Bulk and “ready-to-fill” format
Gx® bulk prefillable luer lock glass syringes 1.0ml standard are washed, sterilized, and filled by the customer. For this form, there is a division of labor between the primary packaging manufacturer and the pharmaceutical industry where we provide the unsterilized syringe bodies in flat trays (Rondo trays).
Gx RTF® needle syringes are washed, siliconized, pre-assembled with needle shields or tip caps and sterilized with ethylene oxide (EtO) by Gerresheimer Medical Systems. This means we deliver the prefillable glass needle syringe completely prepared for aseptic filling.
Gx RTF® luer lock syringe 1.0ml standard are packed in nests (100 nest, 10x10 or 160 nest, 10x16) for easy handling and filling. These nests are suitable for all usual filling systems.

Various options for siliconization
Siliconization is critical to ensure reliable function of prefillable luer lock syringes. It ensures optimal syringe performance for delivering medications. Thanks to the hydrophobicity of the silicon layer, potential interaction between the glass and the drug formula is reduced. As a standard, our prefillable glass syringes are spray-siliconized using diving nozzle technology in order to ensure an even coating with the smallest possible amount of silicone oil. We also offer our Gx® Baked-on RTF® glass syringes, which are patented in Europe and the USA for the packaging of sensitive biotechnological medications that may interact with free silicone oil droplets. In this procedure, a silicone oil emulsion is applied to the inner surface of the syringe body and subsequently thermally fixated on the surface by heating. This significantly reduces the number of free silicone oil droplets. Despite the considerably reduced amount of silicone oil, the prefillable syringes offer reliable hydrophobic properties and especially low breakout and gliding forces that remain stable throughout the storage period.
Advantages of the Gx Baked-on RTF® syringes

  • Reduced interaction risk between drug formulation and silicone oil
  • Drastically reduced amount of silicone oil droplets below the visibility threshold
  • Masking and inactivation of the glass surface
  • Standard-term stable, evenly distributed, and chemically inert lubricity coating
  • Very even break loose and gliding force profile
  • Ensures optimal functionality and drug formula stability over the period of medication storage
  • Patented in Europe and USA


Various possibilities for printing
For the individual printing of the glass syringe body of the prefillable luer lock syringe 1.0ml standard we offer the most varied possibilities for printing such as metal-free paints, ceramic printing on glass, various designs of graduation, dose mark, various colors and other options on request.
Syringes as a complete system Gx® bulk and Gx RTF® prefillable luer lock syringe 1.0ml standard can be provided with glued in cannula can be provided as a complete system with plunger stopper, plunger rod and backstop.
