hmm, I like the 60, 20, & 10 ml syringes, and used the needles for wrapping coils, till I got me artistic wire coiling gizmo, so now only do tension wrapped micro coils

I usually just put a finger over the end of the syringe, and pour me liquids up to the desired level, then place it over me mixing vessel and plunge it in. Only use a needle when extracting extracts when needed. Lately will try and adjust me recipe so that am using full 8 ml bottle of flavor extracts, so usually can just pour the bottle in the mix and not have to measure
Course a test batch of juice for me is 100 ml, and make me house select juice batches in 400 or 500 ml quantities. The glass beakers are nice, but kind of thin walled, now use mason glass jars to mix me juice in. Usually leave it in the glass mixing vessel for a couple days, stirring it whenever am in the lab, then pour it off into storage bottles, using 50 ml squeeze bottles for everyday use.
Make sure and get a few glass rods, find them quite handy for stirring up me juices.
Vape long and Prosper.!!!!
