Someone asked this in a PM and I thought I would respond here in case anyone else is interested.
Had a couple of questions for you about nicotine long term storage. Have you looked at the Armor line of packaging by Nude Nic? Glass bottle, argon purging, luer lock nic access system, and their latest idea of adding ascorbic acid. Just wanted to get your opinion on whether any or all these things might help with the long term storage of nic.
Yes, I think the V2 (luerlok) packaging helps. However, I dont think it even remotely justifies the premium in cost. If you buy glass boston rounds and fill them to just where the narrow neck starts, there is not not enough oxygen trapped in the bottle to do much, even if every bit of the trapped oxygen gets oxidized (unlikely). My habit is to use the smallest bottles that I consider reasonable. The biggest enemy is the introduction of MORE oxygen, not so much what is trapped in the bottle assuming the bottle is full. Plastic can allow more oxygen to enter, thats why we use glass. Opening the bottle is the biggest introduction of oxygen, which is the reason why the NN V2 helps, it prevents MORE oxygen from entering when you use some. If you use small bottles that dont require a lot reopening then you have no need for V2 packaging. "For me" the V2 packaging is certainly convenient, but I can get good nic and a bunch of empty bottles for half of NN's price.
This is a quote from
Kurt, who holds a PhD in Chemistry:
If you feel better by purging the headspace air with N2 or Ar to rid it of O2, ok. However, I think it is a negligible effect. 3 mL of headspace air at 25% O2 will give enough O2 to at most react with about 5 mg of nicotine. And that is only if it all reacts.
...... In a liter of 100.00 mg/mL nic, 8 mg loss will make it 99.99 mg/mL. Within even pretty tight experimental error, that is essentially zero.
As for the V3, I honestly have no clue. I certainly believe it works in preventing oxidation, as theoretically the ascorbic acid will scavenge the available O2 before the nic reacts with it. It works well in food packaging, for example it will keep cut apples from turning brown. What I have zero clue about is vaping the stuff.
Kurt's blurb on it:

Lately my vaping style has become different than what a traditional K-F usually offers. This new one is suppose to have way better Air flow ?
