Gore to launch line of plungers for pre-filled syringes


W.L. Gore & Associates, Inc. plans to commercially launch the ImproJectPlunger for pre-filled syringes.

The plunger will be unveiled at a trade show event in Orlando, FL.

Conventional pre-filled syringe systems use silicone to help provide a seal and to act as a lubricant between the barrel and the plunger.

However, there can be problems associated with silicone impacting broader drug stability for some highly complex sensitive drugs.

By eliminating the need for silicone from the barrel and the plunger, the Gore ImproJect Plunger may enable today’s more challenging sensitive biologics to be administered in a pre-filled syringe, a practice that may not have been an option in the past.

“Our approach eliminates the need for silicone in both plunger and glass barrel, while ensuring the functionality and performance of pre-filled syringes,” said Christiane Gumera, Product Specialist, Gore PharmBIO Products.

W. L. Gore & Associates is a global materials science company based in Newark. Gore employs 9,500 Associates and generates annual revenues of $3.5 billion.
