Functional advantages
High precision subpackage: 1ml scale precision ± 0.03ml, suitable for 0.5-1ml perfume trial filling.
Material safety: 3.3 borosilicate glass, certified for alkali resistance A2 level and water resistance HGB3 level (GB/T 12805-2011).
Anti cross contamination: Independent sterile packaging (EO sterilization), in compliance with ISO 22716 microbiological control standards.
Application scenarios
Perfume trial production: 5ml droppers are divided into 2ml samples, and the volatilization loss rate is only 0.2%/month after the screw cap is sealed.
Preservation of perfumer's works: Dark brown glass version (light transmittance<15%) protects photosensitive spices from UV degradation.
Alcohol solution management: Supports the packaging of perfume concentrate with ethanol concentration below 70%, without the risk of glass erosion (tested alcohol compatibility).
