New choice for leak-proof and shatter-proof dropper bottles
In laboratories and cosmetic production, traditional glass dropper bottles are often fragile, poorly sealed, and insufficiently protected from light, resulting in reagent waste, sample contamination, and storage risks. Are you troubled by frequent replacement of dropper bottles, uncontrolled evaporation of liquids, or failure of photosensitive ingredients due to packaging defects? 16mm Glass Dropper Bottles, designed for harsh scenarios, end pain points with innovative solutions!
Solutions and core values
This product uses high borosilicate glass (temperature resistance > 150°C), with precision droppers and silicone sealing rings, to achieve zero leakage + impact resistance dual protection. The bottle diameter is strictly controlled at 16mm±0.5mm, suitable for standard brackets and portable devices; amber materials (such as 3ml amber glass vials) can block 99% of ultraviolet rays to ensure the stability of photosensitive substances 26. Actual measurements show that there is no cracking at a temperature difference of -20℃ to 120℃, and there is no leakage after repeated squeezing of the dropper for 10,000 times, which greatly reduces losses and safety risks.
Global application scenarios
Scientific research: accurate titration of corrosive reagents (such as acids and organic solvents), replacing low-end plastic sub-bottles25;
Cosmetics: storage of photosensitive active ingredients such as essential oils and VC essences (Amber glass bottle with pink cap provides brand customization options)69;
Medical sub-packaging: 3ml amber glass vials independently packaged oral liquids and vaccine excipients;
Wholesale supply: support small glass vials wholesale batch customization to meet the centralized procurement of pharmaceutical factories and colleges6.
Product features and tips
Featured innovation:
Silicone protective layer: the bottle body is wrapped with 1.5mm shock-absorbing silicone (optional matte colors such as dark blue and dark green), resistant to 1.5-meter drop impact, anti-slip and anti-collision39;
Precision drop control: the inner diameter of the drip nozzle is 0.5mm±0.02mm, the drop error is <3%, and it is suitable for trace addition needs28;
Light-proof + customization: amber glass blocks ultraviolet rays, supports flexible selection of bottle caps (such as pink custom caps) and pipette tips (straight/bent)6.
Tips for use:
Compatibility test: When containing strong alkaline solutions, PFA valve stem dropper (pH 14 resistance) is preferred5;
Seal maintenance: Regularly replace the silicone ring (recommended cycle is 6 months) to prevent aging and leakage;
Store in dark places: For light-sensitive ingredients (such as silver nitrate), choose dark amber bottles with a light protection rate of > 99%6.
Choose 16mm dropper bottles, which means choosing precision, safety and cost control:
Say goodbye to volatile losses in the laboratory,
Reduce the defective rate of the production line,
Small batch customization (small glass vials wholesale) helps start-up brands to reduce investment.
