Enhanced Container Closure Integrity by Pharglass | Dual-Stopper Design for Reconstitution & Long-Term Stability
Pharglass double-stoppered lyophilization vials are engineered for the most demanding freeze-dried therapeutics—where container closure integrity (CCI), reconstitution reliability, et long-term stability are non-negotiable. Made from USP Type I neutral borosilicate glass, these vials feature a dual-stopper system: an inner stopper that seals the lyophilized cake during storage, and an outer stopper that maintains sterility and enables safe, controlled reconstitution with diluent.
This innovative design is ideal for:
- mRNA-LNP vaccines requiring strict moisture control
- High-potency biologics (e.g., monoclonal antibodies, enzymes)
- Two-chamber reconstitution systems without complex devices
- Clinical trial materials needing multi-step dosing or dilution
Conforme à USP, EP 3.2.1, ISO 8362-1, et YBB standards, Pharglass double-stoppered vials deliver superior protection against moisture ingress, oxygen permeation, and microbial contamination—critical for maintaining potency in lyophilized products with low residual moisture specifications (<1%).

Why Choose Double-Stoppered Vials Over Single-Stopper?
Traditional single-stopper vials require needle puncture for reconstitution—introducing risks of:
- Particulate generation from rubber coring
- Moisture ingress after first use (in multi-dose scenarios)
- Perte de stérilité during manual diluent transfer
Le dual-stopper design eliminates these issues:
- Diluent is pre-loaded in the upper chamber (or added aseptically)
- Reconstitution occurs in a closed system—simply push the outer stopper to mix
- Aucune entrée d'aiguille n'est nécessaire—preserving sterility and reducing operator error
This makes double-stoppered vials a smart choice for point-of-care use, emergency medicine, et resource-limited settings.
