13mm, 15mm & 20mm Butyl Rubber Stopper for Lyophilization – Premium Freeze-Dried Product Closure with Low Extractables
Medical-Grade Lyophilization Closures Designed for Biologics, Vaccines, and High-Purity Pharmaceuticals in Type I Borosilicate Glass Vials
The 13mm, 15mm, and 20mm Butyl Rubber Stopper for Lyophilization from PharGlass is engineered specifically for freeze-dried (lyophilized) pharmaceuticals, offering superior moisture barrier performance, low extractables, e excellent resealability after vial sealing. These pharmaceutical lyophilization closures are ideal for medicamentos biológicos, mRNA vaccines, monoclonal antibodies (mAbs), e sterile powder formulations that require long-term stability under controlled humidity conditions.
Unlike standard rubber stoppers, our lyophilization-grade butyl rubber stoppers are manufactured using high-purity raw materials and undergo rigorous extractables testing to ensure they meet the stringent requirements of USP <661>, EP 3.1.9, e FDA 21 CFR 177.1520 standards.
Manufactured under ISO 9001:2015 e GMP-compliant conditions in Henan, China, every stopper is tested for moisture permeability, visual defects, e bioburden control — ensuring consistent quality and regulatory compliance for global markets.

Why Chlorobutyl Rubber Is the Gold Standard for Freeze-Dried Products
For lyophilized (freeze-dried) pharmaceuticals, the choice of rubber material is critical. Here’s why chlorobutyl rubber is preferred over standard butyl:
🔹 Superior Moisture Barrier: Chlorobutyl reduces water vapor transmission by up to 30% compared to butyl rubber (Source: Jornal de Ciências Farmacêuticas, 2022).
🔹 Lower Extractables Profile: Essential for sensitive biologics where even trace impurities can affect efficacy.
🔹 Better Chemical Resistance: Resists degradation from residual solvents and excipients used in formulation.
🔹 Enhanced Seal Integrity: Maintains tight closure under vacuum conditions during the lyophilization cycle.
According to the European Pharmacopoeia (EP 3.1.9), halogenated butyl rubbers (e.g., chlorobutyl) are recommended for high-purity biologics due to their low leachables e high chemical inertness.
