These droppers fit 5ml glass doTERRA essential oil bottles as well as some other 5 ml vials. They come assembled for immediate use. Droppers will save you time dispensing and make decanting into sample vials easier.
The droppers save time and oil: they control how much oil you add to a blend or make filling a capsule easy. (To prevent deterioration of the rubber bulb, store the bottle in an upright position and replace the dropper with a regular cap when transporting.)
Contents: 5 pre-assembled dropper caps—including glass pipettes, rubber bulbs, and plastic caps. (Oil bottles not included, for illustration purposes only) Note: This dropper works on vials with an 20-400 neck size.
Squeeze the rubber bulb to draw liquid up into the glass pipette. Gently squeeze the bulb again to release the liquid one drop at a time. Use our cap stickers to identify your samples or bottle contents.
Note: These droppers are designed to be stored/transported in an upright position on top of your essential oil bottle. Please also note that the glass dropper should not touch the bottom of the essential oil bottle, if it does simply push the glass tube up inside the rubber bulb to avoid it coming into contact with the bottle base.
