Syringes with reduced tungsten residues

A tungsten pin is used to create the syringe bore in the standard glass forming process. When traces of tungsten or tungsten oxides remain in the bore area, medications based on biotechnologically manufactured active ingredients may have adverse reactions in rare cases.
To reduce tungsten residues in conventionally manufactured syringes, we offer our customers the option of subjecting the syringes to an additional cleaning step in a washing machine after the glass has been formed.
Through the combination of water and ultrasonic bath, our internally developed, multi-stage treatment system thereby reduces not only the tungsten load dramatically by 90% on average , but also brings down the load of glass particles by up to 90 percent.
