Simple, cheap, and works even with thick fluid like vegetable glycerine. Use them and throw them away.

First one broke at the seal but the other 3 have been used multiple times.

These Pipette Dropprts work very well for exact drop measurements for measuring essential oils recipes and other liquid oils.

Cheap! Plastic cracks on the seam!

Pretty basic, but they were useful. I made some essential oils blends, and they did their job.

These droppers are advertised as being disposable; I've used the same two almost everyday this week (as I've been learning how to use essential oils, and how to blend my own mixtures). I soak them in hot soap water, wash, rinse, allow to air dry and they're read to go again. They aren't a real thick plastic, so if I used them and had to throw it away, I wouldn't have to feel guilty about it either. When I wear these out, I'll definitely reorder.

We had some cinnamon oil in an eye-dropper bottle that seemed to have eaten away at the rubber part of the eye-dropper, almost completely disintegrating it. We got to thinking that maybe the cinnamon had leached some chemicals out of the rubber, too. These pipets are a great idea as an alternative. We can extract a small amount of cinnamon (or clove oil) as needed, and then clean the pipet afterwards. Just to be safe, we've decided to go this route from now on.
