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

Can't tell how accurate they are; I don't work in a lab, but Bomex seems to make pretty accurate instruments for an amateur chemist like me. I've paired them with a serological pipette controller (check out the Levo model for about $25) and it's like magic. I plan to ditch the included lightbulbs soon, but the eyedropper cleaning brushes are great. With the pipette control, I can draw up precise amounts of liquid and dose at will, then clean and reuse these glass pipettes. They snap at the tips if you're not careful, or break entirely if you're careless; I just bought a second set to have backups. At $15 with shipping, this set is worth every penny. I hope this helps you.
