Data Sheets,
GORE® IMPROJECT® Plungers eliminate the need for silicone as a lubricant in pre-filled syringes. Used with bare-glass (non-siliconized) barrels, these silicone-free plungers provide consistent delivery performance over time, and can protect complex or sensitive biologics from silicone-induced aggregation and particulation.
Overview
Eliminate silicone in both barrel and plunger to protect sensitive biologics in glass pre-filled syringes (PFS)
Today’s complex biologics, such as monoclonal antibodies and conjugate vaccines, can be vulnerable to silicone-induced protein aggregation, particle formation and drug product precipitation. In addition, over time, silicone migration can impact consistency of delivery, as it may change break loose/glide force (BLGF) and injection time. As a result, many biopharmaceutical manufacturers are actively seeking ways to address issues related to silicone sensitivity.
Now, GORE IMPROJECT Plungers Offer A New Solution
For the first time, GORE IMPROJECT Plungers enable glass syringe manufacturers to completely eliminate silicone from both plunger and barrel in their PFS.
New GORE IMPROJECT Plungers for pre-filled syringes protect complex and sensitive biologics from silicone-induced protein aggregation and particulation. They do so by completely eliminating the need for silicone in both the syringe plunger and the glass barrel.
- The syringe plunger material is completely silicone-free: Silicone is not a raw material and is not used in the manufacture of the plungers.
- Designed for use in bare-glass (non-siliconized) barrels, these syringe plungers provide excellent container closure integrity (CCI) and maintain consistent drug delivery time in two-year and accelerated aging tests.
Exceptionally Low Particles
Gore's low-particulation plungers effectively protect many of the more complex biologics that are silicone-sensitive. In addition to meeting USP <788> sub-visible particles standards, testing demonstrates that GORE IMPROJECT Plungers provide:
- Orders of magnitude reduction in sub-visible particles, compared to siliconized syringes.
- Excellent biocompatibility: 21 CFR Part 4 and ISO 10993-1.
- No significant extractable compounds, due to our plunger’s proprietary PTFE-based fluoropolymer barrier.
For results of our Particulate and Aging tests, see our Data Sheet.
Functional Performance
The only plunger that enables low particulates and consistent delivery over time in bare (silicone-free) glass barrels.
Due to its proprietary plunger design and fluoropolymer barrier, the GORE IMPROJECT Plunger ensures:
- CCI (Container Closure Integrity) - testing of pre-filled syringes demonstrates highly effective protection against drug loss, leakage and microbial ingress.
- Consistent injection times including auto-injector applications – no auto-injector stalls or auto-injector fails, even after accelerated aging conditions.
- Low extractables and leachables: No significant extractable compounds.
A New Option for Drug Delivery
GORE IMPROJECT Plungers provide the only option for a silicone-free PFS (plunger with glass barrel), which protects sensitive biologics from potential interactions with silicone.

Are you exploring new types of pre-filled syringes for intravitreal injections?
Gore is focused on addressing issues of concern with PFS for retina injections, including:
- The need to significantly reduce particle counts, in compliance with USP <789>
- Silicone-linked sequelae including silicone oil-induced floaters4,5 and silicone-induced inflammation6,7
- Increasing Inter-Ocular Pressure (IOP) with repeated injections over time1,2,3

Gore meistert schwierige biopharmazeutische Herausforderung
Veröffentlicht: Juli 30, 2019
Wem schon mal ein neues Handy runtergefallen und das Display dabei kaputtgegangen ist, kennt das Gefühl, etwas Wertvolles zu verlieren. Um so schlimmer ist es, wenn es um etwas geht, das Tausende oder sogar Millionen Euro wert ist und Menschenleben retten könnte. Und genau so ergeht es Arzneimittelherstellern, wenn ein Einwegbeutel mit empfindlichen biologischen Substanzen nicht hält. Eine neue Lösung von Gore beschäftigt sich mit diesem Problem.
A partnership between Gore and the biotech company ViaCyte could open new possibilities for people with diabetes.
In Zukunft könnte Krebs im fortgeschrittenen Stadium bald als chronische Krankheit gelten anstatt lebensbedrohlich zu sein. Schwere Autoimmunerkrankungen könnten bereits an ihrem Ursprung bekämpft werden. Und Patienten mit fortschreitenden neurologischen Erkrankungen könnten Hoffnung auf ein langes gesundes Leben schöpfen.
NOT INTENDED FOR USE in medical device or food contact applications or with radiation sterilization.
