This pack of 50 replacement pipette droppers is designed for aromatherapy and cosmetics makers who use 50 ml amber glass bottles and prefer a white rubber bulb. The set contains only the dropper cap assembly: extended 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 50 ml glass bottles. The white rubber gives a visually lighter, more modern look to the 50 ml bottle.
What the 50-piece pipette set is for
The 50 ml bottle is typically used for massage oils, body oils, and medium-sized cosmetic serums. The white rubber bulb helps to aesthetically distinguish a 'light' or water-based product line from the 'dark' or oil-based black-bulb line. A pack of 50 provides a season's worth of supply for an active 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 50 ml dropper bottle. The pipette is approximately 105 mm long, reaching the bottom of a 50 ml bottle.
Compatibility with 50 ml bottles
The set is sized specifically for 50 ml amber glass dropper bottles. It fits the standard GL18 neck on 50 ml dropper bottles regardless of supplier. The pipette length matches the internal height of a 50 ml bottle exactly, so the full contents can be drawn up. It also fits smaller (10-30 ml) bottles 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
- Precise dosing of 50 ml massage oils and body oils
- Light, minimalist-aesthetic cosmetic lines in medium-large formats
- Precise dispensing of hydrosols and floral waters from the 50 ml bottle
- 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.
