Quick DIY Question.....

There are several good places to get nicotine. I usually get mine from Wizard Labs.

to bring 10 ml of 6mg/ml juice up to 12 mg/ml you'd need to add:

2.5 ml of 36 mg/ml
1.67 ml of 48 mg/ml
1.25 ml of 60 mg/ml
0.68 ml of 100 mg/ml

To bring 10 ml of 6 mg/ml juice up to 18 mg/ml, you'd need:
4 ml of 48 mg/ml
2.8 ml of 60 mg/ml
1.46 mg of 100 mg/ml

Using this spreadsheet I made to get the numbers https://docs.google.com/spreadsheet/lv?key=0Avt3hzdoodlndEpVRzZpNE55V1NHc25HaXlUdVlpeXc&usp=drive_web

 

If you're modifying pre-mixed juice, a higher concentration of nicotine base will always require less volume to be used, as you can see from Spaz's table.

So, a higher concentration of nicotine base (100mg/ml ideal) will have the best chance of altering the flavor as little as possible.

However, it has it's downside. Still using the handy table above, let's say you're bringing your juice up to 12mg/ml. You're more likely to be off by a larger percentage using 100mg/ml, since you need so little: 0.68 ml. In this case, you're flavor is only diluted by less than 7%.

If you were using 60mg/ml strength, and wanted to use 1.25ml, your final concentration wouldn't be off as much if you used 0.02 ml extra, as above. However, your flavor is diluted by about 1.25/10, or 12.5%.

If you're confident in you're measuring abilities, or not as worried about making sure you end up with the absolutely *exact* strength you want, I'd say the higher the concentration of nic, the better.

 

I'd say, the amount of peppery taste added is going to be proportional to the amount of nicotine added (assuming all the nicotine is from the same vendor source). With the different base concentrations of nicotine, you are still adding the same amount of nicotine whether you are adding 2.5 ml of 36 mg/ml or 0.68 ml of 100 mg/ml.

However, as readueler said above, the less volume you add (more concentrated nicotine solution used) the less you dilute your flavors. Adding 2.5 ml is going to dilute your original flavors a lot more than adding 0.68 ml will.

I have not tried nicotine from vaping zone (?) but was just reading a thread where many people say it is the most flavorless nicotine they have found. Though, one person in the thread stated that he found it did not give much of a throat hit, which some people find a desirable effect from their liquids.

Is there any reason not to just buy bottles of your delicious juice in two different strengths?
