The CY-942 to CY-946 Series represents our professional-grade Amber Boston Round Glass Bottles, available in globally recognized capacities: 15ml, 30ml, 60ml, 120ml, and 250ml. Characterized by its iconic rounded shoulders and robust cylindrical base, this series is crafted from high-purity solid Amber glass, providing superior UV-shielding properties to protect light-sensitive reagents, essential oils, and pharmaceutical compounds from photo-degradation. With a reinforced weight range from 31.9g to 185.5g, these bottles offer the exceptional chemical resistance and structural integrity required for high-speed automated filling. The precision-engineered Screw Neck finish (GPI/GCMI standard) ensures seamless integration with a variety of professional closures, including poly-cone caps, glass pipettes, and lotion pumps.
Lightweight yet durable (31.9g), it is designed for B2B clients seeking reliable packaging solutions for cosmetics, personal care products, and small-scale liquid production.

• Closure Torque Specification: To ensure a 100% airtight seal, ensure that automated capping machinery is calibrated to the specific GPI/GCMI thread profile of each model (15ml-250ml).
• Thermal Shock Management: These bottles are fully annealed; however, maintain a temperature differential of under 38°C during industrial washing or hot-filling to prevent stress fractures.
• Chemical Compatibility: While Amber glass is virtually unreactive, we recommend a compatibility test for high-concentration volatile solvents or extremely alkaline solutions over long-term storage.
• UV Protection Efficacy: Amber glass offers the highest light protection; nonetheless, store bulk pallets in a cool, shaded environment to maximize the shelf life of the contents.
• Hygiene Standards: Our bottles are produced in high-hygiene facilities; we recommend a standard deionized air rinse or water flush prior to the first aseptic filling.

• Global Laboratory & Chemical Supply: The primary choice for B2B distributors providing standardized, non-reactive glassware for chemical reagents, diagnostic liquids, and specialized tinctures.
• Premium Apothecary & Wellness Branding: A strategic solution for brands launching high-potency Vitamin C serums, facial oils, and botanical extracts where "Amber Glass" is the industry signal for premium quality and stability.
• B2B Industrial Clean-Label Packaging: Ideal for concentrated fragrance oils and fine-chemical manufacturers looking for durable, sustainable glass packaging that emphasizes product purity.
• Horeca & Executive Grooming Kits: Perfectly suited for luxury hotel amenities or professional barber-shop product lines (e.g., beard oils, hair tonics) requiring a vintage-style, heavy-duty glass vessel.
• Sustainable Bulk-Refill Logistics: Designed for international B2B partners implementing circular economy programs; the reinforced 31.9g-185.5g build supports multiple reuse and sterilization cycles without degrading.
