Bulk and “ready-to-fill” format
Gx® bulk prefillable luer cone glass syringes 1.5 ml 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® prefillable luer cone glass syringes 1.5 ml are washed, siliconized, pre-assembled with the closure systems Six Rib Tip Cap and sterilized with ethylene oxide (EtO) by Gerresheimer Medical Systems. This means we deliver the prefillable glass luer cone syringe completely prepared for aseptic filling. Gx RTF® luer cone syringes 1.5 ml are packed in nests (100 nest, 10x10) for easy handling and filling. These nests are suitable for all usual filling systems.

Closure system Six Rib Tip Cap
We offer a Six Rib Tip Cap as a closure system for our prefillable luer cone glass syringes.
EtO-sterilizable rubber formulas: Datwyler FM27, FM30, West 1883, 7025/65, 7028/55, other formulas available upon request.

Various options for siliconization
Siliconization is critical to ensure reliable function of prefillable luer cone glass 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. 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 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® syringe

  • Reduced interaction risk between drug formula 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 cone syringe 1.5 ml 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 cone syringe 1.5 ml can be provided with glued in cannula can be provided as a complete system with plunger stopper, plunger rod and backstop.
