Use of Tungsten in the Glass Syringe Forming Process


In the forming process of prefillable glass syringes tungsten pins are frequently used to form the bore of the syringes. Tungsten has been the material of choice due to its good physical and mechanical properties. In certain cases, tungsten and tungsten oxide residuals may cause visible protein aggregations after the syringe has been filled. This is a rare event and only very few liquid formulations are sensitive to the traces of the metal in the bore;. Nevertheless glass syringe manufacturers like Gerresheimer have addressed the problem and offer low tungsten as well as tungsten free syringes for sensitive applications.

Professional background of the speaker:

Bernd Zeiss, Dipl.-Biol. studied biology, microbiology and chemistry at the University of Göttingen, Germany. He works in the Gerresheimer Centre of Excellence for prefillable syringes as Manager Technical Support. His main areas of work are investigating possible interactions between syringe components and drug as well as the evaluation of innovations like COP syringes in comparison to glass. Bernd also carries out inhouse functionality studies on prefilled syringes and prepares technical documentation for customers called "Technical Bulletins".
