Glass syringes for the most sophisticated, biotech derived drug products

Metal-free glass syringes

One problem associated with syringe use is that traces of that traces of tungsten or tungsten oxides can remain in the bore when the syringe cone is formed. Some drug products react sensitive to tungsten, therefore we offer a completely metal-free glass syringe.

With the development of an innovative production technology registered for patent, we have been able to address this requirement and created a metal-free 1 ml long Gx RTF® Luer lock syringe that is ready for series production. This process can also be transferred to other Luer lock syringe sizes or to Luer cone syringes of various sizes at any time. The pin used to shape the cone with our new technology is not made of conventional tungsten or an alternative metal, but of a special ceramic. External studies confirm that we can manufacture residue-free syringes for the packaging of especially sophisticated medications with this new technology.

A study conducted by Gerresheimer confirms that no ceramic residue can be detected in the syringe. A biocompatiblity study also verifies  that the ceramic material is not cytotoxic.

  • The pin used to shape the cone is made of a special ceramic
  • 1 ml long Gx RTF Luer lock syringe commercially available, other sizes on request
  • The process is also applicable to all Luer cone syringes
  • The Fresenius Institute conducted a study confirming that no ceramic residue can be detected in the syringe
  • Not cytotoxic acoording to ISO 10993-5
