Gx® bulk and Gx RTF® format

Packaging of bulk syringes in Rondo trays in clean room GMP class D

Gx® bulk needle syringes 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).

Packaging of Gx RTF® glass syringes in nests — Packaging of Gx RTF® glass syringes

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® 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:

100 nest (10x10) for 0.5 ml, 1.0 ml long and 1.0 – 3.0 ml
160 nest (10x16) for 0.5 ml und 1.0 ml long

Syringe sizes from 0.5 ml to 2.25 ml (additional formats upon request)

The high-quality prefillable glass syringes are produced from type I glass. The prefillable needle syringes are available in syringe sizes from 0.5 ml to 2.25 ml (individual solutions on request).

Needle 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.

Core of a washing machine for the cleaning of syringes in order to reduce glass and tungsten particles

For reducing tungsten residues for standard needle 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.

Prefillable COP plastic needle syringes for avoiding tungsten residuals

A further option is the use of plastics like Cyclo Olefin Polymers (COP) as syringe material. The production process has no potential for tungsten residuals. Our prefillable needle syringes of COP are therefore also exceptionally well-suited for the packaging of highly sensitive medication.

Method for detection and limit value for glue leachables

Method for detection of glue leachables for prefillable needle syringes — Gerresheimer offers a method for detection and a limit value for glue leachables

Syringes with glued in needles have lower loads of tungsten residues because the UV-hardened glue seals the sensitive syringe area. However, glue residues can nonetheless leach from the glue. We have optimized our production process reducing these residues, and additionally we offer a method for detection and a limit value for glue leachables.
