Precision 1.5ml Clear Glass Vials with 13-415 Screw Thread - Professional Storage & Sampling Vials for Essential Oils & Lab Reagents - OEM China Source Factory

Standardized Precision for Sensitive Sample Storage

When your high-value formulations require a more robust sealing surface than standard vials, our 13-415 Thread Glass Vials provide the perfect balance of compact size and secure closure. This specific thread style is favored by R&D Managers for its superior grip and leak-proof performance.

Why Our 13-415 Vials Are the Professional Choice:

• Reliable 13-415 Sealing (For Sourcing Managers): The 13-415 neck finish provides a wider opening and more substantial threading than smaller 9mm vials, making them easier to fill while ensuring a deeper, more secure cap engagement to prevent the evaporation of volatile compounds.

• Pharmaceutical Grade Clarity (For R&D Managers): Manufactured from neutral borosilicate glass (USP Type I), our vials are virtually inert. This ensures your samples—whether they are high-end essential oils or critical diagnostic reagents—remain uncontaminated by alkali leaching or pH shifts.

• Engineered for Durability: Our automated production process ensures uniform wall thickness, allowing these vials to withstand centrifugal forces and rapid temperature changes without cracking.

• Direct Factory Advantage (China): As a dedicated source factory, we provide batch-to-batch consistency that distributors can't guarantee. We offer competitive pricing for bulk orders and complete customization for caps and liners (Septa).

Solving Your Packaging Challenges:

• Zero Leakage: Specifically paired with 13-415 caps to ensure a 100% airtight seal during international transit.

• Easy Handling: The slightly wider 13mm opening reduces spill risk during manual or automated filling.

• Global Compliance: Fully compliant with ISO and medical-grade packaging standards.
