Review on 🔬 High-Quality 20cm (7.8-inch) Graduated Dropper Pipettes for Precise Pipetting by Justin Miller

I bought these for measuring concentrated liquids such as plant vitamins and pesticides. They are much easier to use than measuring spoons. With a whole set, I can dedicate a dropper to a specific liquid to avoid cross-contamination. It was difficult to install the bulbs on the glass, but this is probably necessary for a good fit. I'm not complaining, but if you have weak arm strength I would offer assembly help. I would recommend the manufacturer to wrap each piece of glass in paper. Also include instructions to indicate which bulbs go with which pieces of glass. Otherwise this is a good set.
