Looks like Liquid Barn doesn't sell funnels or pipettes, so I will grab some of those when I make my order at Bull City later. Is there a funnel size you would recommend?
I tried funnels and I wouldn't recommend them. Especially with 80% VG nic. It's very thick. I remember filling up a funnel and sitting there holding the funnel until my fingers cramped up waiting for the VG to drip through it. I picked up several sizes of funnel including a tiny glass one, think they are all in a box in the attic now. Same with syringes. Even without a needle it was slow and messy to suck the stuff up and push it into the mixing bottle.
Now I just pour the nic from the bottle into a graduated cylinder. If you go slowly that works pretty well. There might be a better way but I didn't have any luck with funnels or syringes. Cylinders aren't super accurate but they are cheap and easy to use. Never tried pipettes though.
Another option is to stand the nic bottle in warm water for a while. When it warms up it gets thinner and you might have better luck running it through a funnel.
