Gerresheimer is expanding its range of pre-fillable polymer syringes to include a new product: the Gx RTF® ClearJect® polymer needle syringe, 2.25 ml. Like the 1.0 ml syringe, this syringe will be produced in Pfreimd, Germany.

The material used for the syringe is a high performance polymer called COP (cyclic olefin polymer). It is suitable for use as primary packaging for sophisticated medications, especially for sensitive, biologicals, biosimilars, and biobetters. The product was developed in close cooperation between two Gerresheimer locations in order to create synergy between the syringe experts in Bünde and the plastic experts in Wackersdorf, Germany.

The Gx RTF ClearJect COP SIN of Gerresheimer Bünde GmbH is now available in the sizes 1.0 ml long and 2.25 ml. The design is inspired by ISO 11040-6 and registered. The syringe is equipped with a 27-gauge, 1/2-inch (12.7 mm), thin-walled stainless-steel needle with three bevels.

Low interaction potential of the syringe with the medication

COP does not release tungsten metal ions into the medication solution as glass syringes can, which is a major concern for some. Since the entire syringe, including the insert-molded needle, is produced in a single step, the product, hence becomes free of tungsten and adhesives.The material has a high pH tolerance and the pH value does not change while in storage. The oxygen permeation rate is low in comparison to other plastics, and the values for extractables and leachables are low.

Safety and reliable functionality for the end user

Another important argument in favor of the Gx RTF ClearJect needle syringe is its end-user safety. COP is particularly break-resistant, making it suitable for packaging aggressive or toxic materials. The syringes are siliconized with a precisely controlled quantity of the highly viscous Dow Corning 360 MD (12,500 cST) silicone oil, in order to ensure reliable syringe functionality with low breakaway and sliding forces with the lowest possible particle load.

Precision and flexible design

Production in the injection molding process ensures precise dimensions. The dead volume in the syringe is also minimized, reducing overall waste of the costly drugs. The material enables a broad range of design options, which make it ideal for customer specific-requirements. The syringes are also engineered for use in autoinjectors thanks to their robustness and precision.

Economic efficiency through standard components

This syringe system, like the 1.0 ml syringe, is economical thanks to the fact that the innovative COP syringe body is designed to use commercially available standard components throughout. This starts with the use of standard cannulas and continues with the piston rods, piston plungers, backstops and closure systems used.
