Product Description

The 5mm Breathable Moisture-Control Molecular Sieve Vial Seal is a breakthrough in precision packaging for moisture-sensitive pharmaceuticals. Engineered with a composite polymer/molecular sieve matrix, it actively maintains critical humidity levels (20-40% RH) while allowing controlled gas exchange.

Engineered for precision protection, our 5mm molecular sieve vial seal combines advanced moisture control with optimal breathability to safeguard sensitive pharmaceuticals. The innovative triple-layer structure features:  

Smart Humidity Regulation	Molecular sieve core maintains 25-45% RH regardless of external conditions
Controlled Gas Exchange	Micro-engineered pores (0.2μm) allow necessary O2/CO2transfer while blocking contaminants
Instant Moisture Alert	Color-changing indicator (blue→pink) visually signals when RH exceeds 50%

 

Perfect Seal Integrity	Zero leakage at 3.5 bar pressure (ISO 8362-4 compliant)
Material Safety	USP Class VI certified elastomers with <0.05% extractables
Process Compatibility - Validated for	•Automated filling lines (up to 500 vials/minute)      • Cryogenic storage (-196°C LN2compatible)      • All major sterilization methods

 

Critical Performance Features:  

 

5mm precision fit	Leak-proof sealing for micro-volume vials
Self-regulating	Maintains 30-50% RH regardless of external conditions
Visual moisture indicator	Color changes from blue to pink at 60% RH
Sterilization-ready	Validated for ethylene oxide and gamma irradiation

Ideal for:  
• Lyophilized biologics requiring strict humidity control  
• Hygroscopic API storage  
• Diagnostic reagent preservation  
• Long-term stability studies
