Syringes with reduced tungsten residues

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.

To reduce tungsten residues in conventionally manufactured syringes, we offer our customers the option of subjecting the syringes to an additional cleaning step in a washing machine after the glass has been formed.

Through the combination of water and ultrasonic bath, our internally developed, multi-stage treatment system thereby reduces not only the tungsten load dramatically by 90% on average , but also brings down the load of glass particles by up to 90 percent.

Gx® Prefillable Glass Needle Syringes

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).

Our range encompasses stainless steel cannulas of the most varied lengths, diameters and bevel types. They ensure intramuscular or subcutaneous injections with minimal pain. The steel quality of the cannulas used corresponds to AISI 304, the sizes to standard DIN 9626.

Cannula properties:

  • Siliconization in the RTF process with Dow Corning® 360
  • Cannula length: ½“ (12.7 mm) and  ⅝“  (15.9 mm)
  • Diameter: 23G, 25G, 26G, 27G, 29G
  • Standard and thin-wall cannulas
  • Bevel: 3 Bevel, 3 Bevel XL, V Bevel®

The needle shield protect the cannula against deformation up to injection, and keeps the cannula sterile until use. Our range encompasses flexible needle shields (FNS) and rigid needle shields (RNS).
