Eliminate silicone in both barrel and plunger to protect sensitive biologics in glass pre-filled syringes (PFS)

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 and particle formation. In addition, over time, silicone migration can impact consistency of delivery, as it may change break loose and glide force (BLGF) and injection time. As a result, many biopharmaceutical manufacturers are actively seeking ways to address these silicone-related issues.

Now, GORE™ ImproJect™ Plungers Offer A New Solution

Caption

For the first time, GORE™ ImproJect™ Plungers enable 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 plunger and the glass barrel.

  • The plungers are silicone-free: Silicone is not a raw material and is not used in the manufacture of the plungers.
  • The plungers, designed for use in bare-glass (non-siliconized) barrels, provide excellent container closure integrity (CCI) and maintain consistent injection performance over time.
Exceptionally Low Particles

GORE™ ImproJect™ Plungers effectively protect many of the more complex biologics that are silicone-sensitive. 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.
Functional Performance

ImproJect Syringe Plungers

The only plunger that enables low particulates and consistent delivery over time in bare glass (non-siliconized) barrels.

Due to its proprietary plunger design and fluoropolymer barrier, the GORE™ ImproJect ™ Plunger ensures:

  • Excellent CCI, to protect against drug loss, leakage and microbial ingress.
  • Consistent delivery including auto-injector applications – even after accelerated aging conditions.
  • No significant extractable compounds.
