For serums, oils, and tinctures, the dropper is the primary user interface. Thousand Peak Glass manufactures high-precision Glass Dropper Assemblies that combine aesthetic elegance with chemical reliability. We eliminate the common industry plague of "swollen bulbs" by strictly matching the rubber material to your formula's solvent base. From standard DIN 18 essential oil droppers to luxury Push-Button systems, we offer a leakage-free guarantee for every assembly we ship.
Silicone: The standard for skincare. High clarity, soft touch, and excellent resistance to heat and aging. Ideal for water-based or alcohol-free serums.
NBR (Nitrile): Mandatory for oil-based formulas (Essential oils, Face oils). Unlike silicone, NBR resists oil permeation and swelling, preventing the cap from popping loose over time.
TPE/TPR: A recyclable option offering a balance of cost and performance.
Butyl: Engineered for extreme chemical resistance and low gas permeability. The preferred choice for aggressive solvents, strong acids, or pharmaceutical-grade active ingredients where maximum barrier protection is required.
