The 30 ml cobalt blue glass dropper bottles combined with black pipette droppers are ideal for those who also value precise, drop-by-drop dispensing. The glass pipette and the black rubber bulb release exactly as much liquid as needed — no more, no less. This 110-piece pack is intended for essential oil creators, aromatherapy artisans, and cosmetic formulator small business owners.
What is included in the 110-piece pack
110 cobalt blue glass dropper bottles, each with a nominal 30 ml fill capacity and a matching black pipette dropper. The height of one bottle is approximately 85 mm and the diameter is 35 mm. The pipette length is around 70 mm, so it easily reaches the bottom of the bottle. The total gross weight of the pack is around 6.05 kg, and an empty bottle with pipette weighs approximately 60 g together.
Cobalt blue glass and the benefit of light filtering
Cobalt blue glass absorbs not only the UV range but also part of the shorter visible wavelengths — particularly blue and green light. This extended protection provides longer shelf life for preparations that are sensitive to light. The glass is fully chemically inert: it adds no off-flavour or odour to the contents and contains no BPA or plasticisers.
Advantages of the black pipette dropper
The pipette dropper is made of glass with a black plastic top and a black rubber bulb. The glass pipette does not contaminate the liquid and is easy to clean. The rubber bulb draws up liquid when slightly compressed and releases it drop by drop when pressure is reduced. This design allows precise, controlled dispensing — particularly important for essential oil blends where even a 1-2 drop variation can influence the desired effect. The pipette can be replaced on the bottle thanks to its standard thread.
Areas of use
- Precise drop-by-drop dispensing of essential oil blends

- Dispensing botanical tinctures, hydrosols, and flower essences
- DIY beauty products and own-brand creation for small business owners
Cleaning and reuse
The bottle and the glass pipette can be rinsed in warm soapy water. The rubber bulb requires particular attention: strongly scented or solvent-based liquids (such as alcohol-based perfumes or sulphur-containing essential oils) can damage it over time, so periodic replacement is recommended. For stubborn scent residue, pure ethyl alcohol (70%) is recommended, but only leave the rubber components in alcohol briefly. Avoid dishwasher use.
