Choosing the right dropper is critical to ensuring your product’s shelf life and user experience. Our 18/400 Glass Dropper Assembly is engineered for precision, durability, and professional aesthetics, making it the preferred choice for Sourcing Managers and R&D Professionals in the skincare and wellness industries.
Why Our Dropper Stands Out in the Global Market:
Medical-Grade Precision (For R&D Managers): Each glass pipette is crafted for consistent drop size, ensuring accurate dosing for high-potency serums, essential oils, and pharmaceutical liquids. The rubber bulb provides excellent suction power without leakage.
Universal Compatibility (For Sourcing Managers): The standard 18/400 neck finish is compatible with a wide range of Boston Round and Euro glass bottles. We offer custom pipette lengths to fit your specific bottle height, reducing the risk of bottom-residue waste.
Premium Build Quality: The ribbed plastic cap provides a non-slip grip and a professional look. The glass is chemically inert, ensuring that your formula remains pure and uncontaminated over time.
Cost-Efficient Source Factory (From China): By working directly with our factory, you bypass distributors, reducing costs by 20-30% while maintaining high-end manufacturing standards.
Solving Your Packaging Pain Points:
Say Goodbye to Leaks: Our precision threading ensures a 100% airtight seal, preventing oxidation and spills during transit.
Customizable Aesthetics: Available in various bulb materials (Silicone/NBR) and cap colors to match your brand identity.
Low MOQ & Fast Sampling: We understand the need for speed in product development.
