Gx RTF® prefillable luer lock glass syringes are washed, siliconized, pre-assembled with tip caps or the patented Gerresheimer Gx TELC® closure systems and sterilized with ethylene oxide (EtO) by Gerresheimer Medical Systems. This means we deliver the prefillable glass luer lock syringe completely prepared for aseptic filling.

Gx RTF® syringes are packed in nests for easy handling and filling. These nests are suitable for all usual filling systems. Gx RTF® syringes are nested by:
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
One problem associated with syringe use is that traces of tungsten or tungsten residues can leave residue behind in the bore when the syringe cone is shaped. Especially for drug products based on biotech derived drug products, our customers therefore require prefillable luerlock syringes that ideally exclude the possibility of contamination with tungsten.
With the development of an innovative production technology registered for patent, we have been able to address this requirement and create 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 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 luerlock syringes for the packaging of especially sophisticated medications with this new technology.
The Fresenius Institute conducted a study confirming that no ceramic residue can be detected in the syringe. A biocompatiblity study also verifies that the ceramic material is not cytotoxic.

For reducing tungsten residues for standard luerlock syringes we can offer on our standard manufacturing process of syringes an additional cleaning step using a washing machine following by the forming of the glass.
Through the combination of water and ultrasonic bath, our internally developed, multi-stage treatment system thereby reduces not only the the tungsten load dramatically by 90% on average , but also brings down the load of glass particles by up to 90 percent.
Gerresheimer Medical Systems offers the two primary materials used in the pharmaceuticals industry: primary packaging made of glass and plastics as well as customized drug delivery systems and medical devices made of plastics. Our Center of Excellence for prefillables glass syringes and glass cartridges in Bünde is working together closely with our plastic specialists in our Technical Competence Centers in Wackersdorf (Germany), Peachtree City (USA, GA) and Dongguan City (China). In this way we can combine our know-how in the areas of glass and plastics.
This gives our customers the possiblity to develop, together with our experts for glass and plastics, a distinctive syringe, an application system or a combination product which is matched to a specific agent, area of use and company brand. One convincing example of the cooperation of our experts for syringes with our specialists for plastics is our offering of plastic syringes developed and manufactured by Gerresheimer Medical Systems.
