wholesale 5ml-20ml molded bottle vulcanized moulded bottle moulded bottle vials of sterile powder vial

Our 5ml-20ml vulcanized molded glass vials are designed for storing/transporting sterile powders (antibiotic powders, vaccine lyophilizates, biopharmaceutical bulk powders). They combine structural strength, pharmaceutical-grade safety, and flexible custom packaging to preserve sterility, stability, and efficacy – meeting global pharma/biotech standards.

• 5ml-10ml: Ideal for single-dose powders (lyophilized vaccines, emergency antibiotics) – compact, low-contamination risk during reconstitution.
• 15ml-20ml: Perfect for multi-dose formulations (hospital bulk antibiotics, diagnostic reagents) – ample capacity for repeated access.

Vulcanized molding ensures uniform internal volume for consistent filling.

Made from USP Type I borosilicate glass (pharma sterile packaging standard) via advanced vulcanized molding:

• Superior impact resistance (no microcracks/uneven walls) – safe for fragile powders.
• Chemical inertness: Prevents ion leaching/reactions with powders, maintaining efficacy.
• Sterilization-compatible: Withstands dry heat (180°C) and gamma irradiation without deformation/particle release.
• Ultra-transparent: Enables visual inspection (clumping, discoloration, foreign particles).

• Smooth inner surface: Reduces powder adhesion, ensuring full recovery during reconstitution.
• Standard neck finish: Fits pharmaceutical-grade rubber stoppers (bromobutyl with Teflon) and aluminum caps – airtight/moisture-proof seal.
• Wide mouth (15ml-20ml): Eases bulk powder filling and liquid reconstitution for labs/hospitals.

• Vial customization: Silk-screen/laser engraving (batch numbers, logos; FDA-compliant inks) + color-coded vials/caps (for easy identification).
• Bulk/unit packaging: Sterile HDPE trays (with desiccants in foil bags) for bulk; blister-sealed Tyvek® lids (tamper-evident) for single-dose.
• Custom labels: QR codes (traceability) or regulatory info (compliant with EU/US standards).

Meets/exceeds global standards: USP/EP/JP/Chinese Pharmacopoeia (Type I glass), ISO 15378, cGMP.

Every batch undergoes testing (dimensional accuracy, sterility, seal integrity) – full docs (CoA, MSDS) provided.
