This pack of 50 replacement pipette droppers is designed for aromatherapy and cosmetics makers who use 30 ml amber glass bottles and prefer a white rubber bulb. The set contains only the dropper cap assembly: glass pipette plus white rubber bulb plus threaded sealing rim. The bottle itself is not included, so you are free to combine these with your existing 30 ml glass bottles. The white rubber gives a visually lighter, more modern look to the 30 ml bottle.
What the 50-piece pipette set is for
The 30 ml format is the most popular size for custom essential oil blends, facial serums, and more concentrated body oils. The white rubber bulb aesthetically separates a 'white line' (for example water-based or hydrosol-containing preparations) from the black-bulb oil line. A pack of 50 is a season's worth of supply for an actively working small workshop.
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 white rubber bulb is as flexible as the black one; in pigment terms it is generally coloured with titanium dioxide, which is biologically inert. The threaded sealing rim is plastic and fits the standard GL18 neck of a 30 ml dropper bottle. The pipette is approximately 95 mm long, reaching the bottom of a 30 ml bottle.
Compatibility with 30 ml bottles
The set is sized specifically for 30 ml amber glass dropper bottles. It fits the standard GL18 neck on 30 ml dropper bottles regardless of supplier. The pipette length is optimal to reach the bottom of a 30 ml bottle, allowing the full contents to be drawn up. It also fits smaller bottles (10-20 ml) with a GL18 neck, but is longer than necessary.
Use cases
- Colour-coded product line: white bulb for water-based, black for oil-based preparations
- Light, minimalist-aesthetic cosmetic lines in 30 ml format
- Precise dosing of facial serums and concentrated skin oils
- Building your own bottle-and-cap combinations on aesthetic grounds
- Quick replacement of broken, cracked, or discoloured pipettes
Cleaning and storage
After use, wash the pipette with warm water and a mild soap, then rinse with alcohol for complete deodorisation. The white rubber bulb shows pigment residue from scented preparations particularly well, so a thorough rinse is worthwhile after cleaning. Store unused pipettes in their original packaging, in a dark place, so the white colour does not yellow.
