This pack of 50 replacement pipette droppers is designed for aromatherapy and cosmetics makers who use 20 ml amber glass dropper bottles and need spare or replacement pipettes available. The set contains only the dropper cap assembly: glass pipette plus black rubber bulb plus threaded sealing rim. The bottle itself is not included, so you are free to combine these with your existing 20 ml glass bottles.
What the 50-piece pipette set is for
The 20 ml format is a favoured size for compact facial serums, concentrated skin oils, and scented blends: small enough to fit in a bag, large enough to last several weeks. A 50-pack of spare pipettes provides a full season of supply for an active small workshop, while allowing a dedicated pipette per blend.
Material and construction
The pipette is made of glass, which is chemically inert: it does not react with essential oils, hydrosols, or alcohol-based tinctures, and adds no off-flavour or odour to the contents. The black rubber bulb is flexible, easy to squeeze, and releases the drop predictably. The threaded sealing rim is plastic and fits the standard GL18 neck of a 20 ml dropper bottle. The pipette is approximately 85 mm long.
Compatibility with 20 ml bottles
The set is sized specifically for 20 ml amber glass dropper bottles. It fits the standard GL18 neck on 20 ml dropper bottles regardless of supplier. It will also fit smaller (10 ml) bottles with a GL18 neck, but the pipette is somewhat longer than required. For 30 ml it barely reaches the bottom, so for 30 ml we recommend the longer variant.
Use cases
- Quick replacement of broken, cracked, or discoloured pipettes
- Dedicated pipettes per aromatherapy blend to avoid cross-contamination
- Precise dosing of compact facial serums and concentrated skin oils
- Building your own bottle-and-cap combinations by selecting the dropper type
- Travel-format essential oil blends and perfume bases
Cleaning and storage
After use, wash the pipette with warm water and a mild soap, then rinse with alcohol for complete deodorisation. Do not leave the rubber bulb soaking in essential oils after cleaning, as it will soften over time. Store unused pipettes in their original packaging, in a dry place protected from direct sunlight.
