Drop Counts Not 20 per mil

[FreeTimeNow]

Everything I read says 20 drops = 1 mil so tonight I decided to test that as I am starting to try to dial in my flavor percentages. To my surprise I found it took like 40 drops from 1) a 20 mil bottle dropper and 2) a disposable pipette. I took a 5 mil bottle and using a syringe put 1 mil in it and marked with a line around it. Then I emptied it and dropped PG and counted each drop up to the line.
Are people using different droppers to arrive at 20 drops per mil?

Just keep in mind...a drop to you is not a drop to me, or a drop to him or to her. And not everyone uses the same 'dropper'. The best way to measure anything is to use the correct tool.

Probably the best DIY purchase I made was a graduated cylinder from Wizard Lab. I like the glass ones because they are easy to clean up and see the markings. Good luck to you and happy mixing.

There always will be talk and discussion about accuracy in measuring the liquids we use for DIY. To me the most important measurement "goal" is repeatability. Doesn't matter to me if it takes 20, 25, 32, or 50 drops to make a ml. As long as I can get the same volume every time that's all I care about. Once I stopped fretting about whether my ml's were accurate, DIY became much more enjoyable to me.
I have also gravitated to using the more concentrated flavors and measuring in ml's became a pain. I use drops with the understanding that it may not be accurate to a quantitative chemist, but for me it's just dandy. If I do want to make a larger bottle of a juice I'll use an insulin syringe.
This is just my way of approaching mixing. Not saying it's for everyone. YMMV as they say..

Hope everyone has a wonderful Christmas and got all the vaping goodies they wished for!!!

All droppers are not created equal. A 28 ga insulin needle delivers ~ 250 drops/ml. You have to check against a known volume, or, check how many drops of water equal a gram. Still, it will not be uber accurate due to different densities of different liquids. Best to use graduated instruments, or a scale using known densities.

The ejuice Me Up calculator provides a way to set the drops per ml, which helps a little. If you're using different brands that number probably won't be correct for each one but like I said, it still helps a little. I usually use a graduated cylinder for new mixes then covert to drops and syringes for larger mixes when I get the recipe to where I want it.

Happy holidays everyone!

I agree. That's what works for me and has for a long time now
