I was just trying to do 50 drops of VG and 50 drops of PG then play with flavors into 5ml bottles.
I think my best play is to do a big mix of all my pg and vg, add my nic to % and store it in one nice brown "brewers" bottle. I can then pour out mils as I need them for mixing. Not using needle tips is a good suggestion as well has warming the mixture up a little bit to get the VG viscous. I have some nice smaller funnels to get it into the bottles. I can "froth" mixes in glass measuring cups then transfer into bottles for steeping and use. I do not want to dilute with water at this point.
Thanks for all the advice. I know there are other threads with mixer's method for sampling, mixing and storing.
If your just doing Test Samples and are using Drops, maybe a Regular Eye Dropper would work better for you?
I like Using a Graduated Cylinder. Because I don't make 5ml Test Batches. DIY is Dirt Cheap. So the Smallest Batch I like to make is 30ml.
