Hoping someone can save me some intense math re 100 mg/dL juice

[SimpleSins]

I just got my package of nic juice in (thanks Levy for amazingly fast shipping). Most of what I got was in 50, but I did get one of the little samplers of 100 mg/mL. I vape at a fairly low nic level, anywhere between 5 and 10. I'm still in the discovery phase so I am not making big batches of anything, so I wondered if anyone knew how much nic a single drop of the 100 mg/mL sampler would add to 5 mL base? As a point of reference, it appears to be the "standard" 3 mL bottle that comes in most DIY kits.

Don't have any math magic for you, but I can tell you what I would do.

I'd put on my face shield and drip into a graduated cylinder. I'd count the drops to reach the 2ml or 3ml mark. Then I'd divide the number of drops by the ml's I measured out so I know how many drops are in a ml of that liquid with that bottle. I'd then pour the cylinder back into the bottle and add a label of how many drops it took to equal a ml. (Example: 29d/ml)

I've gotten completely away from using drops as a measure. I've found there are too many differences between droppers, and then add that some liquids are thicker than others so they drop at a different rate, etc.

I just use syringes..1ml for the smaller stuff like nic juice and flavorings and larger for PG/VG. That way everything is measured perfect w/o worrying about droppers.

I also use syringes. I set up a smallish plastic storage box bottom, lined with paper towels, with every thing that I might need inside (syringes labeled with a sharpie, 100mg/mL e-juice, flavorings, distilled water, PG, and VG). This way I never have to turn away from the work or reach for anything. If anything does get knocked over it is contained in the plastic box, small drops of nic that I might not be able to see are absorbed by the paper towel (rather than my sleeve).

Pipette pump for the win! Sorry, just love my new toy. Word of advice on the pumps, i got both the 2ml pump (handles 1ml & 2ml pipettes) and a 5ml pump (handles up to 5ml pipettes) only to find out that there's no need for the small since the 5 handles 1-5... doh!

Correct me if I'm wrong, but if you:

Add 0.5ml of 100mg/ml liquid to 5ml of juice, you get 50mg of nicotine in 5.5ml of solution or: roughly 9.1mg/ml which is at the high side of your range.
So, maybe 0.4ml would be better for you, as that gives 7.4mg/ml

Unless my math is wrong in which case:

 

[DaDuke]

Ran that through the "easy e-juice calculator" and it says thats about 8.5mg / ml for that formula (.5ml @ 100mg + 5ml @ 0mg = 5.5ml @ 8.34mg)
0.4ml @ 100mg + 5ml @ 0mg = 5.4ml @ 8mg

0.4ml @ 100mg + 5ml @ 0mg = 5.4ml @ 8mg

So I don't make a mistake when I DIY myself later, how does that math work?

0.5ml of 100mg/ml = 50mg of nicotine.

50mg in 5.5ml (5ml base + 0.5ml nic solution added) = 50/5.5 = 9.09

Similar with 0.4: 0.4*100 = 40mg nic / 5.4ml total =7.407

If you like low nic level, it's too much of a hassle to be accurate playing with 100 mg. I'd bulk downmix it, to give something easier to work with.
Pour the 3 ml of 100 mg into a 10 or 15 ml bottle, add 6 ml of PG and you would have 9 ml of 33 mg concentration. The 33 is then easy to use to make 16.5 mg (1 part other stuff to 1 part nic liquid), or 11 mg (2 parts other stuff to 1 part nic liquid), or 8.25 mg (3 parts of other stuff).
Going to 33 also means you only have to deal with the 100 mg that one time.

Just a thought...

0.5ml of 100mg/ml = 50mg of nicotine.

50mg in 5.5ml (5ml base + 0.5ml nic solution added) = 50/5.5 = 9.09

Similar with 0.4: 0.4*100 = 40mg nic / 5.4ml total =7.407

Your math is right to get that total without flavoring added.

If you want to get things right use Scubabatdan's e-juice calculator. It works very well.

Go down to the OP's sig, the link to it is underneath.

That's how i would have calced it on paper but i just ran it through that juce calulator and thats what it said. I only calced it as o flav pg and 100mg nic in the appropriate amounts. I didn't add anything for flav and then triple checked the numbers. Dunno...
