sample, picture sample, product code, or lot number was provided for evaluation by our quality engineer team, a complete investigation could not be performed.Phaseal needles are designed to reduce the coring tendency.If coring comes from membrane: a) human error: performing multiple injections on the membrane could lead to fragmentation.B) machines: if membrane is excessively welded, consistency is higher and elasticity lower, and once it is pierced by the needle, it could provoke membrane fragmentation.C) materials: needles.If coring comes from rubber stopper: d)materials: rubber stopper.Quality of rubber stopper will impact the occurrence of particles.The larger the percentage of inorganic filler in the rubber stopper, the more often cores and fragments will be produced.Capping conditions have shown to have significant effect on coring tendency.The type of crimping device used as well as the sealing force will have an influence on coring.E) materials: needles.Design and dimensions of the needle influence the tendency for coring, especially regarding the production of larger cores, cut out from the rubber stopper by the needle edges.Phaseal needles are designed to reduce occurrence of coring.F) misuse by the user: if the user makes a bad connection or turn the protector on the cap of the vial rather than insert it vertically, the cannula of the protector because of the rubbing with the stopper of the vial may cause detachment of particles from the cap of the vial.It is recommended to carefully follow the instructions explained in the ifu.For every manufactured lot the laboratory technician made the particles fragmentation test according to the it-1730 procedure.The test is carried out within a in a laminate flow hood.Staff has to wear a lab coat, cap and gloves.In the description of the complaint, it is explained that the fragment/s found belong to the rubber stopper.Taking into account the lack of information it is no possible to confirm the root cause of the defect (bad quality of the rubber stopper, defect in the needle of the protector or in needle of other device attached, or misuse by the user).
