Review on Graduated Thick Glass Dropper Pipettes by Chad Mills

The pipettes were well packaged and appear to be well constructed. I bought these to get accurate measurements for homemade perfumes and thought they would be more accurate than drops from essential oil dropper bottles. These are my first pipettes so I'm learning as I go, but I'm having a really hard time matching oils to gauge lines - air bubbles completely change the reading and I seem to be measuring inaccurately even holding air bubbles. I've spent a lot of time filling and emptying them and I don't know if I've gotten any better on my own. I plan to look them up on youtube so my advice is if you know how to do it or have a lot of patience to get the technique right these are very well made pipettes. is that one of the tips of the pipette is made of latex. I'm allergic to latex and had to throw it away. However, after an hour of searching Amazon, this is one of the few silicone drip kits. In most sets, the top is made entirely of latex. So in my opinion that's something else that this set really needs. If all pipettes were silicone/non-latex I would give 5 stars.
