13mm & 20mm Butyl Rubber Stopper with Self-Healing Injection Port – Medical-Grade Solid Seal for Glass Vials
Premium Self-Healing Rubber Stopper with Dual-Lip Design – Ideal for Injectables, Vaccines, and Biologics в Type I Borosilicate Glass Vials
Сайт 13mm and 20mm Butyl Rubber Stopper with Self-Healing Injection Port с сайта PharGlass is engineered to deliver superior seal integrity, low extractables, и reliable resealing performance after needle penetration. Designed specifically for use in pharmaceutical glass vials, this medical-grade rubber closure features a dual-lip (U-shaped) structure that ensures tight sealing against moisture, oxygen, and microbial ingress — making it ideal for sterile injectable drugs, mRNA vaccines, и lyophilized biologics.
This solid seal stopper is widely used in multi-dose vials where repeated access via syringe is required. Its self-healing property allows the rubber to close automatically after needle withdrawal, minimizing product leakage and contamination risk — a critical feature supported by USP и EP 3.1.9 стандарты.
Manufactured under ISO 9001:2015 и GMP-compliant conditions in Henan, China, every stopper undergoes rigorous quality control, including extractables testing, visual inspection, и bioburden analysis, ensuring full compliance with global pharmaceutical regulations.

Why This Design Matters: The Science Behind the Dual-Lip Structure
Сайт U-shaped (or dual-lip) design of this rubber stopper is not just aesthetic — it’s a functional innovation that improves performance in several key areas:
🔹 Enhanced Puncture Resistance: The two raised lips distribute needle pressure evenly, reducing deformation and improving durability during multiple withdrawals.
🔹 Improved Re-Sealability: After needle withdrawal, the elastic rubber returns to its original shape, forming a tight seal without gaps.
🔹 Reduced Risk of Product Loss: Critical for high-cost biologics и vaccines, where even minor leakage can lead to waste or contamination.
According to a study published in Журнал фармацевтических наук (2021), U-shaped stoppers reduce leakage rates by up to 40% compared to flat-faced designs in multi-dose applications.
Material Comparison: Which Rubber Is Right for Your Formulation?
| Rubber Type | Best For | Key Advantages |
|---|---|---|
| Butyl Rubber | General injectables, liquid formulations | Cost-effective, good elasticity, low gas permeability |
| Bromobutyl Rubber | Вакцины, biologics, multi-dose vials | Enhanced chemical resistance, better adhesion to aluminum seals |
| Chlorobutyl Rubber | Лиофилизированные (сублимированные) продукты | Superior барьер от влаги, lowest extractables profile |
Примечание: Для сублимированный (лиофилизированный) продукты, мы рекомендуем хлорбутилкаучук due to its excellent moisture barrier properties и low extractables, as confirmed by studies in European Journal of Pharmaceutics.
